I’ve been testing Lands Design 6 on Rhino 9 and I quickly noticed that plants look pixelated in Rendered display mode. After some tests, it seems to have to do with the “Use advanced GPU lighting” setting, because when I disable it textures no longer look pixelated. However they still show some transparency artifacts. Nothing of this happens in Rhino 8, with or without enabling that setting.
i was able to repeat this using the textures out of your file, thanks for reporting.. RH-98139 It’s the transparency mask that’s failing rather than filtering, with advanced GPU lighting on the masked areas fill in dark instead of cutting out, and since that happens around every leaf and twig it reads as pixelation. Rhino 8 is correct here at its Rendered defaults.
