VFX Creation

Hello, I’m new to UE5 and am an aspiring animator. I just recently put together part of a 2.5 animation for my college final and wanted to practice more animating over the summer. I was trying to make an animation using effects inspired by The Spot from Spiderman: Across the Spiderverse and would like to know if anyone would be able to help me figure out how to add a looping effect to my material that I made for the character. The kind of loop I’m talking about is like the loop you see when there is a solar flare. The energy forms this strang that expands away from the main body in a kind of ring shape before dissipating and likely reabsorbing into the main body. Let me know if you have any suggestions or would like to see what I work on later on down the line.
