WebThe Substance PBR shaders for metal/roughness and specular/ glossiness use GGX BRDF and do not use any value remapping for roughness/glossiness. However, if any … WebGGX A method that is faster than Multiple-scattering GGX but is less physically accurate. Selecting it enables the Transmission Roughness input. Multiple-scattering GGX Takes multiple bounce (scattering) events between microfacets into account. This gives a more energy conserving results, which would otherwise be visible as excessive darkening.
