I think the thing like Modo's unwrap tool would be 3ds max's pelt mapping. I dont know if funky bunnies said it, but I might as well see that. I am running maya 6.5 so the best things to do with that would to try to find the correct mapping method and try to just relax all uvs that overlap... usually its enough. Sometimes it isnt. Anyway, this is what I have to say.

Btw funky bunnies, i cant find the pelt mapping on the demo of 3ds max 8, is it even on there?
