Wow, I must say I'm disappointed. I've been looking at preview renders and the sort since they've shown up, and while initially I thought it was neat, I think i'm just underwhelmed by the new renderer after seeing these comparisons. I, as a regular person in this as a hobby, don't see much difference in the renders. Sure, a little bit of light or shadow here, and maybe the dynamic hair (which I find to be unattractive and unnatural looking) a little fuller, but I don't think it's worth all of the extra time. If there was a large, visible difference in quality (aside from the apparent render bugs), I may think a little differently, but I'm just thinking that maybe it's not such a bad thing that I don't have the money for it now anyway. I'll keep lurking in the shadows, but with the other bugs and the mediocre new render engine, I think I'll be waiting longer than I intended now.
