Day/Night Cycle not working.

I watched a tutorial: on how to make a day/night cycle, but for some reason after I connect “AddActorLocalRotation” to “Update Sun Direction” instead of the sun rotating the skybox turns Reddish and the sun disappears. I followed all the steps in the video, and rewatched the video, but couldnt find what I’m doing wrong. Everything is the same. Has the bluepring been changed somehow?
