Merge pull request #96819 from clayjohn/GLES3-instance-uniforms 
Implement instance uniforms in Compatibility renderer
 2024-10-07 13:41:47 -06:00

Implement vertex shading 
This adds support in all backends, but the Compatibility renderer works the best.
Mobile and Forward+ can only support one directional light shader (the first in the tree)
While the Compatibility renderer supports any number of shadows.

Remove warning when project setting requests a larger global shader uniform buffer than the hardware supports. 
Instead provide a better error message when the limit is exceeded and avoid crash with a small limit.

Merge pull request #91399 from QbieShay/qbe/fix-pmul-name 
Revert premul alpha to spell without the T

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.

d1043a5f93 Enhance checks and user experience around tangents. 
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.

Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.

Warn users if they are trying to read from tangents without providing tangents.

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.

8452e6cdb3 Add SPECULAR_AMOUNT spatial light shader built-in 
Light3D has a light_specular property which is used to set the
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.
