"As I use poseworks python scripts, the Unimesh realism kit and several shaders, looks liek I'll stick with Poser6 for now." That's probably a sound approach. If you want/need to look at a different rendering solution, then probably Vue or Carrara would be better. I think one or both of those is supposed to have some level of support for Poser 6 materials and I'd bet that Shade does or soon will. One advantage of bitmaps, they're portable to virtually every renderer :-)
