Three minutes rendering time start to finish in P5, using the P4 renderer. :) Of course, this is with one figure and no surrounding scene. The more objects you add to reflect light and make shadows, the longer the render is going to take, of course.

Though with the number of "sculpting" shadow lights created in the EC set, I was also getting very nice renders with the shadow render option turned off entirely. Here is my little lady from the start of the thread again but rendered with no shadows this time. I think she still looks pretty good, and this render (P4, anti-alias on, shadows off) took about forty-five seconds.
