I'm building a scene along a river bed, in the northern plains of the U.S. In much of the plains, trees ans bushes are scarce, but they do grow along river beds and other bodies of water. I've had to manually place all my plants and rocks, because I can't get enough placement control with the ecosystem (though the ecosystem function is why I bought Vue6 Studio Pro. ) After many many many hours of work, it's coming along nicely, but is there an easier way? I've tried adjusting the slope and altitude controls, but it seems no matter what I do I'm not getting my plants to hug the river's edge. thanks Brian
