First, I'm looking to see any scenes rendered in Lightwave (or some other 3D app) that V5I exports whole scenes to. Secondly, I'm looking for an animation done with V5I by importing animated Poser scenes. I'm still really torn between doing the final project in Lightwave or V5I. The ecosystem looks amazing, but I need real hair (not imported Poser noodle hair) and particles like dust and ash. Both apps have their attractors.

Sounds like composition is about to be your new best friend :) That's how studios do it, very rarely is a scene done entirely in one camera on one app. Each element is rendered out to be composited later, even if those elements are generated using the same program. You could never do as good a job with landscapes as Vue does in Lightwave, even with a scene export. Likewise you can't get good character animation in Vue, use each for its own uses.

On a side not, the ecosystems do not appear to be exportable as part of the scene (at least that's what I'd seen in another thread), which isn't all that surprising if it really is a new technology that is unique to Vue. So even if you were going to use Vue for the ecosystems you'd still have to do like DMM said and render the animation directly in Vue and then composite.
