Unity 6000 - Head tracking issue

[zursona]

Hello,

After newest version of Unity 6000, i have issue with head tracking.

Every time i create new project, import Meta XR All-in-One SDK(Currently 65.0 v, same with 64.0), everything works fine, except head tracking. when i do exactly the same with unity older version (for example 2022.3.15f1) tracking works.

there are few things i can mention. during launch, frame rate is like 72 FPS, when normally its 600+
gives two errors and a warning. all i do is install unity editor(right now its 6000.0.2f1), create empty project(Clean project without anything), import SDK and launch.

Your project uses a scriptable render pipeline. You can use Camera.stereoTargetEye only with the built-in renderer.

Did the issue that the entire scene will be moving when moving the headset happen on your side?

[zursona]

Yes

[LuffyYu]

Have you fixed it? If so, could you share the solution? I am stuck here.  Thanks.

[zursona]

No, i'm stuck too

[LuffyYu]

I'm diving into it. Now I have fixed tracking HMD.

Add Tracked Pose Driver to CenterEyeAnchor

 The controllers tracking is still not working.

[LuffyYu]

I made it! I will share it later.

For those who experience the same problem, I posted my solution here.

thank you for your answer! it's just looks like workaround rather then solution to me. I'v managed to fix head tracking with your suggestion, now i lack hand and controller tracking. i want to use oculus plugin and as far as i know, they cannot co-exist, so searching forward 🙂
