Vue also has another major thing over Bryce, but it's more of a technical thing I'd say, and not necessarily an advantage: The inteface. Vue 4 has a 4 viewport setup, in addition to a trackball camera. Plus, Vue's "world browser", which is much like Windows Explorer makes grouping objects and assigning materials, creating booleans, etc., etc., nuch easier than Bryce's setup. Also, Vue's Material Editor is very intuitive and easy to learn, so you can spend more time making pictures, and less time learning a difficult interface.
