I download last WIP, it do not crash… it opens… but when opening material panel, it crashes.
If it is a new file, panel is opening without materials, but when clicking on + it crashes.
Rhino crash.txt (146.6 KB)
It seem to be the panel which make it crashes, because if opening a file with a render viewport and a material previously created and applied (into V6), the render viewport looks good…and it is only when opening the material panel that it crashes
Hope it could helps you…
