I did read through the tutorials at AS.  Very fascinating though I didn't understand all I read.  They are using a light with IBL, a spectral light and a third special one, plus the correct shaders and similar rendering options to what I use.  I should be able to recreate similar effects with my Vue6I if I can't get it correct in Poser6, since I'm not very good with Poser.  Will just have to practice.
