I have bryce 4 and vue 3.1 and I uninstalled bryce once I got vue, but when I build a new system I'll probably start using it again. For me it boils down to a few things: 1. I hate the kai/metacreations wacko interface. I also hate truespace's interface--anything that doesn't have menus, a toolbar, numerical values, and standard selection behavior is my enemy. Basically I started with photoshop and I expect things to behave like photoshop. However some folks who are new to computers prefer these widgety graphical interfaces. If you think poser has an easy, intuitive interface you'll probably also like bryce's; I find it nearly impossible and find vue's very intuitive--although I too would prefer a trackball camera. 2. how much power does your computer have? In my experience bryce renders much more slowly than vue, but I have a pII450 w/256 ram. 3. how "hard" do you like your renders? Getting a hard glassy render is tough in vue, you have to screw around with lighting a lot. Getting anything other than a hard glassy render is tough in bryce, but I've seen it done. I personally prefer a hard render but am happy with vue anyway. 4. do you love greenery? Vue's plant generation is great, although sadly lacking in "growth-algorithm" flowers (the bonnys are okay as long as you get them from the right angle, but their centers are completely screwy seen from underneath--what a disappointment that was!). Guitta has done great things with plant studio and vue, but in theory you could also do that with bryce, so it's really the trees and grasses and green plants that make the difference. Bryce has greens too but they're static models so it's harder to get random-looking growth. Mary
