Arcady, shader import from Poser6 is one of the new features for Vue 6 that both eF and e-on are bragging about. Also the ability to pose the poser figures right inside of vue now instead of the back and fort between 2 apps to do the adjusting. I have Poser6 and Shade8.5, so Vue6 kind of make the whole package.

Very strange you have to do all that work form poser to carrara. True,carrara does not import the shaders but if you have not used them when building in poser to begin with, carrara imports pz3,Cr2,hr2 and so on just fine.

You also must mean quality of render between carrara default render to bryce. I don't think there is anything that renders as slow as bryce. But, Free DS and Free bryce are a good start for learning.
