Could you provide some screenshots on what do you mean then? Don't remember the Institute's artificial day-night cycle system to be honest. There're 2 options: either "Show Sky" either "Show Sky" + LODs. The question to me is what do you want to create, so please, screens of smth similar would be welcomed. I'm attempting to create an artificial night-sky, similar to the one seen on the television show 'Ascension'. http://i.imgur.com/tCtOYRD.jpg For the most part, I got the sky to work in the creation kit (Shown below), but for some reason, in-game there's a purple sky. http://i.imgur.com/cgPlYZ9.jpg
