What I was thinking was that you could only edit Vue scenes (including trees) in Vue, but integrate them essentially at render time into (for example) LightWave. You'd need standins or something for trees, not the trees themselves. This method works pretty well for a Shave and a Haircut, only SaaH is just one product; you don't have to buy a separate plugin. It would amount to a souped up version of Ozone that allows you to import entire Vue scenes rather than just their terrain, and edit the atmospheres and such inside of LW via Ozone. That would make it 2 products in the $250 range each, which would have it priced pretty much competitively with the average LightWave plugin.
