Quote - Sorry getting this late into the discussion with the polys :)
I have imported many of the new models (mainly the adult trees) and saved them as .vob, no problems with the polygon count. (I've done so many times before, both with XFrog and Onyxtree hi-poly models).
I prefer the 3ds export, and don't weld the model right away, maybe some tweaking is needed. E.g. the tree species with the roots are awkward for use with ecosystems (they need to be "sunk" into the ground), so I "boolean away" most of the root object (it can also be deleted).
Also, I work a lot on the textures.

Better late than never, Lars.

...if the truth be told, I wasn't planning on purchasing the software so I was looking for a quick & dirty way of salvaging as much as I can before the expiration period is up.  I hate to even admit this as I think it's an insult to xFrog who has been so gracious and given us this wonderful gift of 100 free plants...with variations to boot.

But who knows.  Downloading the demo may have the desired result from me - seems like a really neat program.
