Im not bothered by 3DS or Obj or even DFX. What realy bothers me is the fact that a majority of the files do not work with poser 4 even if thats what they are posted as. When you read the readme, It doesnt say any other files are required. Not to mention ,,,the false covers. You download whats supposed to be a prop. When you open the file, its a texture. Thats what makes Buying in the store scary for me. Im not gonna spend 20 buks on what I would think is a prop, to find out its just a texture. I can just imagine how much the texture for that basketball costs :).
