Use some loopix trees and get you some code to make them sway. Those resources are free, and they look really good. Speedtree is very limiting in the fact that you cannot alter the trees very much at all. The trees themselves are good but I have seen tree models just as good in many games. If you or someone you know can model you could make better trees, cause with speedtree your paying more for the cool code than you are for their tree library. GS out.
