Multiple-Scattering Microfacet BSDFs with the Smith Model

Eric Heitz and his colleagues published one hell of a paper on rendering microfacet materials. It has lots of beautifully written mathematics, and is really well illustrated, evaluated, and the full source code is also published. Now it comes with a narrated supplementary video. The paper is available here (or click the image below), check it out!
