I Michael, I have a little .3dm v4 file related problem.
I try Rhino 4 for texture and render a moi shape. Rhino ask me to save in v4 because v3 it's obsolete. I can open it again with moi, but if I change something and save it I lose all the material information. It's going to change with the next beta or we have to take care about this and don't save back in moi?

Thanks
Luca
