Oculus Integration 31.0 Passthrough API does not work

Has anyone managed to enable the passthrough function?
https://developer.oculus.com/experimental/passthrough-api/

 

I've tried the Oculus Integration 31.0 passthrough sample scenes, but I'm getting the error "Failed to initialize Insight Passthrough. Passthrough will be unavailable." OVRManager passthrough related options are enabled. I confirm I'm using Oculus runtime v31 and OVRPlugin 1.63.0, and the experimental system property is enabled.

 

<uses-feature android:name="com.oculus.experimental.enabled" android:required="true" />
<uses-feature android:name="com.oculus.feature.PASSTHROUGH" android:required="true" />

>adb shell getprop debug.oculus.experimentalEnabled
1

 

It seems OVRP_1_63_0.ovrp_InitializeInsightPassthrough() fails.

      I've just found the Passthough API only works on IL2CPP/ARM64. It might be one of the pitfalls.

       

      I brought confusion by starting this thread, so I wrote a step-by-step guide to build the passthrough scene.

       

      - Create a new 3D template project with Unity 2021.1
      - Open Build Settings and switch to Android platform
      - Open Project Settings and switch "Color Space" to Linear
      - IMPORTANT: And change "Script Backend" to IL2CPP and enable "ARM64" Target Architectures only
      - Open Project Settings > Install XR Plugin Management and click "Install XR Plugin Management", enable "Oculus" plugin
      - Import Oculus Integration 31.0 (and click "Yes" "Restart" "Upgrade" when dialogs appear)
      - Open the "AugumentedObjects" scene in Assets/Oculus/SampleFramework/Usage/Passthrough/Scenes
      - IMPORTANT: Select OVRManager and enable "Experimental Features Enabled" and "Passthrough Capability Enabled" (I feel the line "Requires Experimental Passthrough Capability enabled in the project settings" below is a bit confusing)

       

      - IMPORTANT: And you need to enable the Quest experimental system property. This property will be reset when you reboot the Quest.
        - Open Package Manager and install "Android Logcat" from Unity Registry
        - Open "Window > Analysis > Android Logcat" (make sure Quest is connected)
        - Select "Tools > Open Terminal" from the top-right button
        - Execute "adb shell setprop debug.oculus.experimentalEnabled 1"

       

      - Back to Unity and "Build and Run"

       

      Now it should work 🙂

      >stop working for Unity builds? I
      me too.

      I'm guessing it's probably caused by the V34 update.

      I'm waiting Unity Oculus Integration update.
      I hope this cures it.

        Yes, I confirm: the same apk works well (passthrough is working) on a v33 Quest while not working on a v34 Quest... with the message :

        "Failed to initialize Insight Passthrough. Passthrough will be unavailable."

          FYI -- for anyone watching this thread, v34 is available -- and Unity "Oculus Integration" has also been updated. Woot! Build a new project and confirmed that passthrough is back baby!! 🙂  Now non-experimental...

            Just to put it out here, if your problem isn't fixed by turning on the passthrough option, it might be the post-processing. Turning off the post-processing option in your camera might help. For some reason passthrough doesn't work with it. // Pls fix this, Oculus!

              Just in case anyone is still having issues with Passthrough -- created a series of blog posts showing how to set it up 🙂 -- love any feedback

              Has anyone solved this? I am trying everything in this thread but get error "Failed to initialize Insight Passthrough"

               

              Using Unity 2019.4.31f1
              Unity OVR plugin: OVRP_1_70_0;

              Quest Runtime: 38.0.0.82.728

               

              I have tried building the example project from this git: https://github.com/dilmerv/OculusPassthroughDemos

              But it errors: "Failed to initialize Insight Passthrough"

               

              experimental features are enabled (are they even needed??):

              adb shell getprop debug.oculus.experimentalEnabled

              I'm getting that error with v50.

              Is someone using passthrough with v50 successfully?
