When Emissive map dissabled, the object is still lighting. How to quickly update view for single object? (in large scene)

I have a city with lots of buildings. When I turn off the window lights of one single building (unchecking the emissive map and save), then the building is still lighting.
I guess this has to do with “building light”.
Building lighting stays a long time at 0% and takes overall 15 minutes (rtx 3090 and fast AMD threadripper)

  1. How to update the view (even roughly would be okay) of the building with lights turned off?
    It is displayed correctly and instantly in the editor, but not in the scene view.

  2. Even after updating ALL lighting (which took 15 minutes) the building is still lighting with it’s emissive map, which is actually and definitely turned off.


Many thanks for help
