Well, I'd like to say that I found this thread interesting and useful for consideration of potential renderer choices. Just thinking out loud here, but would it be worth having specific threads for settings in different renderers? One for Poser scenes in Lux, one for Poser scenes in Vue... the main thing holding me back is a complete lack of understanding regarding the materials settings, not the software itself. Reality offers some decent support for Luxrender, but trying to find specific information on getting V4 in Vue to look like V4 in Poser is very hard.

Just thinking out loud, but as I've had only limited success in importing scenes into Vue or Carrara, and limited success with renders in Lux, I haven't invested the time into them (given the wealth of information available here regarding Firefly). From a personal point of view, my main issue with Poser is not being able to do large outdoor scenes with plants. Carrara and Vue can, but then the people look completely different.
