I think that we don't need the trees breaking at all, just a bit better DM when contacting a tree. If we can live with what we have now, we would sure be able to live with what we could have then
And if tree makes a plane crash, just replace it with a burned tree texture
I just don't want the kind of forests that we have now (3 layer textures). But from what we've seen so far, forests will be forests. That's cool.
