Well, I'm a new P5 owner; also have P4Pro. I installed P5 on the same machine, but on a different HDD. I just gotta say, that Firefly renderer is pretty good, compared to straight P4 rendering. I have a Millenium figure with some velvet material. I loaded a P4 version straight into Vue, then an OBJ version that came out of P5, into the same scene. The velvet, plus expected fabric wrinkles along the legs came out INCREDIBLE! when compared to the P4 figure, right alongside of it, in the scene. You couldn't tell what kind of material it was, and it just came across as a solid blob of red, in P4, with maybe a hint of the folds (or wrinkles). One strange side effect, a small portion of the chest showed through the P5 version, which was not the case in the P4 version. And this was a conforming clothing item from Renderosity. Easily fixed, but still showing the difference in "interpretation" - for want of a better word, between the 2 versions. One P.I.T.A. problem with the P5 OBJ in Vue though: It asked me where all those materials were, and I had to navigate for each one. I gotta take care of that. But maybe the upcoming Vue update will erase the need to do that. I sure wish the upcoming Vue update would work with the Materials Room settings, though. Those are nice! Overdue, in fact. Norm
