Vue6 will import the Poser6 shaders, something to think about. I will be upgrading at the end of the week to V5I and get the V6I  when it comes out.

Bryce is OK if you like DazStudio but a complete pain in the, you know what, to use with Poser.

I have Carrara5Pro. Works very well with Poser imports and can model fairly well. Not as good as a modeling app, more of a light weight modeler. Runs circles around Bryce for rendering, but then, what doesn't.
