I own Vue 4 Pro and it is the best landscaping program I have ever used - this software deserves a forum without question.
I think programs like Vue, Poser, Bryce and so forth get a lot of bad press from the pros because there is so much trash floating around from people just using pure Bryce - mountain, tree, sky, water, done. Bryce is a starter program for people in 3D, I think - it gets your hands dirty but it isn’t professional at all and should be avoided in most cases… that is not the case with Vue. Vue is basically the advanced version of Bryce - and you can really get great results with it while working in combination with another 3D package like 3D Studio or Maya - especially with Vue Pro and its export features. I have no real excuse for Poser, haha - although I do use it now and again to cook up a quick model to use as a shadow in my graphic design projects… it really has no place in professional 3D, IMO.
If you haven’t tried Vue - give it a shot, http://www.e-onsoftware.com has a trial version for d/l - it has HDRI features that get really nice results.
