@pumpher @littlepleasures Much obliged it, for the detailed answers. Iam tinkering with these PBR shaders a lot, and I think this script is a must, especially when rendering some of heaviers characters, like characters from Bluejaunte. https://zonegfx.com/iray-memory-assistant/
No wonder my render time is alway so long, bluejaunte's characters base textures alone took up 5gb and I keep adding more and more detailed map to them "_"
