How do I make the sphere collision on an actor stay the same when the actor’s scale changes? Every time an event happens in my blueprint, the actor’s size increases by 20%. I want a collider around that triggers the event stay the same size. How would I do this?

Change actor’s mesh or skeletal mesh, not Capsule component.

If you change Capsule component, others(included capsule) will follow that changing.
