How to deal damage to actors in radialforce area?

I have “explosion barrel” blueprint. After explosion I run RadialForce.

If a barrel explodes and radial force hits another barrel, I want it to explode too. The problem is I can’t register the radial force damage event on my second barel?

How to detect objects in the radial force “blast” area and follow it up with an event?

Thank you

Have you set the “can be damaged” flag on the actor?
Is the actor enabled?
