1. Open Editor (any project)
   2. Create new landscape
   3. Create new blueprint
   4. In construction script, create attached image (Xmax set to 100), compile, save, close
   5. Place copy of blueprint into level, move it around.
   6. Move camera under landscape, look for red traces under landscape denoting no hit registered
