Snoopy I'm not sure 100%, but I think you can use without problem, I don't remenber well but I read about this soft and comments about download hundreds of models do it whit Spore, and another point, it's if have an exporter for any 3d tool , I think they win money whit 3D artist,... in the forum I read some 3D artist it's using for his works.
I think I'm wrong whit the soft, I try a lot of things for export the model and doens't works, I think you need the Spore, the game (have a lof of more of capabilities for make monsters) and then whit this it's possible export.. Not it's too much expensive about 20€
I will comment something in next moths, I buy because usind whit Coat 3D, Zbrush or another poligonal 3D tool, you can do a lot of graphics in 2D or 3D and very very faster.
