disable eye adaptation (dynamic ambient light)
I attached 4 images to illustrate my point.
I have one mod installed that changes the skybox and darkens shadows FYI
Surface1 and 2 are screenshots taken on the moon at night. Surface1 has me standing with a brightly lit planet behind me, the sun however is not visible. As you can see the entire moon is illuminated. Surface2 has me standing about 10 meters to the side, where I constructed a 5*5 wall between the planet and me. Now the entire moon is dark.
Crater1 is a screenshot of me in a 20 meters deep crater on the surface of the moon at night. It's nice and dark, as you would expect. Crater2 is the EXACT SAME crater at the SAME TIME, only I dared to slightly angle the camera down towards the ground. Note the headlamp is OFF in both screenshots.
The problem here is not how dark the images are. In fact, it's the brighter one of each, which I find to be problematic.
This effect is due to the way dynamic ambient light is handled in this game. It's bad. Hencewhy I herewith inquire ye bloody fix it.
