There is a thread in the copyright forum on this.

Basically anything you buy from Daz, Renderosity or other store , or the content included in Poser is licensed for personal or commercial use. (very rare exceptions)

That means any pictures or animations created using Poser are OK for distribution. The srtist is the copyright holder.

The figure itself, 3d geometry and joint setup remains the property of the creator and may NOT be resold, given away or put into another application from which it can be extracted.  You can use it in any 3d app you own for your own use though so applications like Vue, Carrara or Bryce are OK but thats still just creating pictures.

If you take a mesh and modify it , that makes it a derivitive work, it may be OK for your own use , but giving it away or selling it is a no-no .

There are some specific exceptions that allow people to create clothing to fit the characters but they are fairly specific and dont include use in games engines.

If you are the copyright holder to a picture that you have created, you have the right to determine who uses that picture. (the right to copy it ). So for book covers, cd covers , tee shirts , fabrics etc the copyright holder of the picture gives his consent to his pictures use, usually in exchange for some money.   The terms of that permission can be varied , for example , a book cover picture may be sold for the sole use of the book publisher. The copyright holder then cant sell it to anyone else, or it can be more open , and the picture sold to multiple businesses.
