Hey there @SPOPTHEREAL! If you’re using the Exponential Height Fog class one of the key variables you’ll need to change is fog density.
Though the basics would be to first get a reference to your Exponential Height Fog, then you can set the variables you need to change directly. For my example I use a timeline and distinct events for the Day and Night transitions, depending on how gradual you want the change, you may want to use a linear interpolation tied to your day/night time instead of a timeline like my example here uses.
