I like this tutorial very much and had the same issue with replication. This is what I’ve changed so far in my ThirdPersonCharacter blueprint to get this work in multiplayer. I’m setting IsCombat (which is now RepNotify) via custom event (only) on server and ‘Orient Rotation to Movement’ (only on server) as well and afterwards fire a further custom event as multicast for all which is finally executing that interface function for the anim blueprint. You could ignore/remove that EventOnMovementmodechange and IsFalling stuff on the screenshot - it’s basically a first try to get rid of that combat mode if the character is falling from an edge but I’m not sure if I leave it that way or mix the falling animation with the combat animation via layered blend per bone in the anim blueprint instead afterwards. I’m even not sure if there is a simpler way to spread that “OrientRotationtoMovement” for all (I tried with a multicast at first but it did not work like expected so I leave it that way currently).
