As you can see, I have a layer which is white with white material, and yet the polysurface doesn’t change to the appropriate color when being rendered! I have tried this in Rhino 5 and Rhino 6. I also opened some old files where I had set the color of polysurfaces no problem!
Thank you.
Do you have the geometry material assigned by “layer”? In the properties menu material tab. Seems you might have it set to assigned by object and the object might have a texture map applied.
Thanks for your reply. I fixed the issue by turning off the skylight and the sun under ‘Lights.’
