Hi, is this problem has solved?
I find a simliar problem: Listen Server, clients animations are jittery/laggy - #15 by Chatouille
I think the root of this issue it the ‘bOnlyAllowAutonomousTickPose’. The aotonomous character on a server(lisenten or dedicated server). Because the animation timing to be driven by client’s network updates, in TickCharacterPose on CharacterMovement.
