Modeling multiple scattering in microfacet theory is considered an important open problem because a non-negligible portion of the energy leaving rough surfaces is due to paths that bounce multiple times. Researchers from the Karlsruhe Institute of Technology have made available a paper with a method that pushes the Smith microsurface model forward and derives its missing multiple-scattering component.

Wow, that’s gonna speed things up 🙂
Just wondering who’s going to integrate it first now. Vray ? Arnold ?
Cool stuff I have Real – time PBR approximation for that effect.
