I know what sky colors I want, but when I add the day and night cycle I created into my level it goes to the default sky colors and I’m not sure how to change the colors of the whole cycle (night, sunset/sunrise, day). I thought I had to do it in the C_Sky_Horizon_Color, but it didn’t seem to make any changes to the sky. Any help would be greatly appreciated!

You have to edit the C_Sky_Zenith_Color color from the blueprint for the BP Sky Sphere. You can edit the blueprint directly or find the file here: Engine\Content\EngineSky\C_Sky_Zenith_Color.uasset
You have to refresh the material to see the updates, and I’d suggest tweaking the horizon one as well since it blends between those 2, Zenith being directly up.
I’ll give that a shot and see if it works. Thanks for the reply!
Just tested this out and it worked. Thanks for the help! Appreciate it
