I'm having an issue in CAW using retaining walls which border up against water. When I try to level the terrain so that all you can see outside is the wall, then I'm left with holes on the inside of the wall. And if I smooth that out, the terrain shows up on the outside again. It's maddening. I must be doing something wrong. Any advice would be appreciated. I thought about adding plants on the inside to disguise it, and non-routing paint to keep sims away, but I might be asking for trouble. My other thought is since the walls are "invisible" from the inside ... is it actually okay, but I'm seeing a hole in CAW?
