Hair is black in shadow / Shadows are too dark

[Valentinvis]

For testing I’m using Aurora as character. I noticed that when a character moves in shadow, the hair turns to black, while the rest of the skeletal mesh colors change as they should when in shadow, and not black. What do I need to change to fix this?

Also the shadows are a bit too dark, what settings should you change to make them lighter?

This is an example with a tree that has a lot of leaves and the sun is on top, but the character is WAY too dark.

I managed to make the scene look a lot more natural, and fix that hair problem by testing different values inside DirectionalLight, PostProcessVolume and SkyLight. I may still tweak the values, but it is a lot better then before.
