Simply don’t use “Get Player Pawn” but rather the “Other Actor” you get from the overlap event.
Then it will who or whatever goes into the teleporter.
If you want only a character or only the player to walk though then cast “Other Actor” to “Character” / “Pawn” or to your specific player character. Or if you use the same character for bots and humans check what class the “Controller” has. Is it an “AI controller” or a “Player controller”?
