You never know when a link online is going to die, so it's better to just upload the file here.

Addressed by SPI also in RayTracing Gems III, A Microfacet Based Shadowing Function to Solve the Bump Terminator Problem, page 20.

Hi!
I am quite interested in this method as well.
I consider it is important for my research, therefore I have investigated the paper.
There is also source code available for Mitsuba rendering engine here: https://blogs.unity3d.com/2017/10/02/microfacet-based-normal-mapping-for-robust-monte-carlo-path-tracing/.
I would like to know if any progress has been made so far?
Also, I would like to help with this issue while it is useful for both sides :)

I don't think progress has been made on this topic so go ahead!
