Hello Brian and welcome. :) I have Bryce 4, and it was my first version of Bryce. I actually like Bryce's interface, but that's mostly because I was already used to Poser 4's interface, I guess. but I detest Bryce's material editor. Anyhow, for me, it's not an interface thing at all. The support from E-on has been very good. At any time I can email them and expect a reply fairly quickly. Vue's material editor, as well as ALL it's editors, seem far easier and more intuitive to work with-- for me, that is. Vue renders quicker. Vue trees look more real, and accept a wide variety of custom maps. Vue's trees are not static models as are Bryce's, but rather different each time, and often the differences between one maple tree (as an example) can be drastically different from another. Vue imports Poser models perfectly, as well as 3DS models. And, now that Vue 4 has volumetrics.... These are just a few of the reasons, but in a certain sense, it all relates back to "ease of use". I started out in art by doing simple pencil drawings, which slowly became more complex, then I moved up to oil painting landscapes, and then into the digital realm. So, for me, Vue was a natural, since it has such excellent landscape abilities, which I think Bryce 4 is lacking in. But I still like Bryce, only the feel is different.. Ifg i want to do something a little more "sterile", so to speak, I'll try it in Bryce. Bryce has a harder edge to it's renders, and when I want something with less of an "earthy" look, I'll use Bryce. It's all a matter of preference though, as you know.
