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.
