(I think!) After updating Rhino 6 my shading no longer works:
(examples of surface and mesh from various models.)
Until update, everything working perfectly. Rendered viewport still works, but the shading in Ghost is also corrupt. I was using a lot of memory in GH when I noticed it,
I have a Rhino 7 license, and the shading there is still OK, but it wants me to update which I won’t.
Drivers are up to date. The laptop I have here isn’t the best, but it was working fine. What would cause this? Do you have the old build available??
