Alright Steve, thank you. I'll be giving this a thorough checkout over the next couple of days. Since the last of the 4.03 beta's though, I haven't had any of the above problems, and I've been putting Vue through alot of tests. :) One thing I might mention is that someone pointed out to me that Vue 4 faisl all the time to do proper boolean functions on imported polygon meshes. I ran a few experiments on basic objects I made in a couple of different programs (Rhino, Amapi, Amorphium, and 3DS Max), all of which were in 3DS and OBJ format before importing. They all worked fine in Vue 3.1, but evry time I tried to do boolean differences in Vue 4 (usually just subtracting a cylinder from a cube), the object would not render at all. Strangely enough, when I tried it on a Poser mesh, the boolean subtraction worked, but in a very unusual and unpredictable way. Just FYI. It's not like it's gonna ruin my day, because when I want booleanized models I just boolean them into submission in Rhino, but I know alot of people do use the booleans to a great extent in Vue for creating things. For that matter, I don't even know what the extent of the problem is, because there's only been one person so far to bring it up. I hope this info can be of some use to you. Cheers, and thanks, Mike
