I have been working on a project recently that will require an animation sequence. I have gotten the hang of every technique in Synfig to make my idea a reality, except for one.

I am looking to merge the two circles together so that the circumferences of each overlap each other. How could I go about making this happen?

Hi!
Something like this maybe? When you move the purple circle over the blue one then the overlapping part changes color, creating the fishbladder.

That’s exactly what I was looking to do. I did some research on the Spline tool and how to make Outlines, but I can’t seem to work it out. How exactly did you get the circle outline for both circles the way you did?
