 So lighting is cool but you want to know how to make a night sky, not a problem. Now this is a bit of an older solution but it's also extremely simple. On the right under settings, check show engine content, click the engine folder and then in the search bar type sky and drag it into your scene like so. Now this new sky box should replace the old sky box and then once you've dragged it in, you might have to go to your sky atmosphere and reduce the ray lay in order to actually see the stars. And if you go down under detail, the most important thing here is the sun height. You can drag it back and forth from day to night and the night comes with these awesome beautiful stars. But before we get there in the daytime, the sun's brightness can be controlled here. Cloud speed which really should have been called cloud rotation can be controlled here and how clear the clouds are are determined here. Now here we can control how clear the stars are and that's really it. There are some other cool color settings that you can mess with but as far as just getting a quick, easy, beautiful night sky onto your scene, just replace the sky box with the legacy one. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
