Listen, can we kidnap someone and get them to enable vue to export that vegetation? Seriously, the best way I know of to make realistic trees is with lattices. But it takes some heavy duty work. You have to make the stump, then the body, then the branches, and then if you want super realistic, make the leaf bodies in lattice. But it's render intensive, and I wouldn't recommend doing more than one tree like that in a scene unless you're prepared to render for several hours.

Talent is God's gift to you. Using it is your gift to God.
