Capture its surroundings as a dual paraboloid image, and stores versions of it with increasing levels of blur to simulate different material roughnesses.

The [ReflectionProbe] is used to create high-quality reflections at a low performance cost (when [member update_mode] is [constant UPDATE_ONCE]). [ReflectionProbe]s can be blended together and with the rest of the scene smoothly. [ReflectionProbe]s can also be combined with [GIProbe] and screen-space reflections ([member Environment.ss_reflections_enabled]) to get more accurate reflections in specific areas. [ReflectionProbe]s render all objects within their [member cull_mask], so updating them can be quite expensive. It is best to update them once with the important static objects and then leave them as-is.
|
|
[b]Note:[/b] Unlike [GIProbe], [ReflectionProbe]s only source their environment from a [WorldEnvironment] node. If you specify an [Environment] resource within a [Camera] node, it will be ignored by the [ReflectionProbe]. This can lead to incorrect lighting within the [ReflectionProbe].
|
|
[b]Note:[/b] By default, Godot will only render 16 reflection probes. If you need more, increase the number of atlas subdivisions. This setting can be found in [member ProjectSettings.rendering/quality/reflections/atlas_subdiv].
|
|
[b]Note:[/b] The GLES2 backend will only display two reflection probes at the same time for a single mesh. If possible, split up large meshes that span over multiple reflection probes into smaller ones.

|
<member name="box_projection" type="bool" setter="set_enable_box_projection" getter="is_box_projection_enabled" default="false">
|
|
If [code]true[/code], enables box projection. This makes reflections look more correct in rectangle-shaped rooms by offsetting the reflection center depending on the camera's location.
|
|
[b]Note:[/b] To better fit rectangle-shaped rooms that are not aligned to the grid, you can rotate the [ReflectionProbe] node.
|
|
</member>
|
|
<member name="cull_mask" type="int" setter="set_cull_mask" getter="get_cull_mask" default="1048575">
|
|
Sets the cull mask which determines what objects are drawn by this probe. Every [VisualInstance] with a layer included in this cull mask will be rendered by the probe. To improve performance, it is best to only include large objects which are likely to take up a lot of space in the reflection.
|
|
</member>
|
|
<member name="enable_shadows" type="bool" setter="set_enable_shadows" getter="are_shadows_enabled" default="false">
|
|
If [code]true[/code], computes shadows in the reflection probe. This makes the reflection probe slower to render; you may want to disable this if using the [constant UPDATE_ALWAYS] [member update_mode].
|
|
</member>
|
|
<member name="extents" type="Vector3" setter="set_extents" getter="get_extents" default="Vector3( 1, 1, 1 )">
|
|
The size of the reflection probe. The larger the extents the more space covered by the probe which will lower the perceived resolution. It is best to keep the extents only as large as you need them.
|
|
[b]Note:[/b] To better fit areas that are not aligned to the grid, you can rotate the [ReflectionProbe] node.

</member>
|
|
<member name="intensity" type="float" setter="set_intensity" getter="get_intensity" default="1.0">
|
|
Defines the reflection intensity. Intensity modulates the strength of the reflection.
|
|
</member>
|
|
<member name="interior_ambient_color" type="Color" setter="set_interior_ambient" getter="get_interior_ambient" default="Color( 0, 0, 0, 1 )">
|
|
Sets the ambient light color to be used when this probe is set to [member interior_enable].
|
|
</member>
|
|
<member name="interior_ambient_contrib" type="float" setter="set_interior_ambient_probe_contribution" getter="get_interior_ambient_probe_contribution" default="0.0">
|
|
Sets the contribution value for how much the reflection affects the ambient light for this reflection probe when set to [member interior_enable]. Useful so that ambient light matches the color of the room.
|
|
</member>
|
|
<member name="interior_ambient_energy" type="float" setter="set_interior_ambient_energy" getter="get_interior_ambient_energy" default="1.0">
|
|
Sets the energy multiplier for this reflection probe's ambient light contribution when set to [member interior_enable].
|
|
</member>
|
|
<member name="interior_enable" type="bool" setter="set_as_interior" getter="is_set_as_interior" default="false">
|
|
If [code]true[/code], reflections will ignore sky contribution. Ambient lighting is then controlled by the [code]interior_ambient_*[/code] properties.
|
|
</member>
|
|
<member name="max_distance" type="float" setter="set_max_distance" getter="get_max_distance" default="0.0">
|
|
The maximum distance away from the [ReflectionProbe] an object can be before it is culled. Decrease this to improve performance, especially when using the [constant UPDATE_ALWAYS] [member update_mode].
|
|
</member>
|
|
<member name="origin_offset" type="Vector3" setter="set_origin_offset" getter="get_origin_offset" default="Vector3( 0, 0, 0 )">
|
|
Sets the origin offset to be used when this [ReflectionProbe] is in [member box_projection] mode. This can be set to a non-zero value to ensure a reflection fits a rectangle-shaped room, while reducing the amount of objects that "get in the way" of the reflection.
|
|
</member>
|
|
<member name="update_mode" type="int" setter="set_update_mode" getter="get_update_mode" enum="ReflectionProbe.UpdateMode" default="0">
|
|
Sets how frequently the [ReflectionProbe] is updated. Can be [constant UPDATE_ONCE] or [constant UPDATE_ALWAYS].
|
|
</member>
|
|
</members>
|
|
<constants>
|
|
<constant name="UPDATE_ONCE" value="0" enum="UpdateMode">
|
|
Update the probe once on the next frame (recommended for most objects). The corresponding radiance map will be generated over the following six frames. This takes more time to update than [constant UPDATE_ALWAYS], but it has a lower performance cost and can result in higher-quality reflections. The ReflectionProbe is updated when its transform changes, but not when nearby geometry changes. You can force a [ReflectionProbe] update by moving the [ReflectionProbe] slightly in any direction.
|
|
</constant>
|
|
<constant name="UPDATE_ALWAYS" value="1" enum="UpdateMode">
|
|
Update the probe every frame. This provides better results for fast-moving dynamic objects (such as cars). However, it has a significant performance cost. Due to the cost, it's recommended to only use one ReflectionProbe with [constant UPDATE_ALWAYS] at most per scene. For all other use cases, use [constant UPDATE_ONCE].
