Is this the most effective way to make a decal follow my character

Hey guys! I am newer to UE4 and I have been playing around in blueprints. I wanted to make an effect where a circle follows a character around when they press a button. Currently I have it set to spawn a decal with a lifespan of 0.001 in a loop. When they move it moves along with it but I don’t know if this could be resource intensive or if there is a better way to do it.

I would appreciate any help.

Hey! Maybe you could attach it to a spring arm and play with toggle visibility?
