Motion controller inputs get routed to non-vr player when 'Skip Assigning Gamepad to Player 1' is enabled.
Combined VR + FPS template example project attached.
Result: Keyboard, Gamepad, Motion controllers all control VR Character.
4. Enable 'Skip Assigning Gamepad to Player 1' in project settings
Result: Mouse and Keyboard control VR Character. Gamepad and Motion Controller control Non-VR Character.
Expected: Motion Controller inputs are routed to VR character
