Lightning sky not loading in?

I can’t seem to get any sky to work at all on the client, I have tried several ones from the toolbox, and they work in studio before playing the game, but then just disappears in-game on the client. But still exists serverside. And changing lightning mode doesn’t work either.

that because the sky dosnt loaded yet check the output if there is any loading errors in client by pressing F9 in the game or use ContentProvider Service.
