It's great that you're improving the game but how can you be adding day/night cycle without serious testing..
This is how the game looks for me during the night (''Beautiful' quality settings)
I am standing on a side of a hill if you are wondering...
The game is unplayable.
As discussed with JSL, a gamma setting is under investigation. Still, it should be good out-of-the-box so a couple of questions out of curiosity:
- Does the output_log.txt contain any errors?
- Do you have some more images of the valley with trees and such?
- Does it happen with specific advanced graphics (post-fx) settings?
