Let me add to this ... This is a test render I did of a character for V.4 that I am developing ... the IDL meshlights are commercial ones sold at another site unfortunately.  But you can see the effect.  I use them now more than I use standard lights.  I use one standard light that I turn on/off for pose/render. Character: Zera  Poser version: PP2014.  2 Fredel's Beauty dishes (meshlights).

 P.S. I do realize there are a couple seam issues, this is just for exemplify the meshlights.
