Question Valve Index finger tracking in OpenXR?

I can't for the life of me figure out what I'm supposed to do here. I have a project which is using the Oculus plugin for Oculus headsets and when I switch to OpenXR I can get input from other controllers, however I would like finger tracking working for Index... how do we do this? Do we have to download some plugin like the Oculus one that we can just tick on and off and that won't screw all settings?
Or does finger tracking work within OpenXR?

It's not very clear and there seems to be no documentation on this.

 

dont' see this in spec anywhere, not looking for touch buttons, that exist already.
look for grip buttons, pinky, ring, middle

 

Is this any different now that unity has this https://docs.unity3d.com/Packages/com.unity.xr.hands@1.1/manual/index.html
Or are we still needing to look at things like
https://github.com/araghon007/openxrhands
Or this https://medium.com/@alecpizz/cross-platform-finger-tracking-in-unity-xr-5528d057ce7e
Or making our own, or bugging Valve who have no incentive in their flat corporate structure to put more work into open XR when they had already done so much for OpenVR only to have it tossed out.

 

Thats hand tracking, not finger tracking for knuckle controllers

 

One part of the three links is hand tracking and the code may still be useful for Index (knuckles) finger tracking.

 

@DevDunk @Giantbean Just tested, and to my surprise, the Unity OpenXR Hands package does deliver finger tracking data from Valve Index controller. It also seems to work with Quest 2 on PCVR, even in build.

 

Woah! That's amazing news!

 

Yes, indeed. Let's hope that this is not unwanted behavior and changed back by Meta.

 

Brief update: The Valve Index finger tracking does NOT seem to work in build, only in Editor, had not tested this before. Not sure why this is the case, did not see errors in the log.
The Quest hand tracking does work in both Editor and build, though.

 

Could you make a bug report for it?

 

Won't have time to do an example project, so could only do a plain report, which probably cannot be verified by QA But can try.

 

Ahh, too big of a project you are working in?
I sadly don't have any knuckle controllers to make a project with

 

yes, way too big, several hundreds of GB. And doing a demo project would probably take like a few hours, as the handtracking needs some extra work to be usable, the package is not very user friendly yet.

 

Another observation: Quest Handtracking only works with developer account and runtime developer features turned on

 

Could very well be, they only use it on desktop for dev. You can use in builds on all headsets probably

 

I mean in build it only works with dev account / dev features turned on.

 

Yeah, so developers can test it better

 

yes, but afair this did not work in builds before, so now it works in builds if you have dev account at Oculus
