It would be nice to have the option on either a room, or object to mask object graphics to only the room in which an object is placed. I am planning motion sensor placements, so I made custom objects with the range of the motion sensors, but when I place them in the house, it looks like the image I attached, where the ranges overlap across rooms, even though the range stops at the bounds of the room walls. I would be looking into areas where there is no color, but that is hard when out-of range sensors also have color.
