After a week and a half of trying I still can't get the trackers working with Unity - for the sake of testing I've made a simple project where the intention is to translate the tracker data onto a simple cube.

The documentation for deployment of these isn't great - is it possible to deploy using a similar method to the controllers and HMD (Tracked Pose Driver?)

Hi @RMFoley92,
Please help to confirm below info for us:
1. What platform are you using? Android or Windows?
2. What device and the device version are you using?
3. Is there any error code or specific problem that you encounter

Thanks.

Hi,

1. I'm building to XR Elite using Android utilising OpenXR

2. Headset Firmware is currently 1.0.999.508 - Trackers are currently trying to update to 1.0.999.120 however the poor internet performance of the headset means they're unable to do so. They just get to 97% and fail the Firmware update. The headset is picking up the trackers when setting up and this process works fine, however I'm unable to then apply this to a Gameobject in Unity

3. I don't get any error codes when trying to implement the trackers, I've currently been trying to get the trackers working using the Tracked Pose Driver, the same as the traditional Trackers can be deployed as well as the HMD and controllers. I've tried to follow the deployment guide you've posted above but can't figure out how this translates into actual deployment in Unity.

Hi @Vivi Wu  ,
With the beta feature for the VIVE ultimate tracker, can I use the trackers directly with the PC without any headset (maybe using null HMD driver as in SteamVR or something similar). I just want the to access the tracker info within unity and use it to control a gameobject. Will I be able to do this with the beta and no headset?

Is there really no way to use this without a headset?

I'm trying to use the Vive Ultimate Tracker has a general purpose 3D tracker as a Windows application.

If not I'm going to have to return it.

Managed to get the trackers somewhat working in PC VR.

I've joined the discord (https://discord.gg/viverse) to get access to the beta.

I installed the Vive Streaming Hub (https://www.vive.com/us/support/vs/category_howto/using-vive-streaming.html).

Paired & calibrated the tracker with the help of an Oculus Quest 2. Assigned the tracker as Camera in SteamVR.

I logged in & followed the VIVE_Ultimate_Tracker_PC_OpenXR_v2.pdf, however, it is not working. I'm on Unity 2022.3.16, URP, OpenXR Plugin + Vive OpenXR.

Added the HTC VIVE Tracker Profile C# script to the project:

Created an Input Action asset and assigned the camera tracker:

I get a warning: 

No GetDeviceLayoutName() override detected in HTC Vive Tracker Profile. Binding path validator for this interaction profile is not as effective. To fix, add GetDeviceLayoutName and GetInteractionProfileType override in this profile.

I was able to get the tracker working in Unity with the SteamVR plugin, but I'd vastly prefer using OpenXR.

(If my previous post with error messages goes through) I was able to fix it, I changed: 

HTCViveTrackerProfile.cs
// line ~14
// Comment out:
//using PoseControl = UnityEngine.XR.OpenXR.Input.PoseControl;
// Change to:
using PoseControl = UnityEngine.InputSystem.XR.PoseControl;

Unity deprecated UnityEngine.XR.OpenXR.Input.PoseControl (it says so if you mouse over it in Visual Studio), they suggest UnityEngine.InputSystem.XR.PoseControl instead.

Now I just need to keep something on my Oculus Quest 2's sensor to make it think a user is in the headset, and I receive tracking in Unity. Trying to figure out if I can eliminated the headset now.
