Regrettably, Rhino Version 8 Doesn’t seem much better at handling large materials than V7 was. : (
After a certain point, it becomes difficult not to crash Rhino 3D, with a single mouseclick.
My current system is a AMD 3900x, 64GB RAM, RTX 4070.
I haven’t checked it recently, but Rhino used to keep temp files for it’s texture handing, which is a big no.
