I am a Brycer. I have not used Vue at all, But one thing that bugs me about bryce is the render times and the HARD SHADOWS IT CREATES... other then that its a dam good program. I just wish they could make the lighting effects much more realistic. It took me 6 days to make soft shadows useing radil lights on a complex sence. Maybe they can add it to the Effect Antialiasing options. Radiosity and Causics are a problem too... its too much work to simulate it...
