For the last couple of years or so, all my renders are from poser to carrara, Ill never go back to P4 rendering. I use the texture mapping that is imported from Transposer, but Ill tweek a lot of them. Most of my scenes usually have one or two spots or a distant (for the sun) and indirect lighting. Sometimes Ill create a plane opposite the figure to bounce some of the lighting back on to the subject. Just be ready for some longer, but higher quality renders.
Regards,
