"No, because some are primarily modellers rather than renderers" Hmmm The only one I can think of like that off hand is Rhino. Truespace, Carrara, Shade, etc. all have powerful rendering abilities that are equal to or surpass Bryce/Vue's functionality as a renderer. Which brings me back to the notion that Vue and Bryce are both primarily landscape/outdoor scenery generators, because that's what they do most efficiently. For for other scene types like interiors, I don't see how it's any harder to create a great render in Cararra or Shade (for instance) than in Vue or Bryce. Happy Holidays. :-)
