I use poser characters for characters in Bryce. I feel that once they are imported into Bryce it becomes a Bryce render. Poser seems to me to be what I would term a painting or staining type or renderer. Lights apply colors like inks to a region of the image. Specularity is at a minimum and true reflection is non existant in poser 4. By contrast, Bryce actually deals with rays of light. When I import a poser character I usually replace all the metals with Bryce metals. I occasionally use the poser texture underneath as a bump map. I use variations of Bryce tile procedurals for cloth on much of the clothing. Bryce glass replaces the outer eyeball in Vicki. Usually less than half the original poser textures are used on my final Bryce render. Once I'm done with the unique textures only possible in Bryce I have a render that would be quite different in poser. I never bought bryce as a modeler, I bought it to render from Rhino and Poser. If it was meant to be a stand alone program they never would have set it up to import models, or images into the terrain editor or the materials editor.
