Crash on Paste, Related To Material

In the attached file, there are two identical polysurfaces, one is blue and one is orange. The blue has the default material assigned, the orange has a material called “Masonry sandstone light brown”. Both are on the same layer. When I copy and paste the orange poly surface, Rhino crashes every time. Copy and paste works properly with the blue poly surface with the default material. System info attached.

Hi Kaleb,

I tried in a slightly older version of Rhino WIP and could not repeat. The latest WIP does crash. Do you need an older WIP until this gets resolved?

Thanks for reporting RH-94918 Crash on Paste, Related To Material

Hi Japhy,

Thanks for looking into this. I’m able to work around it for now but an older WIP would be good to have access to, just in case.
