Bug Controllers not tracking in editor with OpenXR

New thread for the issue first discussed with @the_real_apoxol in the OpenXR mega thread.

In my game Vermillion, running on Unity 2021.1.11f1, OpenXR 1.2.3, Input System 1.1.0-pre.5, some OpenXR/ hardware combinations don't have tracking controllers.

Tracking in editor and in build:

- OpenXR SteamVR with SteamVR hardware
- Native Oculus

Not tracking in editor, tracking in build:
- OpenXR SteamVR with Oculus hardware
- OpenXR Oculus
- OpenXR WMR

It is working properly in a new project with the same package settings. Vermillion started with 2019.4 with SteamVR and has been upgraded over 2020 to 2021.

These seem like interesting lines:

That's when I'm trying to get the correct ids for switching the player handedness by changing the input system usage of the controllers, it keeps trying until both controllers are tracked. It's not the cause of the issue here though, since it works fine in the build, and when using SteamVR hardware on OpenXR.

The controllers are in there, yes. Can I see anything else in the input debugger?

 

Yes, those values are actually updating.

 

You know what, it is because of my PlayerController script! But not directly - the actual cause is that XRController.leftHand.devicePosition.ReadValue() returns an empty vector in the editor when using OpenXR (except when using SteamVR hardware).

 

Sadly not, I was going to do just that but in the test project the values are filled in.

 

The position and orientation actions are only filled in with an input source on one hand when using SteamVR + Oculus, whereas both are filled in when using Oculus native. All other actions do have a binding. However, none of the actions work, including the tracking on the one hand that does have an input source.

 

Those are all zero as well. Just tested the OpenXR package controller sample scene, and there the controllers are not tracking either, but the buttons, triggers and joysticks are.

 

Adding in my project. In a new project, the tracking does work when using SteamVR + Oculus.

 

I tried it the other way around, and replaced the XR settings with those from the working project, since I saw that some of the scriptable assets in my XR settings had missing scripts. However, the issue remains. I'll see if I can reproduce the issue in a minimal copy of the project for a bug report.

 

I just face this kind of problem (OpenXR). Hp reverb headset.

List<InputDevice> inputDevices = new List<InputDevice>();
InputDevices.GetDevices(inputDevices);

I get devices if I build and run program, but if start in editor, no devices. After thinking I test this.

void Start()
{
Invoke("StartListening", 8);
...

void StartListening()
{
List<InputDevice> inputDevices = new List<InputDevice>();
InputDevices.GetDevices(inputDevices);
...

It works. Enough solution for me.

 

I remember I had a similar problem with my early project. It takes a while for Unity to recognize input/action from your HMD and it's controllers when hitting play. And the fix for me was of somewhat the same as jarmohh had. I had to listen for the controllers and when Unity found them I assigned them to their respective places, or else it would just jank out and not recognize or report any values or feedback. Kinda annoying but that was my type of fix.
