- darkpore 12y agoRather ironically, Arnold's standard shader still has bugs meaning its Cook-Torrance microfacet model isn't completely energy conserving at glancing angles...
- damon_c 12y agoInteresting. It's been around long enough you'd think they would have worked out those details. I just linked it because I felt it gave the clearest explanation of the concept.
