Server for anything visible. The rendering server is the API backend for everything visible. The whole scene system mounts on it to display. The rendering server is completely opaque: the internals are entirely implementation-specific and cannot be accessed. The rendering server can be used to bypass the scene/[Node] system entirely. This can improve performance in cases where the scene system is the bottleneck, but won't improve performance otherwise (for instance, if the GPU is already fully utilized). Resources are created using the [code]*_create[/code] functions. These functions return [RID]s which are not references to the objects themselves, but opaque [i]pointers[/i] towards these objects. All objects are drawn to a viewport. You can use the [Viewport] attached to the [SceneTree] or you can create one yourself with [method viewport_create]. When using a custom scenario or canvas, the scenario or canvas needs to be attached to the viewport using [method viewport_set_scenario] or [method viewport_attach_canvas]. [b]Scenarios:[/b] In 3D, all visual objects must be associated with a scenario. The scenario is a visual representation of the world. If accessing the rendering server from a running game, the scenario can be accessed from the scene tree from any [Node3D] node with [method Node3D.get_world_3d]. Otherwise, a scenario can be created with [method scenario_create]. Similarly, in 2D, a canvas is needed to draw all canvas items. [b]3D:[/b] In 3D, all visible objects are comprised of a resource and an instance. A resource can be a mesh, a particle system, a light, or any other 3D object. In order to be visible resources must be attached to an instance using [method instance_set_base]. The instance must also be attached to the scenario using [method instance_set_scenario] in order to be visible. RenderingServer methods that don't have a prefix are usually 3D-specific (but not always). [b]2D:[/b] In 2D, all visible objects are some form of canvas item. In order to be visible, a canvas item needs to be the child of a canvas attached to a viewport, or it needs to be the child of another canvas item that is eventually attached to the canvas. 2D-specific RenderingServer methods generally start with [code]canvas_*[/code]. [b]Headless mode:[/b] Starting the engine with the [code]--headless[/code] [url=$DOCS_URL/tutorials/editor/command_line_tutorial.html]command line argument[/url] disables all rendering and window management functions. Most functions from [RenderingServer] will return dummy values in this case. $DOCS_URL/tutorials/performance/using_servers.html Bakes the material data of the Mesh passed in the [param base] parameter with optional [param material_overrides] to a set of [Image]s of size [param image_size]. Returns an array of [Image]s containing material properties as specified in [enum BakeChannels]. As the RenderingServer actual logic may run on an separate thread, accessing its internals from the main (or any other) thread will result in errors. To make it easier to run code that can safely access the rendering internals (such as [RenderingDevice] and similar RD classes), push a callable via this function so it will be executed on the render thread. Creates a camera attributes object and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]camera_attributes_[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [CameraAttributes]. Sets the parameters to use with the auto-exposure effect. These parameters take on the same meaning as their counterparts in [CameraAttributes] and [CameraAttributesPractical]. Sets the parameters to use with the DOF blur effect. These parameters take on the same meaning as their counterparts in [CameraAttributesPractical]. Sets the shape of the DOF bokeh pattern. Different shapes may be used to achieve artistic effect, or to meet performance targets. For more detail on available options see [enum DOFBokehShape]. Sets the quality level of the DOF blur effect to one of the options in [enum DOFBlurQuality]. [param use_jitter] can be used to jitter samples taken during the blur pass to hide artifacts at the cost of looking more fuzzy. Sets the exposure values that will be used by the renderers. The normalization amount is used to bake a given Exposure Value (EV) into rendering calculations to reduce the dynamic range of the scene. The normalization factor can be calculated from exposure value (EV100) as follows: [codeblock] func get_exposure_normalization(float ev100): return 1.0 / (pow(2.0, ev100) * 1.2) [/codeblock] The exposure value can be calculated from aperture (in f-stops), shutter speed (in seconds), and sensitivity (in ISO) as follows: [codeblock] func get_exposure(float aperture, float shutter_speed, float sensitivity): return log2((aperture * aperture) / shutterSpeed * (100.0 / sensitivity)) [/codeblock] Creates a 3D camera and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]camera_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [Camera3D]. Sets the camera_attributes created with [method camera_attributes_create] to the given camera. Sets the cull mask associated with this camera. The cull mask describes which 3D layers are rendered by this camera. Equivalent to [member Camera3D.cull_mask]. Sets the environment used by this camera. Equivalent to [member Camera3D.environment]. Sets camera to use frustum projection. This mode allows adjusting the [param offset] argument to create "tilted frustum" effects. Sets camera to use orthogonal projection, also known as orthographic projection. Objects remain the same size on the screen no matter how far away they are. Sets camera to use perspective projection. Objects on the screen becomes smaller when they are far away. Sets [Transform3D] of camera. If [code]true[/code], preserves the horizontal aspect ratio which is equivalent to [constant Camera3D.KEEP_WIDTH]. If [code]false[/code], preserves the vertical aspect ratio which is equivalent to [constant Camera3D.KEEP_HEIGHT]. Creates a canvas and returns the assigned [RID]. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. Canvas has no [Resource] or [Node] equivalent. Subsequent drawing commands will be ignored unless they fall within the specified animation slice. This is a faster way to implement animations that loop on background rather than redrawing constantly. Draws a circle on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_circle]. If [param ignore] is [code]true[/code], ignore clipping on items drawn with this canvas item until this is called again with [param ignore] set to false. See also [method CanvasItem.draw_lcd_texture_rect_region]. Draws a line on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_line]. Draws a mesh created with [method mesh_create] with given [param transform], [param modulate] color, and [param texture]. This is used internally by [MeshInstance2D]. See also [method CanvasItem.draw_msdf_texture_rect_region]. Draws a 2D multiline on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_multiline] and [method CanvasItem.draw_multiline_colors]. Draws a 2D [MultiMesh] on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_multimesh]. Draws a nine-patch rectangle on the [CanvasItem] pointed to by the [param item] [RID]. Draws particles on the [CanvasItem] pointed to by the [param item] [RID]. Draws a 2D polygon on the [CanvasItem] pointed to by the [param item] [RID]. If you need more flexibility (such as being able to use bones), use [method canvas_item_add_triangle_array] instead. See also [method CanvasItem.draw_polygon]. Draws a 2D polyline on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_polyline] and [method CanvasItem.draw_polyline_colors]. Draws a 2D primitive on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_primitive]. Draws a rectangle on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_rect]. Sets a [Transform2D] that will be used to transform subsequent canvas item commands. Draws a 2D textured rectangle on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_texture_rect] and [method Texture2D.draw_rect]. Draws the specified region of a 2D textured rectangle on the [CanvasItem] pointed to by the [param item] [RID]. See also [method CanvasItem.draw_texture_rect_region] and [method Texture2D.draw_rect_region]. Draws a triangle array on the [CanvasItem] pointed to by the [param item] [RID]. This is internally used by [Line2D] and [StyleBoxFlat] for rendering. [method canvas_item_add_triangle_array] is highly flexible, but more complex to use than [method canvas_item_add_polygon]. [b]Note:[/b] [param count] is unused and can be left unspecified. Clears the [CanvasItem] and removes all commands in it. Creates a new CanvasItem instance and returns its [RID]. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_item_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [CanvasItem]. Sets the canvas group mode used during 2D rendering for the canvas item specified by the [param item] RID. For faster but more limited clipping, use [method canvas_item_set_clip] instead. [b]Note:[/b] The equivalent node functionality is found in [CanvasGroup] and [member CanvasItem.clip_children]. If [param clip] is [code]true[/code], makes the canvas item specified by the [param item] RID not draw anything outside of its rect's coordinates. This clipping is fast, but works only with axis-aligned rectangles. This means that rotation is ignored by the clipping rectangle. For more advanced clipping shapes, use [method canvas_item_set_canvas_group_mode] instead. [b]Note:[/b] The equivalent node functionality is found in [member Label.clip_text], [RichTextLabel] (always enabled) and more. Sets the [CanvasItem] to copy a rect to the backbuffer. If [param use_custom_rect] is [code]true[/code], sets the custom visibility rectangle (used for culling) to [param rect] for the canvas item specified by [param item]. Setting a custom visibility rect can reduce CPU load when drawing lots of 2D instances. If [param use_custom_rect] is [code]false[/code], automatically computes a visibility rectangle based on the canvas item's draw commands. Sets the default texture filter mode for the canvas item specified by the [param item] RID. Equivalent to [member CanvasItem.texture_filter]. Sets the default texture repeat mode for the canvas item specified by the [param item] RID. Equivalent to [member CanvasItem.texture_repeat]. If [param enabled] is [code]true[/code], enables multichannel signed distance field rendering mode for the canvas item specified by the [param item] RID. This is meant to be used for font rendering, or with specially generated images using [url=https://github.com/Chlumsky/msdfgen]msdfgen[/url]. If [param enabled] is [code]true[/code], draws the canvas item specified by the [param item] RID behind its parent. Equivalent to [member CanvasItem.show_behind_parent]. Sets the index for the [CanvasItem]. Sets the light [param mask] for the canvas item specified by the [param item] RID. Equivalent to [member CanvasItem.light_mask]. Sets a new [param material] to the canvas item specified by the [param item] RID. Equivalent to [member CanvasItem.material]. Multiplies the color of the canvas item specified by the [param item] RID, while affecting its children. See also [method canvas_item_set_self_modulate]. Equivalent to [member CanvasItem.modulate]. Sets a parent [CanvasItem] to the [CanvasItem]. The item will inherit transform, modulation and visibility from its parent, like [CanvasItem] nodes in the scene tree. Multiplies the color of the canvas item specified by the [param item] RID, without affecting its children. See also [method canvas_item_set_modulate]. Equivalent to [member CanvasItem.self_modulate]. If [param enabled] is [code]true[/code], child nodes with the lowest Y position are drawn before those with a higher Y position. Y-sorting only affects children that inherit from the canvas item specified by the [param item] RID, not the canvas item itself. Equivalent to [member CanvasItem.y_sort_enabled]. Sets the [param transform] of the canvas item specified by the [param item] RID. This affects where and how the item will be drawn. Child canvas items' transforms are multiplied by their parent's transform. Equivalent to [member Node2D.transform]. Sets if the [CanvasItem] uses its parent's material. Sets the rendering visibility layer associated with this [CanvasItem]. Only [Viewport] nodes with a matching rendering mask will render this [CanvasItem]. Sets the given [CanvasItem] as visibility notifier. [param area] defines the area of detecting visibility. [param enter_callable] is called when the [CanvasItem] enters the screen, [param exit_callable] is called when the [CanvasItem] exits the screen. If [param enable] is [code]false[/code], the item will no longer function as notifier. This method can be used to manually mimic [VisibleOnScreenNotifier2D]. Sets the visibility of the [CanvasItem]. If this is enabled, the Z index of the parent will be added to the children's Z index. Sets the [CanvasItem]'s Z index, i.e. its draw order (lower indexes are drawn first). Attaches the canvas light to the canvas. Removes it from its previous canvas. Creates a canvas light and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_light_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [Light2D]. Attaches a light occluder to the canvas. Removes it from its previous canvas. Creates a light occluder and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_light_occluder_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [LightOccluder2D]. Enables or disables light occluder. The light mask. See [LightOccluder2D] for more information on light masks. Sets a light occluder's polygon. Sets a light occluder's [Transform2D].

Equivalent to [member PointLight2D.texture]. Sets the offset of a [PointLight2D]'s texture. Equivalent to [member PointLight2D.offset]. Sets the scale factor of a [PointLight2D]'s texture. Equivalent to [member PointLight2D.texture_scale]. Sets the canvas light's [Transform2D]. Sets the Z range of objects that will be affected by this light. Equivalent to [member Light2D.range_z_min] and [member Light2D.range_z_max]. Creates a new light occluder polygon and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_occluder_polygon_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [OccluderPolygon2D]. Sets an occluder polygons cull mode. See [enum CanvasOccluderPolygonCullMode] constants. Sets the shape of the occluder polygon. A copy of the canvas item will be drawn with a local offset of the mirroring [Vector2]. Modulates all colors in the given canvas. Sets the [member ProjectSettings.rendering/2d/shadow_atlas/size] to use for [Light2D] shadow rendering (in pixels). The value is rounded up to the nearest power of 2. Creates a canvas texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]canvas_texture_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. See also [method texture_2d_create]. [b]Note:[/b] The equivalent resource is [CanvasTexture] and is only meant to be used in 2D rendering, not 3D. Sets the [param channel]'s [param texture] for the canvas texture specified by the [param canvas_texture] RID. Equivalent to [member CanvasTexture.diffuse_texture], [member CanvasTexture.normal_texture] and [member CanvasTexture.specular_texture]. Sets the [param base_color] and [param shininess] to use for the canvas texture specified by the [param canvas_texture] RID. Equivalent to [member CanvasTexture.specular_color] and [member CanvasTexture.specular_shininess]. Sets the texture [param filter] mode to use for the canvas texture specified by the [param canvas_texture] RID. Sets the texture [param repeat] mode to use for the canvas texture specified by the [param canvas_texture] RID. Creates a RenderingDevice that can be used to do draw and compute operations on a separate thread. Cannot draw to the screen nor share data with the global RenderingDevice. [b]Note:[/b] When using the OpenGL backend or when running in headless mode, this function always returns [code]null[/code]. Creates a decal and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]decal_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. To place in a scene, attach this decal to an instance using [method instance_set_base] using the returned RID. [b]Note:[/b] The equivalent node is [Decal]. Sets the [param albedo_mix] in the decal specified by the [param decal] RID. Equivalent to [member Decal.albedo_mix]. Sets the cull [param mask] in the decal specified by the [param decal] RID.

Equivalent to [member Decal.distance_fade_enabled], [member Decal.distance_fade_begin] and [member Decal.distance_fade_length]. Sets the emission [param energy] in the decal specified by the [param decal] RID. Equivalent to [member Decal.emission_energy]. Sets the upper fade ([param above]) and lower fade ([param below]) in the decal specified by the [param decal] RID. Equivalent to [member Decal.upper_fade] and [member Decal.lower_fade]. Sets the color multiplier in the decal specified by the [param decal] RID to [param color]. Equivalent to [member Decal.modulate]. Sets the normal [param fade] in the decal specified by the [param decal] RID. Equivalent to [member Decal.normal_fade]. Sets the [param size] of the decal specified by the [param decal] RID. Equivalent to [member Decal.size]. Sets the [param texture] in the given texture [param type] slot for the specified decal. Equivalent to [method Decal.set_texture]. Sets the texture [param filter] mode to use when rendering decals. This parameter is global and cannot be set on a per-decal basis. Creates a directional light and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID can be used in most [code]light_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. To place in a scene, attach this directional light to an instance using [method instance_set_base] using the returned RID. [b]Note:[/b] The equivalent node is [DirectionalLight3D]. Sets the [param size] of the directional light shadows in 3D. See also [member ProjectSettings.rendering/lights_and_shadows/directional_shadow/size]. This parameter is global and cannot be set on a per-viewport basis. Sets the filter [param quality] for directional light shadows in 3D. See also [member ProjectSettings.rendering/lights_and_shadows/directional_shadow/soft_shadow_filter_quality]. This parameter is global and cannot be set on a per-viewport basis. Generates and returns an [Image] containing the radiance map for the specified [param environment] RID's sky. This supports built-in sky material and custom sky shaders. If [param bake_irradiance] is [code]true[/code], the irradiance map is saved instead of the radiance map. The radiance map is used to render reflected light, while the irradiance map is used to render ambient light. See also [method sky_bake_panorama]. [b]Note:[/b] The image is saved in linear color space without any tonemapping performed, which means it will look too dark if viewed directly in an image editor. [b]Note:[/b] [param size] should be a 2:1 aspect ratio for the generated panorama to have square pixels. For radiance maps, there is no point in using a height greater than [member Sky.radiance_size], as it won't increase detail. Irradiance maps only contain low-frequency data, so there is usually no point in going past a size of 128×64 pixels when saving an irradiance map. Creates an environment and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]environment_*[/code] RenderingServer functions.

Configures signed distance field global illumination for the specified environment RID. See [code]sdfgi_*[/code] properties in [Environment] for more information. Sets the number of frames to use for converging signed distance field global illumination. Equivalent to [member ProjectSettings.rendering/global_illumination/sdfgi/frames_to_converge].

Sets the variables to be used with the screen-space ambient occlusion (SSAO) post-process effect. See [Environment] for more details. Sets the quality level of the screen-space ambient occlusion (SSAO) post-process effect. See [Environment] for more details. Sets the quality level of the screen-space indirect lighting (SSIL) post-process effect. See [Environment] for more details.

See [Environment] for more details. Sets the variables to be used with the volumetric fog post-process effect. See [Environment] for more details. Enables filtering of the volumetric fog scattering buffer. This results in much smoother volumes with very few under-sampling artifacts. Sets the resolution of the volumetric fog's froxel buffer. [param size] is modified by the screen's aspect ratio and then used to set the width and height of the buffer. While [param depth] is directly used to set the depth of the buffer. Creates a new fog volume and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]fog_volume_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [FogVolume]. Sets the [Material] of the fog volume. Can be either a [FogMaterial] or a custom [ShaderMaterial]. Sets the shape of the fog volume to either [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER], [constant RenderingServer.FOG_VOLUME_SHAPE_BOX] or [constant RenderingServer.FOG_VOLUME_SHAPE_WORLD]. Sets the size of the fog volume when shape is [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER] or [constant RenderingServer.FOG_VOLUME_SHAPE_BOX]. Forces redrawing of all viewports at once. Forces a synchronization between the CPU and GPU, which may be required in certain cases. Only call this when needed, as CPU-GPU synchronization has a performance cost. Tries to free an object in the RenderingServer. To avoid memory leaks, this should be called after using an object as memory management does not occur automatically when using RenderingServer directly. Returns the default clear color which is used when a specific clear color has not been selected. See also [method set_default_clear_color]. Returns the time taken to setup rendering on the CPU in milliseconds. This value is shared across all viewports and does [i]not[/i] require [method viewport_set_measure_render_time] to be enabled on a viewport to be queried. See also [method viewport_get_measured_render_time_cpu]. Returns the global RenderingDevice. [b]Note:[/b] When using the OpenGL backend or when running in headless mode, this function always returns [code]null[/code]. Returns a statistic about the rendering engine which can be used for performance profiling. See [enum RenderingServer.RenderingInfo] for a list of values that can be queried. See also [method viewport_get_render_info], which returns information specific to a viewport. [b]Note:[/b] Only 3D rendering is currently taken into account by some of these values, such as the number of draw calls. [b]Note:[/b] Rendering information is not available until at least 2 frames have been rendered by the engine. If rendering information is not available, [method get_rendering_info] returns [code]0[/code]. To print rendering information in [code]_ready()[/code] successfully, use the following: [codeblock] func _ready(): for _i in 2: await get_tree().process_frame print(RenderingServer.get_rendering_info(RENDERING_INFO_TOTAL_DRAW_CALLS_IN_FRAME)) [/codeblock] Returns the parameters of a shader. Returns the RID of the test cube. This mesh will be created and returned on the first call to [method get_test_cube], then it will be cached for subsequent calls. See also [method make_sphere_mesh]. Returns the RID of a 256×256 texture with a testing pattern on it (in [constant Image.FORMAT_RGB8] format). This texture will be created and returned on the first call to [method get_test_texture], then it will be cached for subsequent calls. See also [method get_white_texture]. Example of getting the test texture and applying it to a [Sprite2D] node: [codeblock] var texture_rid = RenderingServer.get_test_texture() var texture = ImageTexture.create_from_image(RenderingServer.texture_2d_get(texture_rid)) $Sprite2D.texture = texture [/codeblock] Returns the version of the graphics video adapter [i]currently in use[/i] (e.g. "1.2.189" for Vulkan, "3.3.0 NVIDIA 510.60.02" for OpenGL). This version may be different from the actual latest version supported by the hardware, as Godot may not always request the latest version. See also [method OS.get_video_adapter_driver_info]. [b]Note:[/b] When running a headless or server binary, this function returns an empty string. Returns the name of the video adapter (e.g. "GeForce GTX 1080/PCIe/SSE2"). [b]Note:[/b] When running a headless or server binary, this function returns an empty string. [b]Note:[/b] On the web platform, some browsers such as Firefox may report a different, fixed GPU name such as "GeForce GTX 980" (regardless of the user's actual GPU model). This is done to make fingerprinting more difficult. Returns the type of the video adapter. Since dedicated graphics cards from a given generation will [i]usually[/i] be significantly faster than integrated graphics made in the same generation, the device type can be used as a basis for automatic graphics settings adjustment. However, this is not always true, so make sure to provide users with a way to manually override graphics settings. [b]Note:[/b] When using the OpenGL backend or when running in headless mode, this function always returns [constant RenderingDevice.DEVICE_TYPE_OTHER]. Returns the vendor of the video adapter (e.g. "NVIDIA Corporation"). [b]Note:[/b] When running a headless or server binary, this function returns an empty string. Returns the ID of a 4×4 white texture (in [constant Image.FORMAT_RGB8] format). This texture will be created and returned on the first call to [method get_white_texture], then it will be cached for subsequent calls. See also [method get_test_texture]. Example of getting the white texture and applying it to a [Sprite2D] node: [codeblock] var texture_rid = RenderingServer.get_white_texture() var texture = ImageTexture.create_from_image(RenderingServer.texture_2d_get(texture_rid)) $Sprite2D.texture = texture [/codeblock] If [param half_resolution] is [code]true[/code], renders [VoxelGI] and SDFGI ([member Environment.sdfgi_enabled]) buffers at halved resolution on each axis (e.g. 960×540 when the viewport size is 1920×1080). This improves performance significantly when VoxelGI or SDFGI is enabled, at the cost of artifacts that may be visible on polygon edges. The loss in quality becomes less noticeable as the viewport resolution increases. [LightmapGI] rendering is not affected by this setting.

Returns the value of the global shader uniform specified by [param name]. [b]Note:[/b] [method global_shader_parameter_get] has a large performance penalty as the rendering thread needs to synchronize with the calling thread, which is slow.

Removes the previous skeleton from the instance. Creates a visual instance and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]instance_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. An instance is a way of placing a 3D object in the scenario. Objects like particles, meshes, reflection probes and decals need to be associated with an instance to be visible in the scenario using [method instance_set_base]. [b]Note:[/b] The equivalent node is [VisualInstance3D]. Creates a visual instance, adds it to the RenderingServer, and sets both base and scenario. It can be accessed with the RID that is returned. This RID will be used in all [code]instance_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method.

Sets the transparency for the given geometry instance. Equivalent to [member GeometryInstance3D.transparency]. A transparency of [code]0.0[/code] is fully opaque, while [code]1.0[/code] is fully transparent. Values greater than [code]0.0[/code] (exclusive) will force the geometry's materials to go through the transparent pipeline, which is slower to render and can exhibit rendering issues due to incorrect transparency sorting. However, unlike using a transparent material, setting [param transparency] to a value greater than [code]0.0[/code] (exclusive) will [i]not[/i] disable shadow rendering. In spatial shaders, [code]1.0 - transparency[/code] is set as the default value of the [code]ALPHA[/code] built-in. [b]Note:[/b] [param transparency] is clamped between [code]0.0[/code] and [code]1.0[/code], so this property cannot be used to make transparent materials more opaque than they originally are.

Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. Returns the number of bones allocated for this skeleton. Generates and returns an [Image] containing the radiance map for the specified [param sky] RID. This supports built-in sky material and custom sky shaders. If [param bake_irradiance] is [code]true[/code], the irradiance map is saved instead of the radiance map. The radiance map is used to render reflected light, while the irradiance map is used to render ambient light. See also [method environment_bake_panorama]. [b]Note:[/b] The image is saved in linear color space without any tonemapping performed, which means it will look too dark if viewed directly in an image editor. [param energy] values above [code]1.0[/code] can be used to brighten the resulting image. [b]Note:[/b] [param size] should be a 2:1 aspect ratio for the generated panorama to have square pixels. For radiance maps, there is no point in using a height greater than [member Sky.radiance_size], as it won't increase detail. Irradiance maps only contain low-frequency data, so there is usually no point in going past a size of 128×64 pixels when saving an irradiance map. Creates an empty sky and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]sky_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. Sets the material that the sky uses to render the background, ambient and reflection maps. Sets the process [param mode] of the sky specified by the [param sky] RID. Equivalent to [member Sky.process_mode]. Sets the [param radiance_size] of the sky specified by the [param sky] RID (in pixels). Equivalent to [member Sky.radiance_size]. Creates a spot light and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID can be used in most [code]light_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. To place in a scene, attach this spot light to an instance using [method instance_set_base] using the returned RID. Sets [member ProjectSettings.rendering/environment/subsurface_scattering/subsurface_scattering_quality] to use when rendering materials that have subsurface scattering enabled. Sets the [member ProjectSettings.rendering/environment/subsurface_scattering/subsurface_scattering_scale] and [member ProjectSettings.rendering/environment/subsurface_scattering/subsurface_scattering_depth_scale] to use when rendering materials that have subsurface scattering enabled. Creates a 2-dimensional texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]texture_2d_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [Texture2D]. [b]Note:[/b] Not to be confused with [method RenderingDevice.texture_create], which creates the graphics API's own texture type as opposed to the Godot-specific [Texture2D] resource. Returns an [Image] instance from the given [param texture] [RID]. Example of getting the test texture from [method get_test_texture] and applying it to a [Sprite2D] node: [codeblock] var texture_rid = RenderingServer.get_test_texture() var texture = ImageTexture.create_from_image(RenderingServer.texture_2d_get(texture_rid)) $Sprite2D.texture = texture [/codeblock] Returns an [Image] instance from the given [param texture] [RID] and [param layer]. Creates a 2-dimensional layered texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]texture_2d_layered_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [TextureLayered]. Creates a placeholder for a 2-dimensional layered texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]texture_2d_layered_*[/code] RenderingServer functions, although it does nothing when used. See also [method texture_2d_placeholder_create]. [b]Note:[/b] The equivalent resource is [PlaceholderTextureLayered]. Creates a placeholder for a 2-dimensional layered texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]texture_2d_layered_*[/code] RenderingServer functions, although it does nothing when used. See also [method texture_2d_layered_placeholder_create] Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [PlaceholderTexture2D]. Updates the texture specified by the [param texture] [RID] with the data in [param image]. A [param layer] must also be specified, which should be [code]0[/code] when updating a single-layer texture ([Texture2D]). [b]Note:[/b] The [param image] must have the same width, height and format as the current [param texture] data. Otherwise, an error will be printed and the original texture won't be modified. If you need to use different width, height or format, use [method texture_replace] instead. [b]Note:[/b] The equivalent resource is [Texture3D]. Returns 3D texture data as an array of [Image]s for the specified texture [RID]. Creates a placeholder for a 3-dimensional texture and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]texture_3d_*[/code] RenderingServer functions, although it does nothing when used. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent resource is [PlaceholderTexture3D]. Updates the texture specified by the [param texture] [RID]'s data with the data in [param data]. All the texture's layers must be replaced at once. [b]Note:[/b] The [param texture] must have the same width, height, depth and format as the current texture data. Otherwise, an error will be printed and the original texture won't be modified. If you need to use different width, height, depth or format, use [method texture_replace] instead. Returns the [enum Image.Format] for the texture. Returns the internal graphics handle for this texture object. For use when communicating with third-party APIs mostly with GDExtension. [b]Note:[/b] This function returns a [code]uint64_t[/code] which internally maps to a [code]GLuint[/code] (OpenGL) or [code]VkImage[/code] (Vulkan). Returns a texture [RID] that can be used with [RenderingDevice]. [i]Deprecated.[/i] ProxyTexture was removed in Godot 4, so this method does nothing when called and always returns a null [RID]. [i]Deprecated.[/i] ProxyTexture was removed in Godot 4, so this method cannot be used anymore. Creates a new texture object based on a texture created directly on the [RenderingDevice]. If the texture contains layers, [param layer_type] is used to define the layer type. Replaces [param texture]'s texture data by the texture specified by the [param by_texture] RID, without changing [param texture]'s RID. Sets a viewport's camera. Sets a viewport's canvas. Copies the viewport to a region of the screen specified by [param rect]. If [method viewport_set_render_direct_to_screen] is [code]true[/code], then the viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to. For example, you can set the root viewport to not render at all with the following code: FIXME: The method seems to be non-existent. [codeblocks] [gdscript] func _ready(): get_viewport().set_attach_to_screen_rect(Rect2()) $Viewport.set_attach_to_screen_rect(Rect2(0, 0, 600, 600)) [/gdscript] [/codeblocks] Using this can result in significant optimization, especially on lower-end devices. However, it comes at the cost of having to manage your viewports manually. For further optimization, see [method viewport_set_render_direct_to_screen]. Creates an empty viewport and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]viewport_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [Viewport]. Returns the CPU time taken to render the last frame in milliseconds. This [i]only[/i] includes time spent in rendering-related operations; scripts' [code]_process[/code] functions and other engine subsystems are not included in this readout. To get a complete readout of CPU time spent to render the scene, sum the render times of all viewports that are drawn every frame plus [method get_frame_setup_time_cpu]. Unlike [method Engine.get_frames_per_second], this method will accurately reflect CPU utilization even if framerate is capped via V-Sync or [member Engine.max_fps]. See also [method viewport_get_measured_render_time_gpu]. [b]Note:[/b] Requires measurements to be enabled on the specified [param viewport] using [method viewport_set_measure_render_time]. Otherwise, this method returns [code]0.0[/code]. Returns the GPU time taken to render the last frame in milliseconds. To get a complete readout of GPU time spent to render the scene, sum the render times of all viewports that are drawn every frame. Unlike [method Engine.get_frames_per_second], this method accurately reflects GPU utilization even if framerate is capped via V-Sync or [member Engine.max_fps]. See also [method viewport_get_measured_render_time_gpu]. [b]Note:[/b] Requires measurements to be enabled on the specified [param viewport] using [method viewport_set_measure_render_time]. Otherwise, this method returns [code]0.0[/code]. [b]Note:[/b] When GPU utilization is low enough during a certain period of time, GPUs will decrease their power state (which in turn decreases core and memory clock speeds). This can cause the reported GPU time to increase if GPU utilization is kept low enough by a framerate cap (compared to what it would be at the GPU's highest power state). Keep this in mind when benchmarking using [method viewport_get_measured_render_time_gpu]. This behavior can be overridden in the graphics driver settings at the cost of higher power usage. Returns a statistic about the rendering engine which can be used for performance profiling. This is separated into render pass [param type]s, each of them having the same [param info]s you can query (different passes will return different values). See [enum RenderingServer.ViewportRenderInfoType] for a list of render pass types and [enum RenderingServer.ViewportRenderInfo] for a list of information that can be queried. See also [method get_rendering_info], which returns global information across all viewports. [b]Note:[/b] Viewport rendering information is not available until at least 2 frames have been rendered by the engine. If rendering information is not available, [method viewport_get_render_info] returns [code]0[/code]. To print rendering information in [code]_ready()[/code] successfully, use the following: [codeblock] func _ready(): for _i in 2: await get_tree().process_frame print( RenderingServer.viewport_get_render_info(get_viewport().get_viewport_rid(), RenderingServer.VIEWPORT_RENDER_INFO_TYPE_VISIBLE, RenderingServer.VIEWPORT_RENDER_INFO_DRAW_CALLS_IN_FRAME) ) [/codeblock] Returns the render target for the viewport. Returns the viewport's last rendered frame. Detaches a viewport from a canvas and vice versa. If [code]true[/code], sets the viewport active, else sets it inactive. Sets the rendering mask associated with this [Viewport]. Only [CanvasItem] nodes with a matching rendering visibility layer will be rendered by this [Viewport]. Sets the stacking order for a viewport's canvas. [param layer] is the actual canvas layer, while [param sublayer] specifies the stacking order of the canvas among those in the same layer. Sets the transformation of a viewport's canvas. Sets the clear mode of a viewport. See [enum ViewportClearMode] for options. Sets the debug draw mode of a viewport. See [enum ViewportDebugDraw] for options. Sets the default texture filtering mode for the specified [param viewport] RID. See [enum CanvasItemTextureFilter] for options. Sets the default texture repeat mode for the specified [param viewport] RID. See [enum CanvasItemTextureRepeat] for options. If [code]true[/code], the viewport's canvas (i.e. 2D and GUI elements) is not rendered. If [code]true[/code], the viewport's 3D elements are not rendered. Sets the viewport's environment mode which allows enabling or disabling rendering of 3D environment over 2D canvas. When disabled, 2D will not be affected by the environment. When enabled, 2D will be affected by the environment if the environment background mode is [constant ENV_BG_CANVAS]. The default behavior is to inherit the setting from the viewport's parent. If the topmost parent is also set to [constant VIEWPORT_ENVIRONMENT_INHERIT], then the behavior will be the same as if it was set to [constant VIEWPORT_ENVIRONMENT_ENABLED]. Determines how sharp the upscaled image will be when using the FSR upscaling mode. Sharpness halves with every whole number. Values go from 0.0 (sharpest) to 2.0. Values above 2.0 won't make a visible difference. Sets the viewport's global transformation matrix. Sets the measurement for the given [param viewport] RID (obtained using [method Viewport.get_viewport_rid]). Once enabled, [method viewport_get_measured_render_time_cpu] and [method viewport_get_measured_render_time_gpu] will return values greater than [code]0.0[/code] when queried with the given [param viewport]. Sets the multisample anti-aliasing mode for 2D/Canvas on the specified [param viewport] RID. See [enum ViewportMSAA] for options. Sets the multisample anti-aliasing mode for 3D on the specified [param viewport] RID. See [enum ViewportMSAA] for options. Sets the [member ProjectSettings.rendering/occlusion_culling/bvh_build_quality] to use for occlusion culling. This parameter is global and cannot be set on a per-viewport basis. Sets the [member ProjectSettings.rendering/occlusion_culling/occlusion_rays_per_thread] to use for occlusion culling. This parameter is global and cannot be set on a per-viewport basis. Sets the viewport's parent to the viewport specified by the [param parent_viewport] RID. Sets the number of subdivisions to use in the specified shadow atlas [param quadrant] for omni and spot shadows. See also [method Viewport.set_positional_shadow_atlas_quadrant_subdiv]. Sets the [param size] of the shadow atlas's images (used for omni and spot lights) on the viewport specified by the [param viewport] RID. The value is rounded up to the nearest power of 2. If [param use_16_bits] is [code]true[/code], use 16 bits for the omni/spot shadow depth map. Enabling this results in shadows having less precision and may result in shadow acne, but can lead to performance improvements on some devices. [b]Note:[/b] If this is set to [code]0[/code], no positional shadows will be visible at all. This can improve performance significantly on low-end systems by reducing both the CPU and GPU load (as fewer draw calls are needed to draw the scene without shadows). If [code]true[/code], render the contents of the viewport directly to screen. This allows a low-level optimization where you can skip drawing a viewport to the root viewport. While this optimization can result in a significant increase in speed (especially on older devices), it comes at a cost of usability. When this is enabled, you cannot read from the viewport or from the screen_texture. You also lose the benefit of certain window settings, such as the various stretch modes. Another consequence to be aware of is that in 2D the rendering happens in window coordinates, so if you have a viewport that is double the size of the window, and you set this, then only the portion that fits within the window will be drawn, no automatic scaling is possible, even if your game scene is significantly larger than the window size. Sets the 3D resolution scaling mode. Bilinear scaling renders at different resolution to either undersample or supersample the viewport. FidelityFX Super Resolution 1.0, abbreviated to FSR, is an upscaling technology that produces high quality images at fast framerates by using a spatially aware upscaling algorithm. FSR is slightly more expensive than bilinear, but it produces significantly higher image quality. FSR should be used where possible. Scales the 3D render buffer based on the viewport size uses an image filter specified in [enum ViewportScaling3DMode] to scale the output image to the full viewport size. Values lower than [code]1.0[/code] can be used to speed up 3D rendering at the cost of quality (undersampling). Values greater than [code]1.0[/code] are only valid for bilinear mode and can be used to improve 3D rendering quality at a high performance cost (supersampling). See also [enum ViewportMSAA] for multi-sample antialiasing, which is significantly cheaper but only smoothens the edges of polygons. When using FSR upscaling, AMD recommends exposing the following values as preset options to users "Ultra Quality: 0.77", "Quality: 0.67", "Balanced: 0.59", "Performance: 0.5" instead of exposing the entire scale. Sets a viewport's scenario. The scenario contains information about environment information, reflection atlas, etc. Sets the viewport's screen-space antialiasing mode. Sets the viewport's 2D signed distance field [member ProjectSettings.rendering/2d/sdf/oversize] and [member ProjectSettings.rendering/2d/sdf/scale]. This is used when sampling the signed distance field in [CanvasItem] shaders as well as [GPUParticles2D] collision. This is [i]not[/i] used by SDFGI in 3D rendering. Sets the viewport's width and height in pixels. If [code]true[/code], canvas item transforms (i.e. origin position) are snapped to the nearest pixel when rendering. This can lead to a crisper appearance at the cost of less smooth movement, especially when [Camera2D] smoothing is enabled. Equivalent to [member ProjectSettings.rendering/2d/snap/snap_2d_transforms_to_pixel]. If [code]true[/code], canvas item vertices (i.e. polygon points) are snapped to the nearest pixel when rendering. This can lead to a crisper appearance at the cost of less smooth movement, especially when [Camera2D] smoothing is enabled. Equivalent to [member ProjectSettings.rendering/2d/snap/snap_2d_vertices_to_pixel]. Affects the final texture sharpness by reading from a lower or higher mipmap (also called "texture LOD bias"). Negative values make mipmapped textures sharper but grainier when viewed at a distance, while positive values make mipmapped textures blurrier (even when up close). To get sharper textures at a distance without introducing too much graininess, set this between [code]-0.75[/code] and [code]0.0[/code]. Enabling temporal antialiasing ([member ProjectSettings.rendering/anti_aliasing/quality/use_taa]) can help reduce the graininess visible when using negative mipmap bias. [b]Note:[/b] When the 3D scaling mode is set to FSR 1.0, this value is used to adjust the automatic mipmap bias which is calculated internally based on the scale factor. The formula for this is [code]-log2(1.0 / scale) + mipmap_bias[/code]. If [code]true[/code], the viewport renders its background as transparent. Sets when the viewport should be updated. See [enum ViewportUpdateMode] constants for options. If [code]true[/code], enables debanding on the specified viewport. Equivalent to [member ProjectSettings.rendering/anti_aliasing/quality/use_debanding]. If [code]true[/code], 2D rendering will use a high dynamic range (HDR) format framebuffer matching the bit depth of the 3D framebuffer. When using the Forward+ renderer this will be a [code]RGBA16[/code] framebuffer, while when using the Mobile renderer it will be a [code]RGB10_A2[/code] framebuffer. Additionally, 2D rendering will take place in linear color space and will be converted to sRGB space immediately before blitting to the screen (if the Viewport is attached to the screen). Practically speaking, this means that the end result of the Viewport will not be clamped into the [code]0-1[/code] range and can be used in 3D rendering without color space adjustments. This allows 2D rendering to take advantage of effects requiring high dynamic range (e.g. 2D glow) as well as substantially improves the appearance of effects requiring highly detailed gradients. This setting has the same effect as [member Viewport.use_hdr_2d]. [b]Note:[/b] This setting will have no effect when using the GL Compatibility renderer as the GL Compatibility renderer always renders in low dynamic range for performance reasons. If [code]true[/code], enables occlusion culling on the specified viewport. Equivalent to [member ProjectSettings.rendering/occlusion_culling/use_occlusion_culling]. If [code]true[/code], use Temporal Anti-Aliasing. Equivalent to [member ProjectSettings.rendering/anti_aliasing/quality/use_taa]. If [code]true[/code], the viewport uses augmented or virtual reality technologies. See [XRInterface]. Sets the Variable Rate Shading (VRS) mode for the viewport. If the GPU does not support VRS, this property is ignored. Equivalent to [member ProjectSettings.rendering/vrs/mode]. The texture to use when the VRS mode is set to [constant RenderingServer.VIEWPORT_VRS_TEXTURE]. Equivalent to [member ProjectSettings.rendering/vrs/texture]. Creates a new 3D visibility notifier object and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]visibility_notifier_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. To place in a scene, attach this mesh to an instance using [method instance_set_base] using the returned RID. [b]Note:[/b] The equivalent node is [VisibleOnScreenNotifier3D]. Creates a new voxel-based global illumination object and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]voxel_gi_*[/code] RenderingServer functions. Once finished with your RID, you will want to free the RID using the RenderingServer's [method free_rid] method. [b]Note:[/b] The equivalent node is [VoxelGI]. Used to inform the renderer what exposure normalization value was used while baking the voxel gi. This value will be used and modulated at run time to ensure that the voxel gi maintains a consistent level of exposure even if the scene-wide exposure normalization is changed at run time. For more information see [method camera_attributes_set_exposure]. Sets the [member VoxelGIData.bias] value to use on the specified [param voxel_gi]'s [RID].

Sets the [member VoxelGIData.use_two_bounces] value to use on the specified [param voxel_gi]'s [RID]. If [code]false[/code], disables rendering completely, but the engine logic is still being processed. You can call [method force_draw] to draw a frame even with rendering disabled. Emitted at the end of the frame, after the RenderingServer has finished updating all the Viewports. Emitted at the beginning of the frame, before the RenderingServer updates all the Viewports.

Flag used to mark that the array uses 8 bone weights instead of 4. Flag used to mark that the mesh does not have a vertex array and instead will infer vertex positions in the shader using indices and other information. Flag used to mark that a mesh is using compressed attributes (vertices, normals, tangents, UVs). When this form of compression is enabled, vertex positions will be packed into an RGBA16UNORM attribute and scaled in the vertex shader. The normal and tangent will be packed into an RG16UNORM representing an axis, and a 16-bit float stored in the A-channel of the vertex. UVs will use 16-bit normalized floats instead of full 32-bit signed floats. When using this compression mode you must use either vertices, normals, and tangents or only vertices. You cannot use normals without tangents. Importers will automatically enable this compression if they can. Flag used to mark the start of the bits used to store the mesh version.

The light's range. The size of the light when using spot light or omni light. The angular size of the light when using directional light. The light's attenuation. The spotlight's angle. The spotlight's attenuation. The maximum distance for shadow splits. Increasing this value will make directional shadows visible from further away, at the cost of lower overall shadow detail and performance (since more objects need to be included in the directional shadow rendering). Proportion of shadow atlas occupied by the first split. Proportion of shadow atlas occupied by the second split. Proportion of shadow atlas occupied by the third split. The fourth split occupies the rest. Proportion of shadow max distance where the shadow will start to fade out. Normal bias used to offset shadow lookup by object normal. Can be used to fix self-shadowing artifacts. Bias the shadow lookup to fix self-shadowing artifacts. Sets the size of the directional shadow pancake. The pancake offsets the start of the shadow's camera frustum to provide a higher effective depth resolution for the shadow. However, a high pancake size can cause artifacts in the shadows of large objects that are close to the edge of the frustum. Reducing the pancake size can help. Setting the size to [code]0[/code] turns off the pancaking effect. The light's shadow opacity. Values lower than [code]1.0[/code] make the light appear through shadows. This can be used to fake global illumination at a low performance cost. Blurs the edges of the shadow. Can be used to hide pixel artifacts in low resolution shadow maps. A high value can make shadows appear grainy and can cause other unwanted artifacts. Try to keep as near default as possible.

Only used when [member ProjectSettings.rendering/lights_and_shadows/use_physical_light_units] is [code]true[/code]. Represents the size of the [enum LightParam] enum. Light is ignored when baking. This is the fastest mode, but the light will be taken into account when baking global illumination. This mode should generally be used for dynamic lights that change quickly, as the effect of global illumination is less noticeable on those lights. Light is taken into account in static baking ([VoxelGI], [LightmapGI], SDFGI ([member Environment.sdfgi_enabled])). The light can be moved around or modified, but its global illumination will not update in real-time. This is suitable for subtle changes (such as flickering torches), but generally not large changes such as toggling a light on and off. Light is taken into account in dynamic baking ([VoxelGI] and SDFGI ([member Environment.sdfgi_enabled]) only). The light can be moved around or modified with global illumination updating in real-time. The light's global illumination appearance will be slightly different compared to [constant LIGHT_BAKE_STATIC]. This has a greater performance cost compared to [constant LIGHT_BAKE_STATIC]. When using SDFGI, the update speed of dynamic lights is affected by [member ProjectSettings.rendering/global_illumination/sdfgi/frames_to_update_lights]. Use a dual paraboloid shadow map for omni lights. Use a cubemap shadow map for omni lights. Slower but better quality than dual paraboloid. Use orthogonal shadow projection for directional light. Use 2 splits for shadow projection when using directional light. Use 4 splits for shadow projection when using directional light. Use DirectionalLight3D in both sky rendering and scene lighting. Only use DirectionalLight3D in scene lighting. Only use DirectionalLight3D in sky rendering. Lowest shadow filtering quality (fastest). Soft shadows are not available with this quality setting, which means the [member Light3D.shadow_blur] property is ignored if [member Light3D.light_size] and [member Light3D.light_angular_distance] is [code]0.0[/code]. [b]Note:[/b] The variable shadow blur performed by [member Light3D.light_size] and [member Light3D.light_angular_distance] is still effective when using hard shadow filtering. In this case, [member Light3D.shadow_blur] [i]is[/i] taken into account. However, the results will not be blurred, instead the blur amount is treated as a maximum radius for the penumbra. Very low shadow filtering quality (faster). When using this quality setting, [member Light3D.shadow_blur] is automatically multiplied by 0.75× to avoid introducing too much noise. This division only applies to lights whose [member Light3D.light_size] or [member Light3D.light_angular_distance] is [code]0.0[/code]). Low shadow filtering quality (fast). Medium low shadow filtering quality (average). High low shadow filtering quality (slow). When using this quality setting, [member Light3D.shadow_blur] is automatically multiplied by 1.5× to better make use of the high sample count.

Represents the size of the [enum DecalTexture] enum. Nearest-neighbor filter for decals (use for pixel art decals). No mipmaps are used for rendering, which means decals at a distance will look sharp but grainy. This has roughly the same performance cost as using mipmaps. Linear filter for decals (use for non-pixel art decals). No mipmaps are used for rendering, which means decals at a distance will look smooth but blurry. This has roughly the same performance cost as using mipmaps. Nearest-neighbor filter for decals (use for pixel art decals).

The amount of scaling can be set using [member Viewport.scaling_3d_scale]. Values less than [code]1.0[/code] will result in undersampling while values greater than [code]1.0[/code] will result in supersampling. A value of [code]1.0[/code] disables scaling. Use AMD FidelityFX Super Resolution 1.0 upscaling for the viewport's 3D buffer. The amount of scaling can be set using [member Viewport.scaling_3d_scale]. Values less than [code]1.0[/code] will be result in the viewport being upscaled using FSR. Values greater than [code]1.0[/code] are not supported and bilinear downsampling will be used instead.

Represents the size of the [enum ViewportScaling3DMode] enum. Do not update the viewport's render target. Update the viewport's render target once, then switch to [constant VIEWPORT_UPDATE_DISABLED]. Update the viewport's render target only when it is visible. This is the default value. Update the viewport's render target only when its parent is visible. Always update the viewport's render target. Always clear the viewport's render target before drawing. Never clear the viewport's render target.

Enable rendering of 3D environment over 2D canvas. Inherit enable/disable value from parent. If the topmost parent is also set to [constant VIEWPORT_ENVIRONMENT_INHERIT], then this has the same behavior as [constant VIEWPORT_ENVIRONMENT_ENABLED]. Represents the size of the [enum ViewportEnvironmentMode] enum. Do not oversize the 2D signed distance field. Occluders may disappear when touching the viewport's edges, and [GPUParticles3D] collision may stop working earlier than intended.

This has the lowest GPU requirements. Represents the size of the [enum ViewportSDFScale] enum. Multisample antialiasing for 3D is disabled. This is the default value, and also the fastest setting. Multisample antialiasing uses 2 samples per pixel for 3D. This has a moderate impact on performance. Multisample antialiasing uses 4 samples per pixel for 3D. This has a high impact on performance. Multisample antialiasing uses 8 samples per pixel for 3D. This has a very high impact on performance. Likely unsupported on low-end and older hardware. Represents the size of the [enum ViewportMSAA] enum. Do not perform any antialiasing in the full screen post-process. Use fast approximate antialiasing. FXAA is a popular screen-space antialiasing method, which is fast but will make the image look blurry, especially at lower resolutions.

Represents the size of the [enum ViewportRenderInfoType] enum. Debug draw is disabled. Default setting. Objects are displayed without light information. Objects are displayed with only light information. Objects are displayed semi-transparent with additive blending so you can see where they are drawing over top of one another. A higher overdraw (represented by brighter colors) means you are wasting performance on drawing pixels that are being hidden behind others. [b]Note:[/b] When using this debug draw mode, custom shaders will be ignored. This means vertex displacement won't be visible anymore. Debug draw draws objects in wireframe. Normal buffer is drawn instead of regular scene so you can see the per-pixel normals that will be used by post-processing effects. Objects are displayed with only the albedo value from [VoxelGI]s. Objects are displayed with only the lighting value from [VoxelGI]s. Objects are displayed with only the emission color from [VoxelGI]s.

In order for this display mode to work, you must have [member Environment.ssao_enabled] set in your [WorldEnvironment]. Draws the screen space indirect lighting texture instead of the scene so that you can clearly see how it is affecting objects. In order for this display mode to work, you must have [member Environment.ssil_enabled] set in your [WorldEnvironment].

Clustering determines where lights are positioned in screen-space, which allows the engine to only process these portions of the screen for lighting. Draws the [Decal] cluster. Clustering determines where decals are positioned in screen-space, which allows the engine to only process these portions of the screen for decals. Draws the [ReflectionProbe] cluster. Clustering determines where reflection probes are positioned in screen-space, which allows the engine to only process these portions of the screen for reflection probes. Draws the occlusion culling buffer. This low-resolution occlusion culling buffer is rasterized on the CPU and is used to check whether instances are occluded by other objects. Draws the motion vectors buffer. This is used by temporal antialiasing to correct for motion that occurs during gameplay. Internal buffer is drawn instead of regular scene so you can see the per-pixel output that will be used by post-processing effects. Variable rate shading is disabled. Variable rate shading uses a texture. Note, for stereoscopic use a texture atlas with a texture for each view. Variable rate shading texture is supplied by the primary [XRInterface]. Represents the size of the [enum ViewportVRSMode] enum. Automatically selects the appropriate process mode based on your sky shader. If your shader uses [code]TIME[/code] or [code]POSITION[/code], this will use [constant SKY_MODE_REALTIME]. If your shader uses any of the [code]LIGHT_*[/code] variables or any custom uniforms, this uses [constant SKY_MODE_INCREMENTAL]. Otherwise, this defaults to [constant SKY_MODE_QUALITY]. Uses high quality importance sampling to process the radiance map. In general, this results in much higher quality than [constant SKY_MODE_REALTIME] but takes much longer to generate. This should not be used if you plan on changing the sky at runtime. If you are finding that the reflection is not blurry enough and is showing sparkles or fireflies, try increasing [member ProjectSettings.rendering/reflections/sky_reflections/ggx_samples]. Uses the same high quality importance sampling to process the radiance map as [constant SKY_MODE_QUALITY], but updates over several frames. The number of frames is determined by [member ProjectSettings.rendering/reflections/sky_reflections/roughness_layers]. Use this when you need highest quality radiance maps, but have a sky that updates slowly. Uses the fast filtering algorithm to process the radiance map. In general this results in lower quality, but substantially faster run times. If you need better quality, but still need to update the sky every frame, consider turning on [member ProjectSettings.rendering/reflections/sky_reflections/fast_filter_high_quality]. [b]Note:[/b] The fast filtering algorithm is limited to 256×256 cubemaps, so [method sky_set_radiance_size] must be set to [code]256[/code]. Otherwise, a warning is printed and the overridden radiance size is ignored. Use the clear color as background. Use a specified color as the background. Use a sky resource for the background. Use a specified canvas layer as the background. This can be useful for instantiating a 2D scene in a 3D world. Do not clear the background, use whatever was rendered last frame as the background.

Specify a specific [Color] for ambient light. Gather ambient light from the [Sky] regardless of what the background is. Use the background for reflections. Disable reflections. Use the [Sky] for reflections regardless of what the background is. Additive glow blending mode. Mostly used for particles, glows (bloom), lens flare, bright sources. Screen glow blending mode. Increases brightness, used frequently with bloom. Soft light glow blending mode. Modifies contrast, exposes shadows and highlights (vivid bloom). Replace glow blending mode. Replaces all pixels' color by the glow value. This can be used to simulate a full-screen blur effect by tweaking the glow parameters to match the original image's brightness. Mixes the glow with the underlying color to avoid increasing brightness as much while still maintaining a glow effect. Output color as they came in. This can cause bright lighting to look blown out, with noticeable clipping in the output colors. Use the Reinhard tonemapper. Performs a variation on rendered pixels' colors by this formula: [code]color = color / (1 + color)[/code]. This avoids clipping bright highlights, but the resulting image can look a bit dull. Use the filmic tonemapper. This avoids clipping bright highlights, with a resulting image that usually looks more vivid than [constant ENV_TONE_MAPPER_REINHARD]. Use the Academy Color Encoding System tonemapper. ACES is slightly more expensive than other options, but it handles bright lighting in a more realistic fashion by desaturating it as it becomes brighter. ACES typically has a more contrasted output compared to [constant ENV_TONE_MAPPER_REINHARD] and [constant ENV_TONE_MAPPER_FILMIC]. [b]Note:[/b] This tonemapping operator is called "ACES Fitted" in Godot 3.x. Lowest quality of roughness filter for screen-space reflections.

Highest quality screen-space indirect lighting. Uses the adaptive target setting which can be dynamically adjusted to smoothly balance performance and visual quality. Use 50% scale for SDFGI on the Y (vertical) axis. SDFGI cells will be twice as short as they are wide. This allows providing increased GI detail and reduced light leaking with thin floors and ceilings. This is usually the best choice for scenes that don't feature much verticality. Use 75% scale for SDFGI on the Y (vertical) axis. This is a balance between the 50% and 100% SDFGI Y scales. Use 100% scale for SDFGI on the Y (vertical) axis. SDFGI cells will be as tall as they are wide. This is usually the best choice for highly vertical scenes. The downside is that light leaking may become more noticeable with thin floors and ceilings. Throw 4 rays per frame when converging SDFGI. This has the lowest GPU requirements, but creates the most noisy result. Throw 8 rays per frame when converging SDFGI. Throw 16 rays per frame when converging SDFGI. Throw 32 rays per frame when converging SDFGI. Throw 64 rays per frame when converging SDFGI. Throw 96 rays per frame when converging SDFGI.

Disables subsurface scattering entirely, even on materials that have [member BaseMaterial3D.subsurf_scatter_enabled] set to [code]true[/code]. This has the lowest GPU requirements. Low subsurface scattering quality. Medium subsurface scattering quality. High subsurface scattering quality. This has the highest GPU requirements. Calculate the DOF blur using a box filter. The fastest option, but results in obvious lines in blur pattern. Calculates DOF blur using a hexagon shaped filter. Calculates DOF blur using a circle shaped filter. Best quality and most realistic, but slowest. Use only for areas where a lot of performance can be dedicated to post-processing (e.g. cutscenes). Lowest quality DOF blur. This is the fastest setting, but you may be able to see filtering artifacts. Low quality DOF blur. Medium quality DOF blur. Highest quality DOF blur.

Does not affect view frustum culling. Represents the size of the [enum InstanceFlags] enum. Disable shadows from this instance. Cast shadows from this instance. Disable backface culling when rendering the shadow of the object. This is slightly slower but may result in more correct shadows. Only render the shadows from the object.

The simplest and fastest method of filtering, but the texture will look pixelized. The texture filter blends between the nearest 4 pixels. Use this when you want to avoid a pixelated style, but do not want mipmaps. The texture filter reads from the nearest pixel in the nearest mipmap. The fastest way to read from textures with mipmaps. The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps. The texture filter reads from the nearest pixel, but selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. The texture filter blends between the nearest 4 pixels and selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. This is the slowest of the filtering options, but results in the highest quality texturing. Max value for [enum CanvasItemTextureFilter] enum. Uses the default repeat mode for this [Viewport]. Disables textures repeating. Instead, when reading UVs outside the 0-1 range, the value will be clamped to the edge of the texture, resulting in a stretched out look at the borders of the texture. Enables the texture to repeat when UV coordinates are outside the 0-1 range. If using one of the linear filtering modes, this can result in artifacts at the edges of a texture when the sampler filters across the edges of the texture. Flip the texture when repeating so that the edge lines up instead of abruptly changing. Max value for [enum CanvasItemTextureRepeat] enum. Child draws over parent and is not clipped. Parent is used for the purposes of clipping only. Child is clipped to the parent's visible area, parent is not drawn.

Cubemap sampler global shader parameter ([code]global uniform samplerCube ...[/code]). Exposed as a [Cubemap] in the editor UI. Represents the size of the [enum GlobalShaderParameterType] enum. Number of objects rendered in the current 3D scene. This varies depending on camera position and rotation. Number of points, lines, or triangles rendered in the current 3D scene. This varies depending on camera position and rotation. Number of draw calls performed to render in the current 3D scene. This varies depending on camera position and rotation. Texture memory used (in bytes). Buffer memory used (in bytes). This includes vertex data, uniform buffers, and many miscellaneous buffer types used internally. Video memory used (in bytes). When using the Forward+ or mobile rendering backends, this is always greater than the sum of [constant RENDERING_INFO_TEXTURE_MEM_USED] and [constant RENDERING_INFO_BUFFER_MEM_USED], since there is miscellaneous data not accounted for by those two metrics. When using the GL Compatibility backend, this is equal to the sum of [constant RENDERING_INFO_TEXTURE_MEM_USED] and [constant RENDERING_INFO_BUFFER_MEM_USED]. Hardware supports shaders. This enum is currently unused in Godot 3.x. Hardware supports multithreading. This enum is currently unused in Godot 3.x.
