If anyone can definitely pitch more than 180 with “Add controller pitch input” on the Thirdperson template it would be very interesting as to exactly how. That function has strong multiplayer code - unlike Flyingpawn.
Based on this thread I tried this custom player controller on the Thirdperson template but still only pitches 180 for me. You also need to set these on the (empty graph) test character: “default land mode” to “flying”, “gravity scale” to “0” and “rotation rate” boxes to 100/100/100.
