I noticed that using your (amazing) box mapping and preview material components leads to a weird effect when looking at geometry in the rhino viewport with “rendered view” on. Namely, the shadows from existing geometry in Rhino overlay the textured elements coming from GH.
I tested if it’s my render settings, reset the view settings, tried VRay as renderer, and tried a normal “custom preview” component with a material from within Rhino. It seems to come specifically from your component.
Ever encountered that problem?
