“As you can see in this screenshot, sunlight transitions to shadow between buildings as the light bounces off the buildings surface next to it. This is global illumination which makes light realistically reflect off surfaces.
The effect will be most noticeable indoors with sunlight shining through windows, the sunlight will bounce around the room creating realistic lighting conditions.
This will also make nights a lot more realistic with light sources illuminating objects around them, this includes moonlight which will be far more realistic.” ~ Rinocore.
