"SteamVR Not Initialized (109)" in DeoVR when enabled

[itsame-luigi]

When I have this API Layer enabled, DeoVR fails to initialize SteamVR, so the headset and controllers aren't recognized. In addition, the SteamVR dashboard icon for openxr-steamvr-passthrough isn't shown.

DeoVR logs the following:

<b>[SteamVR]</b> Not Initialized (109)
<b>[SteamVR]</b> Initialization failed. Please verify that you have SteamVR installed, your hmd is functioning, and OpenVR Loader is checked in the XR Plugin Management section of Project Settings.

openxr-steamvr-passthrough logs the following to XR_APILAYER_NOVENDOR_steamvr_passthrough.log:

("Oculus VR Plugin (Unity 2022.3.15f1 (b58023a2b463))" is what appears in SteamVR when DeoVR is launched)

• SteamVR: latest beta (build ID 15442208)
• DeoVR: latest (14.0)
• Headset: HTC Vive (original)
  • Camera: enabled at 60Hz, works as expected when RoomView is enabled in SteamVR dashboard

Thanks for the report. I can't reproduce the exact error, but I got a similar one where the controllers do not work. DeoVR seems to be loading both the OpenVR and OpenXR plugins, which I'm guessing is causing a conflict with different versions of openvr_api.dll from DeoVR and this layer. I have an update in the works that coincidentally seems to fix this issue as well.

In the mean time, you'll have to turn off the layer to be able to run DeoVR properly.

Note that DeoVR does not seem to officially support OpenXR when using SteamVR. You can force it by setting "Meta Plugin Compatibility" to On in the OpenXR tab of the SteamVR settings though. It will even enable the passthrough layer, but since it seems to run the Unity Meta plugin, it seems to only work with Metas controllers.

When "Meta Plugin Compatibility" is set to "On", DeoVR doesn't invoke SteamVR.Initialize(), so the "Not Initialized" message won't be logged because initialization is never attempted and thus the controllers are never set up.

[Rectus]

That is expected, since DeoVR runs with the Meta plugin (which uses OpenXR) instead of the SteamVR plugin. Note that this API layer will not run with the Unity SteamVR plugin, since the plugin uses OpenVR and not OpenXR.

If you want to use the features of this API layer with DeoVR properly, you would have to ask the DeoVR devs to support OpenXR with the SteamVR runtime.

I released an update which should prevent it from interfering with DeoVR when it's running in OpenVR mode, please see if it works for you. https://github.com/Rectus/openxr-steamvr-passthrough/releases/tag/v0.2.8-beta
