the problem can be about materials, because not all the materials have the same effects in your attachment(floor looks quite nice). probably most of the materials have something wrong in common, try to replace one of the materials with a simple one and give it a try. If it also have the same problem, make your window non-transparent and add a ies light inside the room, so we can see if the problem is about your window or light outside.
