Does it go away when you turn off your ceiling? Is it always at the same spot on the screen, or does the effect move when you pan around?
If so, then most likely the problem is caused by a ceiling plane that's not thick enough!
Does anyone has the issue like the right down side of the picture attached? This is a part of a rendering in a closed meeting room where no sunlight comes in, but it got rendered, there will be a "rainbow like" light. Anyone knows what causes this?
Thanks!
Please kindly have a look at the reply above actually, it does look like a light leak problem.

Thanks for your reply!
It does go away when I turn off the ceiling and the effect moves or even disappears when I pan around. I have tried thicken the ceiling object but it's still there when I render it at the same angle...
Do you think there is any other reason for that?

Thanks! I will try to check my model thoroughly to see if there are any light leak situation
