I used Bryce 5 for years.  Had the DAZ Studio bridge for it when I used to use DAZ Studio back in the day.  Never could figured out its material editor.  But I never looked at the manual since I could figure out everything else in Bryce.  I still love its terrain editor for making game maps with.  But Vue gives me better realtime previewing and the top/side/front views of scenes while working in it.

I don't export from Vue.  My models are all imported into Vue.  Vue is the stopping point for most of my projects.

Best way to learn Vue is to open the sample scenes and poke around in them to see how objects at labeled, grouped, textured, hidden or not, positioned in a scene, etc.  Then start looking at how the clouds are set in the scene and what parameters they use.  Then look at the light sources to see what kinds of lights are in the scene and how they are positioned and aimed and things.  Then look at the environment as far as how lighting will affect it and how the render will act on it.  All my Vue scens use the GR lighting (best) and I use User settings for my rendering (also set on highest for object AA). 

Check out the Vue gallery until you see a render you like.  Then find out how it was done.  That's what I do.  If you don't find a Vue render that you like at all, then Vue won't be your thing.  Both of my brothers are color-blind and so are not interested at all in rendering as a hobby.  They still play all the video games though.

BTW, I still use my other 3D programs from time to time that can do things easier than Vue can.  But I pretty much render only in Vue because of its outdoor environment sky and lighting.
