Well, I flipped the normals and now I have the foliage on the other side of the bridge. One tree sticks out on the road a little. I'm trying to use the paint tool to knock it out, but the paint brush cursor never appears and nothing happens. The paint cursor does not show up in top (and other) viewports. When I go to an ortho view and tilt the terrain nearly on edge, I see the cursor leaving blobs of orange paint area circles here and there, but all over the viewport and not the actual surface. Treewise, nothing much happens.
