I like grouper and metalfixer, both are very useful. I have, however, gotten into the habit of exporting from poser without textures in the first place. Makes for quicker loading, none of the annoying finding of textures you speak of, and I'll be doing extensive rework of the textures anyway...straight from poser material settings look like crap in bryce. I use grouper to strip all the maps if there are any, import the model and turn it a nice neutral mat with the ambiance and diffuse values already set. From there I assign families and load the image map for each one(and tweek) as I go. That's just the way I like to do it....
