I'm a dabbler, so can't really post a proper opinion. But... I have Bryce 3.3 (no tree lab), Vue5i and Poser 6. For images which don't need much vegetation (interiors, for example), I can use either. Both work well, but Vue seems to need a bit more setting up than Bryce does. But then I'm still learning Vue (and Bryce, if it comes to that). I also have a reasonably fast machine and 2 gig of memory (which helps a lot). At present, I find Vue gives much more realistic (outdoor) images (especially as I get better at using the Vue function editor) than Bryce and Vue can import Poser scenes much more easily. However, Bryce seems to be much quicker and easier to use for simple scenes, and is a lot cheaper. And it's easier (for me) to edit scenes in Bryce than in Vue. Vue is slow (due to the way it updates the 4-panel views). I'm gradually getting to know Vue and liking it more and more as I get used to it. But it does need a beefy machine to work well. But I still use Bryce. In general, I'd go with the highest version of Vue that you can afford, dropping back into Bryce for simpler scenes. (No tar/feather brush applied!) Cheers, Diolma
