Trying to make a 2D scrolling changing background sky

I am trying to make a sky background for a flying game that will go from day to night then back to day slowly transitioning. I did some research and could not find anything that really fit this. It will be on a 2D background drop and not a skybox. Also if there are any assets that could make this easier, I would appreciate it. My art skills are not the best so it would make it easier. I wanted to make moving clouds using a particle system but it did not work well and the same for stars then use a changing color for the background. Any suggestions would be appreciated!

 

Hey, you might want to take a look at WeatherMaker, it includes a day/night cycle https://assetstore.unity.com/packag...er-system-sky-water-volumetric-clouds-a-60955
