What I want to do is actually this :
I have a building, I click on a button and I get a new camera that zooms on the top view of an office in the building, so I don’t want strange lightning inside the office that comes by having hidden roofs and all rest, I so disabled the exponential fog, that created fog inside the office , but I am not able to retune the light intensity seems and I get strange shadow regardless inside .
the actual light seems strange, but doesnt seem the same setting I have if I do manually , what I wanted to change is the lux intensity of the directional light inside the blueprint of the sun and sky positioning item .
edit: I used the wrong light intensity , I had to use instead the set directional light intensity .
