No I’m not using the GearVR. Oculus DK2.
I’m using mouse center interactable on mine, which I imagine wouldn’t work on GearVR.
I investigated the line trace technique but decided against it because from what I saw I would have to set up hit boxes for every button. I decided that mouse center was a more versatile hack, and that with the possibility of the interaction method having an official fix soon that fewer moving parts would make the transition easier.
