Destructible Fracture events?

Supposedly there are is an OnActorFracture event in the engine, but I can’t find it when I try to add it to a Blueprint. I did find “Assign On Actor Fracture”, but I’m unsure how to use it, if that’s even what I’m looking for. I use UE 4.6.1.

I’d really appreciate it if someone could explain how I can receive Fracture events in Blueprints. Thanks in advance!

I am also trying to find the answer to this as well

OnComponentFracture Event works
