I'm really impressed by these fine image examples. Even when it's clear that the artists have only just scratched the surface. In regards to GI, Radiosity and HDRI render times, I think you have to expect some 'jump' in render times.(As opposed to what you might be used to) Sure, everybody loves to be able to render an image very quickly, but if you want to take advantage of HDRI, radios.., & GI, expect to wait on rendering for a little while longer. With any 3d package, you just can't escape some long render times. What I'm saying, is I wouldn't expect Vue 5 to work miracles when it comes to rendering times, just as I wouldn't expect the same in other 3d packages either. When you produce such work like this yourself, you'll understand more about the unavoidable longer render times. Anyway,(I'm ranting a bit) the results you'll produce are definately worth it.
