Once upon a time there was a fabulous uvw utility here
but is no longer. I used this utility all the time to export my uvws. I think it was called something like, uvwMacroUnwrap.rct or something. It was a script for 3ds Max. I lost it in a cataclysmic cascading computer crash. I might have it on cd, but my drive is down.
If anyone can find me this script, I'd say thnx!!!
