The Firefly Render engine in P5 is really the only things a like about it. It produces much more realistic skin tones than the P4 rendering engine. If you check out the Poser Forum there are a lot of examples online comparing the engines side by side. I can't wait for Daz Studio, which will be free! Then you will buy the modules to enhance it depending on what you intend to do with the application. Let's hope for better lighting and a good renderer.
