Animate - change backgrounds

I would like to have my background image on one section change from one image to another as it scrolls down (and change back as it scrolls up). I cannot find a way to do this. Can anyone help?

Hi there…

I helped someone with a mouse hover showing an example of changing background colors. Maybe this will help you?

And this is on Hover Out:

I’d swap that out for the scroll in and scroll out triggers, instead.

Hope that helps!
