I tried using the search function for the answer but I keep getting a page error. So I apologize if I overlooked this answer somewhere. ^_^; I absolutely love this place and I want to make more designs, but does the 3D model must be 100% quads? Would it be ok to have a few tri-polys?
Not 100% sure here, but I believe it should be all tri's. A quad is a badly defined (better, non defined ) surface.. so I'd say pure tri's is your best bet. My model didn't get accepted untill I tri'd it.. and to me that makes perfect sense.
