It's not like they are completely different. I quote an article from Blenderartists.org on that topic (without any guarantee that this is true): "At low roughnesses there is hardly any difference between GGX and GGX Multiscatter. At high roughness, GGX looses energy - it becomes darker at glancing edges where it should still remain fully white. GGX multiscatter behaves much better and remains nearly perfect white." | |
| Mar 6, 2023 at 15:34 | comment | added | Red | Thank you for this somehow I'm starting to understand the light scatter from this two node. But how can I use the MULTISCATTER GGX? When I changed my microfacet from GGX to Multiscatter, Suzanne image still looks the same as that when it was in GGX. | |
