Calamity_Jones - the attachment is not opening for me…
But as mikepurvis said - if you are spawning it and wish to reference it later, then you can keep it in a variable and simply reference it.
If it is some other unrelated actor, you need a way to identify it in order to get a reference to it.
GetAllActorsOfClass can quickly give you all the actors of a class, but you will still need to determine which one you wish to reference.
