I just looked at some code I have for the exact same thing, the only difference is I’m calling GetPlayerCharacter instead of using the level BP reference, so I’d try that first.
But… having done that, when the camera switches back, you will not be in the hallway any more, because your character is still back in the room. That’s a bit more of a problem.
Basically, once you’ve finished the level sequence, you’ll need to move the player pawn so they’re camera lines up with the matinee camera ( thinking about that )…
