Hi, sure!
Do you use a day night system?
Or do you tint the maps by yourself? ( in this case just set the parameter "use map tint" to true and it should work.
If you use a day night system then you should have a "switch" that turns on when it is night time.
just set the night switch Id from the parameters drop down menu to your night switch id.
Or you can just set this parameter (use map tint) to on/true it will then ignore the night switch and just use the current map tint the player comes from:
i hope that helps! :)
