What can change the rotation of a newly possessed pawn ?

I ran into the exact same issue. I’ve come to the conclusion that calling SetControlRotation() on the server does not replicate the change to the client. This leaves the two out-of-sync. I didn’t want to modify SetControlRotation() until I knew exactly how it was used throughout the code base, so I ended up creating my own function to force the client sync within my own PlayerController class. Here is the function definition:

	/** Force the control rotation on client and server. */
	UFUNCTION(BlueprintCallable, BlueprintAuthorityOnly, Category = "Pawn", meta = (Tooltip = "Set the control rotation."))
	virtual void ForceControlRotation(const FRotator& NewRotation);

and here is the function’s body (from my ASDPlayerController class that derives from APlayerController):

void ASDPlayerController::ForceControlRotation(const FRotator& NewRotation)
{
	if (!HasAuthority())
	{
		// Just call SetControlRotation() on the client
		SetControlRotation(NewRotation);
		return;
	}

	// On server
	SetControlRotation(NewRotation);

	// Force on client
	ClientSetRotation(NewRotation);
}

In my Blueprint I then spawn my pawn/character, have the controller call Possess() with it, and then call my ForceControlRotation() to give both the pawn and controller the same rotation on the server and client.

I hope that helps out. If someone has a better solution that doesn’t require custom code, that would be great!
