Introduction: Godot uses a shading language similar to GLSL ES 3.0. Most datatypes and functions are supported, and the few remaining ones will likely be added over time. If you are already familia...

Note that the source_color hint doesn't work on global uniforms. The workaround is to do the color conversion using the formula shared by clayjohn on the Github issue:

ALBEDO = mix(pow((col.rgb + vec3(0.055)) * (1.0 / (1.0 + 0.055)), vec3(2.4)), col.rgb * (1.0 / 12.92), lessThan(col.rgb, vec3(0.04045)));

It says "Per instance Uniforms are only available in Spatial (3D) shaders". I think that's no longer true as of 4.4?

Albedo means color for anyone else wandering.

For anyone looking for references to the TIME variable, it is found in the list of shader specific built-ins. Despite being documented identically for each shader, this information is duplicated. Some sort of index cross-reference would be nice in these situations.
