I've been doing some posting in Japanese (yeah what a show-off :-P ), and maybe Netscape is inserting some weird encoding in the message or something. I've attempted to reset what I've done, hope this message is respondable-to. I'll have a look at your monstrous polynomials. If I can use an approximation they'll probably help. But maybe I don't need to shrink my normals to unit length... I think I'll try again with just one of my questions in the hopes that it'll save me work. (Let me state that the reason I'm asking this question and not just trying it out for myself is that I have non-lit TMDs constructed on the fly working properly, but my lit polys are invisible. I'm trying to debug them, and am trying to eliminate potential sources of the problem): Question: Do normals in TMDs have to be of unit length, or will any old normal do? Does anyone know? - nick
