Adaptive Dome Light: Square Artifacts

[kosso_olli]

Hey, I know there were some issues with artifacts when adaptive dome light was used.
Most of the times this was caused by non-physical settings such as cast shadows off or objects not being visible to camera.
Yet, I have a scene here which uses none of these unphysical features, and I still get the typical square artifacts. Is there any other option I can try, besides turning off adaptive dome light?

EDIT: It seems the problem is caused by another plane light sitting directy on front of the windscreen. If I turn this off, everything is fine. It looks like that light is blocking the domelight in some way. Is this a known problem?

Hey, did anyone check if this is a bug?

I had a similar problem and send a scene to support. Problem is logged and they are working on it. Maybe it will solve yours too.

It has to be the plane light in front of the windows. This somehow messes up the adaptive dome light.

It's a known one (as Manuel said). It will be fixed.

+1 would love more stable adaptive dome light
