How to make a layer go both over and under another layer.
So I’m not a total beginner to AE, but I have something I just can’t figure out.
I have some swirling lines on a spline path I want to loop in front of and behind a character I have in my scene. I have an alpha for the character to set it apart from the background if that helps. I’ve attached pictures to show you what I mean.
But what would I do to get these behind and in front of my character at the same time? Does it involve some sort of track matte? Making the layers 3D wouldn’t work, because I need it parts of the swirls to be in front of and behind my character at the same time.
Thank you in advance.
