Quote - that took multiple people, including bagginsbill, years of research to do in Poser.  and Luxrender lacks SSS.  SSS is more than a lighting effect.  it blurs detail like bump and the edges of features.   i've been trying to match photos  recently and while the basic limits of the renderer is holding me up, lack of true SSS is killing me too.  and i've spent a long time working on my own fakes. 

maybe i'm completely off, but i don't expect something i would personally find satisfactory any time soon.

Cool :o). Then you can stick with Firefly.
