Another thing that I noticed about Autodesk VIZ when doing a special project is that the rendering quality was pretty poor at our room. Everything was so bloody bright and barely gave off any detail that the skin was supposed to show.
But yeah. As ebmonon said, just use AD2K5 for building/modeling you items and then transfer the file to 3D Studio MAX.
But going back to the first (no pun intended) question...well...lets just say...not legally...
