Open VR Pawn, event graph
Create InputAxis MovementAxisLeft_X, and right
(Based on input from project setting)
For Smooth rotation:
Create nodes on axis right, with added SmoothRotationSpeed variable, set speed as 5
For Snap Rotation:
Use Left axis X node, add SnapRotationAngle vairable, set value as 45
For inverse direction, add <= (less equal) node instead of >=:
(-1 in multiply node is to set inverse direction of rotation angle)
