Dang How in the world can you say that PP4 is better than P5. More stable and faster yes But!!! All you have to do is look at the the renders that people submit that are not post processed. The ones in P5 blow the P4 cartoony rendered looking characters away. When I upgraded to P5 my mouth dropped open when I saw my first firefly render I have to admit I am not to happy with some of bug problems that have occured and the slownest of its fabulous renders. But its hard for me to look at a PP 4 rendered character and take it seriously. The only time a PP4 render is going to look as good is if a lot of highly skilled artistry performed a significant amount of of post processing on it. Or someone used a expensive high end program to render it with. If CL can stabilize this product it is by far the best value and most powerful product in anything near its price range.
