[Multiplayer BP] Viewport/Mouse Position Per Player Controller?

I’m not sure if this video helps diagnose the problem or not, but I’ve moved to Casting to the Player Controller and getting the Rotation variable that I want to use to set the Relative Rotation of the Player Character’s Mesh. The same issue occurs that I mention in my Edit above.

I’ve tried to break down what you said in your original post but I get caught up around the tricky part.

Also, what does Calling mean? Is that the same as Casting?

Thank you,
