Wow, those are some interesting results. So far, I've only been comparing render times within C4d, using the different mapping options. On my machine, Pro renders slower than d'Esprit (when it should be faster!), so I didn't bother comparing C4d to Pro, speed wise. I'm working on a somewhat complex scene in Pro right now. Should be very interesting to see what happens when I export it to C4d. The tough part about this kind of comparison is that the mapping will be different.. no way around that. One thing I really like about Vue, is that there are so many options for render quality, like aa. It's hard to match that up with the few options in C4d.
