Skybox disappears when in play mode

Hi!
I’m new to unreal engine, so this is probably nothing special, but anyway I couldn’t google this out.
The problem is that I’ve made something to the skybox and now it’s present in edit mode but quickly disappears when I hit play and the sky gets completely black.
What might be the reason for this?

Thanks

Hi!

Check attribute “Actor Hidden in the game.” It is mean that objects will hidden during game play.

Thanks for your reply, but it’s not the reason. The option is definitely unselected, and it was the first thing I checked out.
Here are 3 screenshots of what happens when I hit play in the editor. It’s not a big deal here as it’s just a tutorial propject, but I’d like to know what to do if this happens in a real project.

Well, I’ve just copied the entire sky box from a blank project, and it’s fine now. I’m sure I’ll find what was the reason for this later

@caseyryan did you ever figure out what the problem was?

Make sure “Initial Life Span” is set to 0. 0 = Forever

Under Detail panel, in the Actor setion.

I believe your SkySphere probably didn’t have a Directional Light Actor chosen – this causes the SkySphere to hide on play.

I just had this happen to me as well. In my case, the “Simulate Physics” checkbox was accidentally checked under Physics. This caused the Skybox to drop since Enable Gravity was also checked.

This answered my question. I created the Sky Sphere from scratch and so “enable gravity” was on. So when pressing play, the sky sphere fell, and I no longer had clouds. Disabled gravity and I have clouds!
