Thanks for the response. Ill have to check a few out. Demo first of course. You cant keep on sending out on different applications. Im just wondering though. Which version works o.k. & is the .obj a plug in or standard. As my experiences with Amapi shows it makes a difference. I havent found it very successful in going in & out of other progs like UV Mapper in sorting out the vertices numbers changing. Dont understand why they should change.
