I have modeled a section of a wall. That section can be arrayed so that it looks like one seamless wall. I have an array modifier on the wall. I also have am uneven terrain. I have a curve that guides the wall. I have shrinkwrapped the curve so that it sits on the terrain. I expect the the wall to be on the terrain. Instead the wall is hovering in the air although the curve is doing what I expect it to do.
