Interesting thread. I'm a dedicated B4 user, but my time and machine power are both limited, so the faster renderer in Vue 4 is tempting, too, even if the interface is less appealing than that of Bryce. The veggie generator and better lighting/rendering, including soft shadows are (AFAIK) the main selling points of B5. If anyone would offer a few comments like the above on rendering times, bugs (if any) and, well, whatever else, I'd appreciate it. Thanx in advance.
