I wanted build a hotel, and wanted to use zig-zag windows (roofs) introdeced by Ms. #KateEmerald. I use this place as a restaurant and run it. 10 rooms, a spa space, a bar on the roof floor, and a restaurant. Rooms with the zig-zag windows seem to be treated as outside and dim. If someone knows the solution to make the rooms be treated as closed and properly lit, pls tell me.
