In the MDL SDK “v-cavities masking and and importance sampling utility” https://github.com/NVIDIA/MDL-SDK/blob/3e6182bc3141ea79c10ddf092a081232ced8e5f3/src/mdl/jit/libbsdf/libbsdf.cpp#L594 is implemented.
I saw “Microfacet-based Normal Mapping for Robust Monte Carlo Path Tracing” (also from Eric Heitz)
https://blogs.unity3d.com/2017/10/02/microfacet-based-normal-mapping-for-robust-monte-carlo-path-tracing/?_ga=2.229676249.491408733.1564437340-820844567.1564437340 including source code for mitsuba.
Is that already implemented in the MDL SDK ? If not, are there any plans to add it ?
It would be great!
Any answer/advice appreciated, how I could add it on my own (if its not present).
thank you very much!
