. This is a free 3d modeling program by discreet, I think they are the ones that make 3dsmax. I could be wrong since I have no idea what I'm talking about. The other link is a script for Gmax (the free program) that will import .mdl/.mdx's into the program for editing and out for use in the game. The link is dead though. If it ever works, you should give it a try. Although, I doubt it works for Kotor models. I guess we'll never know since the link doesn't work.
