I also have Bryce 5 and Vue 3.1. I'm still waiting for Vue 4 to make it to my door as I just ordered it last week, but I was a Vue 4 beta tester so I know exactly how it works. I've used both and I have to say, as much as some of the bugs in Vue agravate me, Vue is BY FAR the easier of the two to learn and use. One of the things that nagged me about Bryce was that kludgy interface where you are always having to constantly switch back and forth between views. I'll only mention that I detest (strongest word I could think of) Bryce's material editor, because if I really got rolling I could go on for too long about how much I hate it. Procedural material creation in Vue is an absolute dream. Also, Vue's renders have an almost painterly look to them as opposed to earlier versions of Bryce, but you can achieve a similar look in Bryce 5 now that it can do soft shadows, blurred reflections and the like. Now in Bryce's defense (enough of that snickering from the back row!)...some folks genuinely like it's interface. It really confuses some folks to see 4 different views at once. And Bryce 5's tree lab is cool and the metaballs are really neat. And even with all Bryce's other shortcomings (only in my opinion of course), I have always really dug it's terrain editor :). Like most folks have already said, download both demos and try them out for a few days. You'll be better able to make up your mind which is the best for you. (But also keep in mind that Vue is $100 cheaper and Bryce is owned by Corel - need I say more? Not exactly the best company known for it's support...LOL). Laurie
