Okay, so noticed the sky was missing on a few other projects besides the intial one as well. But after launching session the sky is visible within the session so, I’m guessing that this is just an issue within the editor.
So, this must have been changed in the most recent update but, setting the engine scalability to Low will cause this to happen to the sky. Changing it to anything other than Low will show the default uefn sky as intended.
