If it is possible to see the whole room from the outside, then it does not make much sense to simulate shadows, because in this case it can be seen that no one is really present. But if other rooms are connected to this one, and they are not quite visible from the outside, then shadows can be created on the walls there and they can be seen from the outside. Example: The living-room is completely visible from the outside. From there, you can get to the kitchen by going through a door. What can be seen from the outside is the kitchen wall, but not the whole kitchen. In this case, HomeShadows can be aimed at the visible wall in order to simulate shadows.
