Quote - Yes I exported the first one fro xfrog demo. Soy plant.
Both as obj and 3ds.
Imported both into vue. the obj came out sideways and for reasons I've not yet figured out looks worse to me than 3ds.

I did not check poly count. But if poly count was high I would then only use a few up front.
I only had one on screen at a time and was able to grab and move it in real time no lag.

I'm working now but I might be able to check in tonight for further questions.

Yes, mine came in sideways as well.  Total polygon count is 171,389 of the plant I'm using. 

I think I'm coming to the conclusion that the demo version of XfrogTUNE does not let you save out a reduced polygon model.  I've just completed the tutorial which is included with XfrogTUNE and in the end, where the model is saved, nothing happens for me. 

Lars - what is your experience?  Maybe you have a full version of the Xfrog software?
