ok, it's updated to have color, bump, and specular nodes set to the left of the main Poser Surface and labeled for easy access.  i also added previews (no more shrugging man).  and, well, the shader is very different, too, actually.  better, imho.  i'm still working on the metallics.

let me know if there's any problem getting to it, or using it.  oh!  and even though the white material's color node previews black, it makes a white shader because it's actually a hyper white.  don't ask me why it looks black.
