Hi
I have already sent this problem to iToo but having the issue with Vray I wanted to share here too
The issue is that when editing ForestPack, Max crashes while on IPR with Override Material, I think this its an specific issue because I could only reproduce it with a model of iToo using translucency materials
This error was caused because of Vray2sidedMtl, but if I change the material using translucency with ThinWalled, the error its on the core
This only happens with Mtl Override activated, if not, theres no issue at all.

Mind if you provide a simple example scene?

Thanks for the provided scene. I’ve managed to reproduce the crash on a simple scene. It seems to be related to the “Preserve original” options of the Override Material functionality and the particular shading structure of the FP object. I’ve logged it (internal bug-tracker id: VMAX-14066) for dev investigation.
