Is the Vive Tracker digital output pin available through blueprints?

It looks like over in Unity haptic feedback can be used to send data to the Vive tracker, accessible through the digital output pin 1. I haven’t been able to verify if this works in Unreal, or if it does which ‘hand’ in the play haptic feedback function should be selected?

Any hints on how to pull data from pin 1 through Unreal?

Ah I was really hoping unreal was caught up to where unity was.

I know the haptics work on the vive motion controllers in unreal. I’m going to try HTCs tool to change the tracker to a controller and see if it will give me anything over that pin. The HTC dev guide even mentions it as “vibrator”.

How to enable haptic on vive trackers through Steam VR with Ue4.25?
