Hi, I figured it out by re reading the instructions, but it was purely by accident that I got the Brush function to start painting trees on the map. After I dragged and dropped the selection of vegetation in the settings box, I raised the density settings on the tree brush for the trees I wanted to put down on the map, and wala! Trees! I tried it with a few different vegetation and tree selections from the editor's list and they all worked. If you choose a tree or plant to use the tree brush to put on your map check your density settings for your selection if your not seeing any thing. Also size might affect how many trees the tree brush can "paint" at one time. Thanks, Shaun
