Object's Material Defaults to DefaultMaterial

V-Ray V-Ray for Rhino Issues
1

On some occasions, when an object has a Vray material applied to it (rather than by layer or parent), sometimes it’ll revert to DefaultMaterial for no reason. As a result it renders grey as though no material is applied.

Unfortunately I cannot recall what triggers this bug, it’s rather unpredictable. Just want to see if others have experienced this and maybe we can get to the bottom of it.

this happens to me if I do a purge in Rhino.

Which UI method and/or command do you use to purge in rhino?

I just write purge in the command line

I was able to duplicate the issue, and will look into it more.

I was going to say it was purge in my OP, but I wasn’t entirely sure.

Thanks for confirming!
