Jitter in my ver. of A:M 11.1 b I can't find it in camera, choreography... or anywhere else I think it might be and the tech ref just tells me it's visible sometimes... I have advanced checked...
And, I am rendering a scene in radiosity here's the link
and my ceiling is white (not pure white) but it renders as black, I checked the normals and some were facing the wrong way... so I flipped them... but it's still doing it.
I'll post the project tomorrow if that's the only way to get it figured out,
But in the meantime, your thoughts would be appreciated.
