Attaching object to only one sphere

I want to attach a circle inside another circle. Right now there are 4 moving circles, but I only want it to occur on of the 4 moving circles.

Hey there Booitsbill,

Can you show a photo to demonstrate what it is exactly you’re looking to do? Sounds like you may want to parent one of your circles to the other in the blueprint editor.

Hello SE_JonF

I have 4 moving gray circles. I want to create a red dot that appears randomly on one of the 4 circles. Thanks!
