I'm doing the dino DVD and until now there have ben no problems. Now I'm stuck. HELP... when I convert from poly's to sub's something really weir happens.... first it tell me that I need to do a nominal clean up. I do that. Then do the conversion and things get messed up. Pieces are missing, and there are holes were things used to be. It got to the point that I just deleted all the problem areas and redid them. There is gotta be a better way... right? Any suggestions would be appreciated. Thanks Rob
