Inside my animation blueprint im trying to smoothly rotate the player 90 degrees, but it just teleports to the new rotation.
With the interp nodes, the current has to be a real time sample. In this case, that would be GetActorRotation. The target, as you correctly have it, is a constant.
Also, while I’m looking at it, if you’re using the default 3rd person, you might want to ‘SetControlRotation’.
