Not windowless at all. How on earth is this concept so difficult to get right? No windows.. windowless. There's a dozen windows still. Requesting a darker room does nothing. Tiny windows does nothing, still blatantly huge. I wanted a basement woodworking workshop and blacksmithing area. Just a realistic basement with tiny high up windows on the wall. Writing only walls and various other ways to say no windows or tiny ones and it starts adding windows in the ceiling! The ceiling! This definitely gotta be a bug.
Darker doesn't work either. Scene should be dark and it's still way too bright for blacksmithing. You can't even tell the heat of the metal that one's working on.
I've tried for hours just to get either one wall to have windows or no walls to have windows. With essentially no luck at all.
