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!
