The exposure gets compensated when you move the camera into the dark room. Like in the real world. But it might be a bit too much compensation. I usually tweak the min/max values so the rooms are more closely lit and then increase the ‘exposure compensation’
exposure compensation: 0.5
Min Brightness: 0.25
Max Brightness: 1.0
sunlight intensity: 4.5 lux
skylight intensity 0.75 cd/m2
