Day/Night Cycle Light Passes Through Ground

I’ve posted this to the Unreal Forums, but I’m on a deadline and I’d like to get this fixed ASAP, I’m also unsure if my updates are failing to post on the Forum, or if its just slow with pictures.

Basically after following the Day/Night cycle tutorial by Tesla Dev I’m having an issue where the Sun, being below the map at night, has its light affecting the map itself. It’s as if the sun is passing through the ground and illuminating the level. I was informed on the Forum that I need to set the suns intensity to 0 in the Blueprint, but I have no idea how to go about this, as this is the first Blueprint I’ve ever created. Could anyone advise me on what to do? Even if its just annotating the screenshot?
