Sephyn, you're obviously not a lawyer. Don't play one on the Internet. You've already admitted in a previous thread that you're using an illegal copy of Poser. Don't make it worse by asserting your right to steal other artists' work.

You may be confused because the Marketplace is full of characters for Vicky 3, etc. But those do not include any original mesh. They are morphs or dial settings; you must own Vicky 3 to use them.

There are ways to distribute modified meshes. Free programs like RTEncoder "lock" the file, unless you have the original mesh on your hard drive. And there are "texture base packs" available in the Marketplace and Free Stuff, that specifically allow you to modify and redistribute - meant to give you a head start in creating your own texture.

Sorry if it seems like we're piling on here, but we take copyright very seriously. You might want to read a few of the longer threads in the Copyright Forum, just so you know where people are coming from.
