Prevent light from lighting inside a closed room? I've got a problem with lighting. I don't want lights that gets through edges :/ I have closed room with floor, ceiling and walls. Point light object is created upper ceiling. And light gets inside the room but it should not. How to fix this? Room should be dark but is bright because of light object :/
You have to go to the lamps properties > "lamp icon" > "Shadow" > enable "Ray Shadow" to get this fixed:
