Hello, I have shadow issues in my project as you may see in the screenshot. The surfaces of meshes that facing the sky is lit like I desire. But the other sides that facing the landscape are unnaturally dark. I turned off “lower hemisphere is solid color” setting but that helped me very little. Also tried to play with directional light, skylight and sky atmosphere but couldn’t solve my problem. Any help would be greatly appreciated.
Is this a single mesh?
the upper part is the same mesh as the floor.
If lumen is used the best thing to do is turn auto exposure off, or set the min/max to 1 in your post process volume, project settings> extend luminance range, as well.

It is not a single mesh. The tower made from the planks can seen in the screenshot. And the roof is also made from single planks. All of them are seperate. (The meshes are from megascans)
Auto exposure is already turned off, and the “extend luminance range” did not help me or I couldn’t use it properly in post procces settings 
The tower roof look like this with rect light:
Beneath of the tower look pitch black as well, no matter what the skylight and directional light intensity is:
Note: Changing graphic settings doesn’t help as well.
default lumenence range is in project settings, recommended for lumen. if your light source is under it that makes sense, but a directional atmo light, looks like you would need 1. something for the indirect to bounce off of moreso than just the floor, given its darkntess and the cloudcover.
I dont think the lower hemisphere injects light using lumen.
that last photo, everthing is darker colored, albeido helps determine the indirect lighting, you can try to increase the indirect lighting intensity. to see is you can get the result you are looking for

Already turned on the luminance range but I can’t see changes. I don’t know where to find directional atmo light though.
If I crank up the Indirect lighting intensity in directional light like 300, light bounces like I desire. But this time some other scenes look strange. But I believe I am making progress thanks to your informative answers.
I have one last question: Do you know why “shadow amount” setting in directional light doesn’t affect any shadows in my project. I am changing the value from 1 to 0, nothing is changing. Also in skylight, indirect light intensity doesn’t seem to be working.
Im sorry I mean a directional light with atmospheric light enabled. Typically I add, a directional light, sky atmosphere, exponential height fog and skylight, check atmospheric light in the directional light details. Make skylihght and direct movable.
One of the best explanations ive found
