In this lesson we are going to start making loop animations and our teacher taught us the basic usage of mash. We were also asked to design our own loop animation.
I found an animation reference

I have created the corresponding model, but I am having problems with the animation.
I have animated the ball moving around the track using mash, but I don’t want it to move at a constant speed. I want it to move slower on the sides and faster in the middle. But I didn’t find a solution online.
