Oculus VR Unity 6000.0 No Tracking

Unity Engine

I have an application that was working for Rift AND Quest (and some other platforms) in Editor and Build under 2023.2.

I did a standard upgrade to 6000.0.1f1 and - although everything else is working - for Rift and Quest the application no longer does any head tracking or controller tracking.

I have tried looking at every configuration I can think of. The OVRManager and OVRCameraRig scripts on the camera rig are all reset to defaults.

Meta XR Core SDk is 64.0.0

Oculus XR Plugin is 4.2.0

Does anyone have any idea what is going on ? Please ?

For anyone searching - I don’t know what caused it. I just unloaded everything and reloaded everything a few times and eventually something obvious changed the faulty internal config and it just started working.

Sometimes the Meta SDK is too “idiot proof” for its own good

Can you elaborate on “unloaded everything and reloaded everything”. I am facing the same issue for the past two days.

One weird problem arose when I tried Unity 6000 and Meta XR Interaction.

The entire scene is moving when moving the headset when I ran the example scene.

I have tried SRP and built-in render pipelines, but it didn’t help.

Any ideas on this problem?

Unity: 6000.0.3f1
Meta XR SDK: 65.0.0
Oculus XR Plugin: 4.2.0

It’s not the entire scene is moving, it’s the headset being not tracked thus the camera isn’t updating its position/rotation.

I scraped out Meta XR tools and using OpenXR instead.

I see. Thanks for your explanation!

Before upgrading to Unity 6000, my project is based on Meta interaction SDK.

I have no choice but to upgrade to Unity 6000 as one new feature is only available in Unity 6000.

BTW, XRI also doesn’t have this problem.

I will dive a bit to see if I can fix it without giving up my previous implementation.

FYI, I just fixed hmd tracking by only adding Tracked Pose Driver to CenterEyeAnchor.

I just figured it out! I will make a new post later.

Hey guys, this fixed it for me:

Not that you will find two dll meta’s in your root folder, the one you wanna change is in the Win64OpenXR folder. Change it while the app is running, hit save, quit editor, restart editor and go into quest link and you will see both head and hand tracking works as intended.
