Thank you again for the precious information Touchwood :)

By the way I have another question about Blender. WHen I use materials I select "use nodes" but in the node editor there are no nodes except for rendering. Is there a way to make the nodes corresponding to the scene materials show up in the editor?

 

To Paul: I have yet to try wing3d. Which one do you prefer? how good does it stand compared to Poser?
