The Carrara rendering is much much much better than Firefly the Carrara rendering engine will actually give you photorealistic rendering much like the more expensive rendering engines out there...its just amazing to see something like V4 rendered in firefly and it comes out like bad anime and in Carrara she looks amazingly real.  I got Carrara just for the rendering its that good..plus it will easily import poser 6 scenes along with the animations.    It does not wash socks but it does allow you to get WWE PPVs.
