I have a room scene. Light sphere outside lighting it. I have GI on. It's looking great. Plenty of light in the room. I have the windows turned off though. When I turn them on the room goes almost completely black. It's almost as if the light isn't passing through them even though the geometry is extremely thin and the material couldn't be simpler (100% refraction and 100% non-glossy frenel reflections).
Can anyone think of a reason why un-hiding the geometry from the windows would seemingly block all light? I can still see the geometry outside the windows, so the transparency seems to be still working it just seems not to be allowing light to pass through.
Please advise.
Thanks!
