Yep. In all views except for Physical, it sees the roof, but in that render mode, the roof and ceiling over the balcony seem to ... vanish. And for whatever reason (I removed all furniture and fittings and even rooms not connected to this one) I can't get the file size under 26 MB. I do not have (for obvious reasons) 'flat ceiling over this room', but there is definitely a roof. Maybe... raccoons have gotten in and torn up the insulation, but virtual raccoons? This software should not have those, so iam stumped.

Been working on a design, and I have a conundrum. In the great room there is a balcony. When I render the room using the "Physically Based" render, the lighting on the balcony goes bananas. For whatever reason the ceiling above the balcony (which renders just fine in other styles/techniques) seems to become transparent, leaving the balcony glaringly bright. The materials have not been altered, and the glare throws the rest of the room into a, well, take a look. Any idea what might cause this to happen? (Also: Is there a better rendering engine I can get and use? Physically based" gets me close to realistic, but...) Thanks!
