Important problem for the lumen developers @Krzysztof.N @Daniel_Wright
Tested out the LoftOffice content pack for a project, and I discovered that it’s breaking lumen GI; in a radiometrically simple scene with nearby puncual lighting, there was an inordinate amount of noise. My only guess is that the high-frequency herringbone ribs on the wall are creating depth discontinuities that are stopping the screenprobegather from sharing samples spacially, but that’s only a guess:
Upon enabling the screenprobegather visualization mode, I noticed a strange ball of short hits marked red, which I have never seen before.
The normals also look quite strange, but that could be the geometry itself.
In terms of real-world workflow, this herringbone geometry is almost a perfect use case for POM if the stepped effect was absolutely required, but it seemed like a problematic issue nonetheless. If you consider this inappropriate content to be @ ing you over, please let me know and I will gladly stop.
