Change SkySphere from BP

I know this is a very vague question, but I have no idea where to start. Here’s what I want to be able to do:

Control my sky sphere from my Character BP.

How would I do this? Should I cast to the skysphere? If so, how?

Thanks!

Use GetAllActorsOfClass node. Choose the ActorClass input. Since there is only one Skysphere in level BP, get the first element of OutActors array.
