Sorry I’m just getting to this. Like I said, it’s been a crazy few weeks.
TurnTo should work in the network environment even if you use Camera (but I haven’t verified that). Effectively what you want is to turn towards the Camera, which modifies the Player Yaw, which gets replicated to the Server since Client movement is authoritative (to a point). I’d just try that - if it doesn’t work, you could also create a location just infront of your player, set that as the Target Location (which will get replicated up with the Ability call to the server), and you can just set your TurnTo Task Target to Location.
