Instead of updating all viewports, then blitting all viewports
to the backbuffer, then swapping all buffers, we run through
all viewports and render, blit, and swap backbuffer before
going to the next viewport.
Sibling SubViewports must be rendered in the same order as in the Scene Tree, from top to bottom. _sort_active_viewports() reversed their order.
Fixes#65545
Values lower than 1.0 can be used to make the fog rendering not fully
obstruct the sky. This can be desired when using fog as a purely
atmospheric effect, without intending to use fog for open world fog
fading.
When set to 0.0, fog rendering behavior will be similar to Godot 3.x
where sky rendering was never affected by fog.
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.
In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.
Per-light energy gives more control to the user on the final result of
volumetric fog. Specific lights can be fully excluded from volumetric fog
by setting their volumetric fog energy to 0, which improves performance
slightly. This can also be used to prevent short-lived dynamic effects
from poorly interacting with volumetric fog, as it's updated over several
frames by default unless temporal reprojection is disabled.
Volumetric fog shadows now obey Light3D's Shadow Opacity property as well.
The shadow fog fade property was removed as it had little visible impact
on the final scene's rendering.
This provides a benefit similar to FSR 1.0 (greater texture sharpness
at the cost of some graininess at sub-native resolution scales), but
without the added performance cost of FSR 1.0.
At this time, it works best in the Vulkan Renderers as they support using multiple samplers with the same texture.
In GLES3 this feature really only allows you to use the screen texture without mipmaps if you want to save the cost of generating them.
This can be used to make shadows translucent for a specific light.
The light distance fade system also uses this to smoothly fade the shadow
when the light fade transition distance is greater than 0.
Adds a FramebufferCache singletion that operates the same way as UniformSetCache.
Allows creating framebuffers on the fly (and keep them cached if re-requested) such as:
```C++
RID fb = FramebufferCache::get_singleton()->get_cache(texture1,texture2);
```
`shader_uniform` is now consistenly used across both per-shader
and per-instance shader uniform methods. This makes methods easier
to find in the class reference when looking for them.
This is consistent with the BaseMaterial3D filtering options.
It can be used for high-quality pixel art textures that remain sharp
when viewed at oblique angles, but prevents them from becoming grainy
thanks to mipmaps.
- Fade reflection towards inner margin and clip it at screen edges
instead of external margin.
- Round edges of the fade margin if both are being cut off to prevent
sharp corners.

Particles won't move or rotate anymore with the node (or its parents)
by default. This new default behavior is generally more suited
to most use cases. Local coordinates can still be enabled on a per-node basis.
This affects both 2D and 3D particles, and both CPU and GPU-based particles.
this commit implements just enough of dummy mesh_storage so collision shapes are still generated in the headless mode
implementation was inspired by rasterizer_dummy.h from Godot3
- Increase the default non-volumetric fog density to 0.01 to make
adjustments more visible.
- Use a less saturated non-volumetric fog color by default
(a mix of the sky and horizon colors of the new default
ProceduralSkyMaterial).
- Set Volumetric Fog Gi Inject to 1.0 by default. Injecting GI results
in more realistic appearance of volumetric fog, at a very low
performance cost.
Overall brightness is similar to the previous settings, but lighting
now fades off more naturally and reflections feature indirect lighting.
Performance is identical.
- Enable Use Two Bounces by default.
- Decrease Propagation to 0.5 to compensate for the second bounce.
This can be used to recolor special effects such as fake area fog
without having to create separate textures for each color.
- Improve the Decal class documentation.
Mipmap LOD bias can be useful to improve the appearance of distant
textures without increasing anisotropic filtering (or in situations
where anisotropic filtering is not effective).
`fsr_mipmap_bias` was renamed to `texture_mipmap_bias` accordingly.
The property hint now allows for greater precision as well.
- Validate format conservatively. (This is to have VRS images created regardless whether VRS attachments are supported, which avoids errors in places where the code assumes such images were created on low-spec GPUs.)
- Create a non-layered default VRS image, which is what Vulkan (and D3D12, by the way) expect.
The new default values are more usable in real world scenarios
when smooth fading of distant decals is desired for performance reasons.
The Decal distance fade property hints were adjusted based on the
GeometryInstance3D visibility range fade property hints. `or_greater`
was also added to allow specifying larger values if needed.
Example with TAA: by default it is `false` in project settings and in
the Viewport node. When the scene tree is created, Viewport.set_use_taa()
is called with the value from ProjectSettings. But because the default
values are already the same, RenderingServer isn't called.
The Viewport struct in the RenderingServer does not initialize this field,
so TAA gets randomly enabled when the game starts with default settings.
Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
* Moved preprocessor to Shader and ShaderInclude
* Clean up RenderingServer side
* Preprocessor is separate from parser now, but it emits tokens with include location hints.
* Improved ShaderEditor validation code
* Added include file code completion
* Added notification for all files affected by a broken include.
`rendering/quality/shadows` is now `rendering/quality/positional_shadow`
to explicitly denote that the settings only affect positional light shadows,
not directional light shadows.
Shadow atlas settings now contain the word "atlas" for easier searching.
Soft shadow quality settings were renamed to contain the word "filter".
This makes the settings appear when searching for "filter" in the
project settings dialog, like in Godot 3.x.
Spartan Engine has recently removed its own internal TAA in favor
of FSR 2.0. The link has been changed to point to a fixed commit,
so the link will keep working as long as the repository exists.
Antialiased lines with a width of 2 pixels or more now use a smaller
feather width of 1.25 instead of 2.0. This makes them look sharper
and better preserves their original shape while still having good
antialiasing quality.
This also improves the appearance of thin antialiased lines by
slightly increasing their feather size (from 1.0 to 1.25). It
makes them appear a tad thicker, but the antialiasing quality is
much improved by doing this.
* Allows running the game in "movie writer" mode.
* It ensures entirely stable framerate, so your run can be saved stable and with proper sound (which is impossible if your CPU/GPU can't sustain doing this in real-time).
* If disabling vsync, it can save movies faster than the game is run, but if you want to control the interaction it can get difficult.
* Implements a simple, default MJPEG writer.
This new features has two main use cases, which have high demand:
* Saving game videos in high quality and ensuring the frame rate is *completely* stable, always.
* Using Godot as a tool to make movies and animations (which is ideal if you want interaction, or creating them procedurally. No other software is as good for this).
**Note**: This feature **IS NOT** for capturing real-time footage. Use something like OBS, SimpleScreenRecorder or FRAPS to achieve that, as they do a much better job at intercepting the compositor than Godot can probably do using Vulkan or OpenGL natively. If your game runs near real-time when capturing, you can still use this feature but it will play no sound (sound will be saved directly).
Usage:
$ godot --write-movie movie.avi [scene_file.tscn]
Missing:
* Options for configuring video writing via GLOBAL_DEF
* UI Menu for launching with this mode from the editor.
* Add to list of command line options.
* Add a feature tag to override configurations when movie writing (fantastic for saving videos with highest quality settings).
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)
- Specular can now be set above 1.0.
- Blur can be set to 0 to disable shadow blurring entirely, which is useful
on lights that have a non-zero size.
- When shadow blurring is disabled, lights that have a non-zero size will
not use PCSS-like soft shadows, speeding up shadow rendering
considerably.
- Some property hints now allow more precise values.
This has several benefits:
- Transparency sorting issues inherent to alpha blending no longer occur.
- Alpha hash materials can now cast shadows (also works with
GeometryInstance3D Transparency's property for alpha hash materials).
- Higher performance.
Initial TAA support based on the implementation in Spartan Engine.
Motion vectors are correctly generated for camera and mesh movement, but there is no support for other things like particles or skeleton deformations.
* Replace case-by-case extraction with PNAME & GNAME
* Fix group handling when group hint begins with property name
* Exclude properties that are PROPERTY_USAGE_NO_EDITOR
* Extract missing ADD_ARRAY*, ADD_SUBGROUP* macros
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
