UNITY 6 Logging Bugs (OVR / META XR / OPEN XR)
With UNITY 6 being released last month, we've gone in and logged some critical bugs that are preventing smooth Quest development on the new engine. If you find any bugs or, especially, find solutions let us know and leave them here!
-----------------------------------------------------------------------------------------------
BUGS:
#1: Disabled HeadTracking on play leading to stuttering and extremely low refresh rate
Notes:
- When playing preview with Questlink, it appeared that head tracking wasn't working and as a result the scene was refreshing in the headset and in the preview game view at extremely slow rates. Unplayable bug.
SOLUTION: (Credit to LuffyYu )
- Uninstall OculusXR plugin and enable MetaXR within OpenXR plugin & enable "HandPoses" within MetaXR options.
Solution notes:
- Solution seems to have fixed refreshrate on start UNLESS hand tracking is enabled -- results in same drop in refresh rate.
- Minor stuttering still present so potentially refresh rate isn't running entirely optimally.
#2 No visible controllers on preview play (i.e. controller tracking isn't functioning in this environment atm)
Notes:
- When playing preview with Questlink, there are no visible controllers with no controller inputs registering (controllers are paired with full battery).
SOLUTION:
- No solution found yet.
#3 Enabling hand tracking results in lost head tracking and extremely low frame rate (see bug #1 solution notes)
Notes:
- When playing preview with Questlink, after enabling hand tracking -- hands appear and have full tracking functionality, but we lose 360 stereoscopic view and revert to extremely low frame rates in headset and in game preview.
SOLUTION:
- No solution found yet.
#4 Non-functional builds (APKs)
Notes:
- After building an APK to correct specs and sideloading to Quest 3, the APK cannot launch and when launched by the user. we're prompted with "CANNOT OPEN" "CONTINUOUSLY STARTING". Suggesting some kind of error with the apk build/compile process (maybe some discrepancy in the DLL/SO files? -- total speculation)
SOLUTION:
- No solution found yet.
-- We've been finding some serious instability in some key parts of the dev experience with Meta XR on Unity 6 (preview, interaction SDKs, tracking, building etc.) all of which suggest a mismatch in potentially some of the lower-level infrastructure in Meta's plugins & Unity's updated engine (NOTE: we haven't observed any console logged errors during any of our testing -- on the surface things seem to be running fine, but we just have some inconsistent behaviors in engine typical of a new upgrade). We'll keep looking but if anyone finds anything let us know!

Hello, thanks for your post. I cant seems to get the XR simulator working on Unity 6. The windows launches but the camera is static and even tho I see position coordinates changing the camera / controllers are not moving at all . But the app normally works when exported to headset
Hey there Squashi11! We're just dropping in to see if we are able to provide some further insight to this Unity 6 Logging Bugs ( OVR /META XR/ OPEN XR ). We're sorry this has been an ongoing issue for you and would like to provide a channel to get this resolved. With that being said, if you haven't already, we advise you to visit the https://developer.oculus.com/support/ link. Here at the Meta Quest Support, we are not able to assist with Developer mode troubleshooting. We hope this information is useful to you. Thank you for continuously being the most important part of our VR community. Have an amazing rest of your day!
I believe I've just created a topic with a related issue which is the broken state of the Unity OculusXR Plugin in Unity 6. I have a secondary issue in that I don't see a way to submit issues from the https://developer.oculus.com/support/ link at all. I can see my old issues. I can't seem to submit new ones. For tech support it refers us here.
Basically, if you can tell me when there will be a new release of the Unity OculusXR Plugin that actually works with Unity 6, that will help with planning. What is the deal? Are you guys building this or does Unity do it?
- yeah I also have some issues in Unity 6 and I found it in new project. one of them is XR simulator. I know because it's still too new and I think it needs time for Meta SDK.in Unity 2022 LTS I also get similar issues. XR simulator doesn't run well when I try to play but I have lots of log warnings. this problem happened because I updated my game project from Unity 2020 to Unity 2022 and changed Oculus Integration to Meta SDK.more here linkuntil now I haven't found a solution. maybe you or others have an idea.
I just don't understand how you can get to version 9 of the tech stream for Unity 6 and nothing Meta related works... the plugin hasn't had an update in 6 months!!!
