- where is the blueprint with the variable?
- where is the blueprint that needs to access the above?
- what is the scenario - what’s happening from the player’s perspective?
- what are those blueprints - just regular actors or something more special like the Pawn or the Game Mode
There is not enough information in your question to answer it. Best I can do is to give you a generic:
“reference the actor” or “get actor of class”
