What do you mean? Like it’s the night suddenly? The lighting or darkness are not changing in the game, there’s no weather or night cycles, so I don’t get it.
Hmmm, weird…I have these shots I took when it was dark. No idea what I did but seems like a bug then, or maybe some timer issue with any weather asset you may be using? Maybe the game needs to run a while for it to happen, but on the second playthrough I was loading from a save game, so I don’t know.
