I use Poser.  I save all my textures, complete with bump, transparency, and specularity settings, to my Bryce material library.  I export as an .OBJ file into Bryce.  Since transparency and bump settings don't transfer, all I have to do is select (for instance) the body of a figure and click on the material in Bryce.
Usually, I import into Bryce 4 first, that way each body part is separate.  That way I can adjust patterns and textures on individual parts as needed, e.g. aligning fabric patterns or making a figure's feet and shins look wet, or only their hands dirty.
