Erlik, I bet you will be able to use existing poser content. not sure about a library of parts, but might be iffy in the copyright area as the original creators of the mesh for the parts would have the copyright...but would they have the copyright on the final assembly? exporting I would say probably. Daz is known for wanting the community to grow, not throttle us with restrictions on our creativity. hmmm...gravity.....okay now that one got me thinking about the implementation...gotta start going through the source for a few games with gravity...
