I have recently retested the mod, and it appears to be working correctly.
I'm not sure what you mean by the skybox is turning red, could you elaborate on your statement?

You can try reinstalling the workshop mod to see if that should resolve your issue.
Or you could check for any other mods that are conflicting with this mod.

This workshop mod doesn't plan on getting an update anytime soon, cheers.

this mod is broken if your wondering why your skybox is turning red it is this mod
