There's some stuff here, there is some at www.contentparadise.com as well, even DAz has a little, but most is at C3D indeed. Since they've opened that store, Vue content at other stores is getting less and less. If you find stuff, I'd like to know it as well, since I'm also having a hard time find items outside of C3D.

Artwork and 3DToons items, create the perfect place for you toon and other figures!

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
