Another option is to carve Styrofoam with a hot wire cutter. This works well for smaller rock cuts. Takes some time if the space to cover is large. Results in a light rock face, which in my case, is easily removable to access the track and hidden wiring. I have rock moulds, but have never used them. I am avoiding the mess or working with plaster. Nothing wrong with plaster, I am just avoiding it for now.
