0e56b64fc4 Fix albedo value wraparound in Compatibility render mode 
Using the Compatibility renderer results in wrapped albedo values if a custom shader returns albedo values outside the expected range of [0,1].

This commit fixed this issue by clamping the albedo value to [0,1] right after the custom shader is executed.

Fixes #91919

e378083fa5 fix typo in e41064388e breaking gles3 2024-05-02 00:32:39 +02:00

e41064388e reverted naming to premul alpha (no T) 
Initially 3d had premulT alpha as a keyword.
Since Canvas item uses mixed premul and premult as keywords,
3D is changed as well to keep consistency with 2D.
Unfortunately this keeps inconsistency with the internal ENUM.

Style: Mark clang-format 16 as supported for pre-commit hook 
It only introduced a difference in a .glsl file, which I've worked
around by removing an empty line. This keeps formatting consistent
between clang-format 15 and 16.

Also added a change in the 3-to-4 project converter to fix bogus
formatting in clang-format < 17.

51ed3aef63 Vertex and attribute compression to reduce the size of the vertex format. 
This allows Godot to automatically compress meshes to save a lot of bandwidth.

In general, this requires no interaction from the user and should result in
no noticable quality loss.

This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.

Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.

7c812cd7e9 Fix use of discard in shaders 
discard was being included in all shaders set to depth pass opaque, which is the majority of shaders

Instead it should only be used with alpha prepass materials

intensity of specular contributed by this light source, but it was
previously only used by the default material light shader, and not
possible to use in a custom light() shader.
