I've always used the Firefly rendering engine within Poser--I've found the default settings to be useless, but I get good results with a little playing around. POV-Ray does lovely renders, but I've never tried to export from Poser to POV-Ray (and I find working in POV-Ray to be a bit of a pain anyway). Laurie, that is a very nice image!
