It's a better product for the same functions as P4 and runs faster with a better render BUT the text files MUST be better managed (use CorrectReference) OR go nuts not so quietly. The first render of a scene takes about as long as P4, but subsequent renders go like a bat out of hell ... and that's with the firefly renderer with shadows. I don't use the face room, or cloth room ... a bit over my tolerance level. The ability to stack and rack the library is a very big Plus, as I have a very large library of stuff. Like the P-38, the widow maker of WW2, it's initial entry into service was a bit rough ... but I think that it's spiffy.
