VR in not working in build

Hey All,
Using Unity 2019.3.3f1 and an Oculus Quest in link mode VR no longer works in a build (editor is fine). I spent the morning updating various packages (XR Management 3.0.6 -> 3.2.6, Oculus XR Plugin 1.1.5 -> 1.3.3) and now when I start the built game I stay in Oculus Home. Reverting to the previous package versions also does not work. Has anyone experienced this?
Cheers,
Colton

 

You shouldn't be updating any packages except via the XR management package, which will do it for you. If you do it externally to that, there is no guarantee anything is going to play nice.

That said, try a full quest restart/reboot. Sometimes also, the permission for Quest to use untrusted sources or external stuff needs to be applied again. These niggles are common with Quest-over-link dev.

 

XR Management 3.2 was specifically launched (see the stickied thread) as not supported in 2019.3.

(I have voiced my opinions in that thread already, TL;DR: "this is a bad idea").

I would immeidately delete / downgrade XR Management if I were you - even the team that makes it doesn't believe it works in 2019.3

 

Hey @mfuad, I believe you are correct (these are unrelated) as everything works fine in a new project with the same settings and package versions. I am attempting to fix some errors that occur when my project starts (even in a blank scene). The specific error I am currently trying to fix is a serialization issue:

A scripted object (probably UnityEditor.XR.Management.XRGeneralSettingsPerBuildTarget?) has a different serialization layout when loading. (Read 52 bytes but expected 108 bytes)
Did you #ifdef UNITY_EDITOR a section of your serialized properties in any of your scripts?
(Filename: C:\buildslave\unity\build\Runtime/Serialize/SerializedFile.cpp Line: 2269)

Could this actually be an issue with the UnityEditor.XR.Management.XRGeneralSettingsPerBuildTarget?

Cheers,
Colton

 

Removing all XR packages and re-adding them seemed to fix the issue.
