When using Sildur's Enhanced Default shaders with this compat, everything that can move in create turns solid black when the player is stationary, and solid white when the player is moving.

On enabling the shader the log repeats:
[12:56:39] [Render thread/WARN] [ne.co.ir.pi.tr.tr.CompatibilityTransformer/]: The in declaration 'NdotLight' in the FRAGMENT shader that is never assigned to in the previous stage VERTEX has been compatibility-patched by adding an initialization for it. See debugging.md for more information.
