Hi guys,
I am curious if there is a way to freeze the time, let's say to sunset. I don't mean multiplayer cheating, just only for my own personal use. I like the time around sunrise or sunset. The scenery is just beautiful then.

Not currently in Mudrunner. It was possible with Spintires through Spintires+, but no one has made a mod that supports stopping the time of day in Mudrunner as yet. There is a mod like Spintires+ for Mudrunner (this is a link to a topic on the mod on this forum https://forums.focus-home.com/topic/1837/spintires-plus-for-mudrunner?page=1) which may at somepoint support time control, so worth keeping an eye on.
