I have this prop of My Living Room that unfortunately seems all one piece. I cannot click on any part in it and do something with it. The roof, for instance, which blocks all those lights from illuminating the room: I cannot touch it alone to make it invisible or not there. I cannot move the piano. I can't use it like this, but there must be some way to control the separate pieces. I wrote the developer, but no answer. Can anyone here solve the enigma?
