This question about copyrights is often asked. The way we deal with 3rd-party characters for Poser is that the artist sends us a PZ2 file that injects the morphs the artist has created. Then we apply those morphs to the appropriate character. (We have already purchased nearly *every* conceivable base character set that is available.) Other 3D programs work in other ways.
This is a technical detail that we will work out with each artist to ensure they transfer files in a way that respects and preserves the copyrights of all parties.
Our primary focus is on stimulating interest in 3D characters, and creating a venue for artists to show off their works, and form relations with our favorite artists, and providing prizes as incentives to participate.
