imo it is unrealisticly dark, all I can do at night is ruining with grid shown (F3) park my char at some point where I can afk grind.
My suggestion is to reduce the darkness overall or reduce the amount of night time that is way too dark, 0- 3 am darkest or something like that. Realistically it must depend on weather and how much stars are visible, moon phase, amount of clouds etc
As a cg artist worked on AAA game and movie titles I can say that the game at night looks broken.
As a gamer - here is what happens - I came home from work and want to play for 2h, I log in and it's a night... fk it I'll play something else today
