  • Add mx_microfacet_ggx_directional_albedo for computing a directional albedo for the GGX/Smith/Schlick BRDF.
  • Replace mirror Fresnel with directional albedo for BSDF layering.
  • Move Fresnel computation into the lighting integral for filtered importance sampling.
  • Add mx_average_roughness for converting from anisotropic to isotropic roughness.
