I save my most used Poser textures as Bryce materials complete with bump, transparency,  and specularity settings.  I made special folders for People textures which has subfolders for skins, eyes, hair, and clothing.  That way, when I import my Poser .objs and Bryce asks me to find the materials, I just skip it all.  The object imports as a blank, white figure.  Then I just apply my saved Poser materials from the Bryce libraries I made.

This way, you find the materials once, set the bump, transparency, specularity perfectly, save it, and you never have to go searching through your Poser texture files for it again.
