    Valve Index thumbsticks only return 0

    Is there a trick to getting the Valve Index thumb sticks to work in UE4?
    I have a VR project that works great on a Oculus CV1 and Quest with a link cable, but my Valve Index thumbsticks always return 0 so I have no movement in my game.

    I first noticed this in UE4.24 and reported it as a bug, but I didn't hear anything back and so I've been using my Oculus CV1 for development. I just updated to UE 4.25 and found the same issue still exists.

    Is this a bug or am I missing some extra set up that the Index needs? All the other buttons seem to work, it's just the thumb sticks I can't get a value from. If it makes a difference I'm using C++ and not BP.

    I encountered something similar - cant say for sure but after adding some additional inputs it seemed to work.

    If adding those inputs work for you be sure to post back....

      Thanks for the reply, but unfortunately that didn't work for me.

      I just tried adding all the controllers as well as deleting everything and starting again, but still the same.
      I did just notice if you open the Index menu while testing the game and select show bindings, all my buttons show up as bound to the key names in UE, but my thumb sticks are shown as not bound to anything.
