Hi Dave, I don't own Bryce yet, but I have played around with it a bit. I think Bryce may have a more comprehensive sky generator. Moons and Suns in Vue take more work. On the other hand, Vue plants are "grown" individually. If you want a 3 armed cactus or a 1 armed cactus, just keep hitting the tree button till you get one you like. Same with all the other plants. Why not check out the Vue 2 demo? It doesn't have all the features of Vue 3, but you can get a basic idea. Hope this helps. Gail
