Well for what it's worth...... I have both Vue 3.1 and Bryce 4.01. If there's one thing that I really WISH Vue had, it's a trackball-type camera like Bryce has, or rather at least the option to switch over. I DO think Vue's 4 viewport layout is an excellent idea, though, and once you get used to it, it's great. I think Bryce is a little easier to use when it comes to the EXACT placement of objects within 3D Space, as well. But, I prefer the speed and the quality of Vue renders, and what Bloodsong mentioned about the plants: See, the plants are defined by "seeds", meanning there are certain mathematically defined characteristics for the vegetations, which are based on real-world parameters--algorithims. When you "grow" a vegetation in Vue, you always get something different, but for example, a maple tree will ALWAYS look like a maple tree, but will be different from the others in your scene. On the other hand, Bryce's plants and trees are all simply 3D models in .obp (Bryce's format), and as such are always the same. I use Bryce for getting a rough idea of what kind of picture I want, due to the ease of use of it's camera, but if I had to give one up, I'd deinitely be keeping Vue! Cheers, Mike
