Yeah v-ray is really quick I don't use Bryce much these days, as I can do the same things and render them in 1/10th of the time in another program. You can't really model in Bryce either, other than boolean and resizing. I'm much more into Blender and C4D, and fractals once in a while
Wow this is pretty cool, I really like everything, except the goldish color, but thats just me. Ive been doing alot of stuff like this as of late but a little more abstract, you should check my gallery out if you got some time I think youd like it.
