Because people have different render styles. Yes, Superfly is cool for rendering and looks very nice but it take a long time. It does not have to be ultra realistic for ever artist . Poser 4's render engine can easily go through thousands of frames in poser very fast. I would just like to be able to make nice animation with poser in a short time. With today's hardware The Poser 4 render engine would be a beast with only one computer. Hey, I just like the style and if I could some how get it on Poser 2014 by way of python it would help me tell my stories faster.
