[lightpreview] all geometry is pure white

[RandomErrorMessage]

When using lightpreview I get the following errors upon loading a BSP, and all geometry is pure white regardless of which mode I select. I tried building from 08ae1540de5e070debf8bf94cadfc4d573ab44d2 to see if this is a recent regression but nothing changed. My iGPU has OpenGL 3.30 Core, and up to 4.6 (compatibility profile).

[REPEATS UNTIL LOCATION 254 INCLUSIVE]

Suggests it might be the uniform float style_scalars[256]; causing this. Maybe too large of a uniform array?

What's the GPU, OS, GPU driver? I'm only testing on a 1070 Ti/Win11/NVIDIA 536.40 at the moment.

Yeah sounds like it didn't even load the other uniforms - it's calling glUniform1(value, 0) up until 254 since that's how many styles there are. We need error checking on load I think (we don't ever validate the uniform locations).

Oops. Nice catch.
