Reset Overlap

Is there any way to do overlap once again with actor that was already overlaped?
I mean… I want to to reset overlaped actors, to find actor that was already “overlaped”, when it didn’t have collision enabled.
Sorry if i’m not clear.
I have situation like this:
Actor overlaped with another actor without collision enabled. So overlaping didn’t realy happen. When I turn on collision of overlaped actor, there is no new overlap check with this actor. So I have to leave overlaped shape and enter it again to have overlap. I need to get overlap actor, that was overlaped without collision and then collision of this actor is enabled again.
I hope that I managed to explain it. Thanks for any help.

I’m working in blueprints, so I don’t know how to do it in C++, but…

You can retrieve a list of currently overlapped actors. When you are “reactivating” collision, you could do a check to see what actors are currently overlapped and do whatever to them.
