EEVEE: Update LUT GGX generation shader This modifies the principled BSDF and the Glass BSDF which now have better fit to multiscatter GGX. Code to generate the LUT have been updated and can run at runtime. The refraction LUT has been changed to have the critical angle always centered around one pixel so that interpolation can be mitigated. Offline LUT data will be updated in another commit This simplify the BTDF retreival removing the manual clean cut at low roughness. This maximize the precision of the LUT by scalling the sides by the critical angle. I also touched the ior > 1.0 approximation to be smoother. Also incluse some cleanup of bsdf_sampling.glsl |
