yeah it seemed a bit high to me too, but the trees look nice... great background pieces. THey do have an option to control the number of points on the pase of the tree and the subdivisions up the tree.
edit:
And the ability to plug in your own textures makes it good for creating pretty original trees too... i even made wierd looking shrub thing....
Edit: again:LOL
This really takes the legg work out of creating some of the more mundane filler things... i like this alot. (Though i havent had a chance to test the export quality of any of the trees i made..)
