Making a looping background

Is there even a way to do that? To make a background automatically loop, like the ones already in the art catalogue?

Maybe this will be helpful?
Technically, you can’t do that with the background alone. You’ll need an overlay.

Episode gives u some looping backgrounds but u can upload an overlay instead and make it appear like a looping BG. Check out: Looping a 3-zone Background with Speeds
