SteamVR Controller Binding

Hey,

I’m having a really hard time getting the buttons/pads on the SteamVR controllers to work with Unreal. The triggers seem to work fine, and Unreal responds to touching the trackpads.

However that response is entirely binary - its either on or off.

How can I get/create input events for the other buttons/axes on the controller? Unfortunately all the Google results I’ve found all refer to old pre-4.8 issues involving multiple controllers not tracking correctly.
