    I can run a Vive through SteamVR connected to the editor with OpenXR Plugin 1.2.0 (I have to set the Runtime explicitly to SteamVR). This does not work in a build. Is the editor doing some magic with XR Loaders that I need to implement for a build? Is it currently even possible to build an app for SteamVR using Unity XR or am I wasting my time? Should I stick with Valve's Open VR plugin?

    Unity 2020.3.4f1
    OpenXR Plugin 1.2.0
    XR Plugin Management 4.0.5

    When you say you set the runtime explicitly to Steam VR do you mean in the OpenXR settings UI or on your system? The setting in the OpenXR settings just alters the runtime for when you are in the Unity Editor rather than changing the runtime on your system. I believe there is a way in the SteamVR menus to set the SteamVR OpenXR runtime as active.

    Let me know if your system runtime is set to SteamVr and are still having this issue. Thanks.

    Does this mean that SteamVR end users must configure their developer settings to play apps built with Unity OpenXR Plugin?

    The way OpenXR works on windows is there is a single runtime that is set by default. It may be SteamVR or the oculus runtime or the windows mixed reality runtime, etc. That setting is managed outside of the unity editor / player, usually by the accompanying app for the runtime such as SteamVR, oculus desktop , or windows mixed reality. Generally it should just work for most people since most people dont have multiple headsets but anyone with multiple headsets that use different runtimes may have to force the active runtime switch when switching between devices. I know the OpenXR working group has discussed making it easier on users but I dont think there are formal decisions yet.

    Have the same problem here, We use OpenXR only (without 'SteamVR for XR' plugin)
    In Editor it works fine, but after build, it just don't work, and here's the player log:

    Which headset are you using ? The original poster was using a vive but you are using the Microsoft openxr runtime so just want to make sure.

    Thanks for your replay, I have this problem for a week, just when I thought it might be something wrong with openxr, then I see your post…
    It turns out I have install [SteamVr] and [windows mixed reality runtime] at the same computer, even thought the HTV Vive device is stay plugin-in, the OpenXR still treat [windows mixed reality] as the default runtime.
    I suppose that we can have an extra option: Run base on current plugin-in device, or else more developers may complain about simular situation like this, thanks:)

    Is there any code we can manual set the runtime? I have try copy some files from OpenXRRuntimeSelector.cs but no luck:
    Code (CSharp):
    1.    
    2.     class SteamVRDetector : RuntimeDetector
    3.     {
    4.         public override string name => "SteamVR";
    5.         public override string jsonPath => @"C:\Program Files (x86)\Steam\steamapps\common\SteamVR\steamxr_win64.json";
    6.     }
    7. private static void UpdateVRReference()
    8.     {
    9. #if UNITY_STANDALONE
    10.         string envValue = Environment.GetEnvironmentVariable(k_SelectedRuntimeEnvKey);
    11.         if (envValue != steamVRDetectorInst.jsonPath)
    12.         {
    13.             steamVRDetectorInst.PrepareRuntime();
    14.             Environment.SetEnvironmentVariable(k_SelectedRuntimeEnvKey, steamVRDetectorInst.jsonPath);
    15.  
    16. #if UNITY_EDITOR
    17.             EditorTool.RepaintAllViews();
    18. #endif
    19.         }
    20.         steamVRDetectorInst.Activate();//Force Set Environment
    21. #endif
    22.     }

    [Lastest Update]:
    Problem Solve! For anyone who faces the same problem, you may try this:
    1. Open "SteamVR Setting" Panel, and show advance setting
    2. Click "Developer" Module, and set current OpenXR runtime as SteamVR

    This is a very critical problem for developers. @the_real_apoxol

    I want to publish a VR app at the viveport made with Unity 2020.3.15 + openXR. Today it was rejected. I tested it on three different Headsets (wmr, oculus, htc) and everything worked fine. In the rejection mail they said, that "there's no image in the VR Headset." They also send there player log:

    At the beginning of the player.log I see the lines:

    [XR] [17744] [17:39:44.530][Info ] ==== OpenXR Support Details ====
    [XR] [17744] [17:39:44.530][Info ] OpenXR Runtime:
    [XR] [17744] [17:39:44.530][Info ] UNKNOWN COMPANY, which is not a Unity supported partner

    We all know, that the third line should be something like:

    Valve / Microsoft / Oculus

    So it seems, that the system they use has not an OpenXR Runtime set. But because it's a market where user just download apps and want to play... it's not an option option that user should make dev settings.

    So I really ask for a dropdown like "Play Mode OpenXR Runtime" -> "Build OpenXR Runtime"

    Or maybe someone can call their friends at Steam / viveport and tell them to check and set the openXR Runtime to Steam if necessary ;)

    Unfortunately this is out of our control for now. However the new OpenXR 1.0.18 spec was just released which now has support for runtimes to publish their existence in the registry which allows for a runtime selector to be created. I dont know how or if this will be surfaced within unity yet, but it does open the door for a discussion on this topic that was not available previously. For example it would be possible to detect that there are no runtimes installed, or runtimes installed but none active. What still will not be possible however is if a runtime that does not match your headset is active. For example the Windows Mixed reality runtime is active but you are trying to use an oculus. This could perhaps be handled by a popup that detects the failure to initialize, recognizes other runtimes installed, and suggests an alternative. I will bring this topic up more with the team today.

    Thank you. I also posted this problem in the viveport forum and hope that this is solved at the one or other end.

    Still wondering, why there are so many news and support for a new technique (openXR), but at the end app don't reaches the user, because there are fundamental problems starting it.

    We are having the same problem, also posted this question in the Unity slack. For us, the only solution now seems to be to build with SteamVR instead of OpenXR I guess, as we are only targeting Viveport for this specific project.

    The active runtime is just a JSON entry in the registry that the OpenXR loader uses. You could write your own logic to check the registry and make sure steam is set and if not tell the user to set steam active (or set it active yourself if you want to change the registry).

    So this seem like a possible workaround. But I don't know, if it's a good idea if my app should change the users runtime. And if so, I could create a button, so that the user has to confirm it but still, I have no idea, how to invoke a change of a registry via c#.

    I think we are talking about this entry:

    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ActiveRuntime

    Hope someone could help with this. I found no useful infos about this.

    After several submits, which always have been rejected because on some headsets there were problems (e.g. no image in VR, controller not appearing, crash on vive pro at start, not working with ViveOpenXR,...) I'm not very exited about OpenXR anymore... this standard seem to be so complex, that it not behaves consistent.

    As @FreekM I switched to OpenVR and submited another version. Let's see... Luckily I was on 2020.3.17 that it was very easy to add the XR Plugin.

    ...and it's released! It's sad, that replacing the OpenXR plugin with openVR solved all compatibility issues. But that's it.

    Failed submits to Steam? I do not know what the state of the Vive Runtime is at this point, were you having problems with other devices failing?

    I had the same issues and in SteamVR/Advanced options one can simply click to make SteamVR the default OpenXR runtime and this solved it for me (the same exists in the Oculus app under the Beta tab). It's really up to the user what headset he wants to use and for the typical one-headset user it should not be an issue. So far OpenXR is awesome. One build. Works out of the box without any adjustments so far on Quest, Rift and Vive.

    We have a similar problem on our end. Our build was rejected because openxr crashes when the user has a wmr headset together with the steamvr runtime (steam seems to be expecting that wmr should work with steam vr as default openxr runtime). I have to say that some other games I tested are not crashing this way. The only workaround for us is using the beta of wmr for steam runtime. There seems to happen a miscommunication in the chain Unity -> OpenXR -> SteamVR -> WMR. This is not what I would expect from an universal standardization. It is a pain for developers to identify what or who is responsible for the problems here.

    I'm spending days to understand why my app runs as expected in the editor while in build my whole scene rotates with the VRcamera and no input are passing through...

    I set OpenXR as runtime default in my steamVR.
    I had to wrap all Valve code that I used in my scripts in #if !UNITY_ANDROID directives otherwise NO BUILD AT ALL!
    I THINK I did all the required settings to make it communicate with my oculus quest... but still I think wrong...

Now all is updated and I cannot get the bloody thing to open in Steam Vr at all when I press the play button to test my build. Can somebody please help me?

    Can you please elaborate on this, I'm trying to update our app from the old 2019.2 VR solution to the new OpenXR solution and it's a S***show by comparison. OpenXR just will not initialize regardless of the package manager selections or OpenXR runtimes selected.

    Do I really need to install multiple plugins for each headset? I thought OpenXR was supposed to move us away from that by making it so I just need to select the OpenXR checkbox and call it a day.

    Update - Success
    I started a 100% fresh project re-tracing all of my steps and OpenXR just worked, for both SteamVR and WMR. Comparing the packages of that project to my current project identified a few minor differences.

    Once I nuked the XRInteractionToolkit package (https://docs.unity3d.com/Packages/com.unity.xr.interaction.toolkit@1.0/manual/index.html) OpenXR started initializing XR again. As an added bonus the Convert main camera to XRRig option came back too.

    Stay away from the XRInteractionToolkit package! It's an abomination and has cost me approx. 16 hours of my life that I'll never get back troubleshooting the upgrade.

    Side Note: There appears to be an incompatibility with the new OpenXR render pipeline and graphics.Blit. If you get a stuck HMD image, or if one eye is a solid color (white for me) and the other is frozen or black. Check your post processing effects by disabling them.

    I'm having the same problem; the OpenXR build doesn't work with SteamVR. Removing the XRInteractionToolkit package didn't fix the problem. I'll post here if I find a solution.

    I like how OpenXR makes it easier working with different frameworks.
    However, one major drawback is that if I am building an app with OpenXR for steam, I usually don't care which runtime would be used (users can use any headset with steam vr), but if OpenXR didn't load up steam VR for a steam vr targeted build, there can be major issues.

    One major issues I faced:
    I noticed that pressing the system button wouldn't open the steam VR system screen and in app purchase screens won't appear for steam VR uploaded builds that uses OpenXR if the end user is using an Oculus device for example. That's not the case if the app is not using OpenXR, the user would see the in app purchase screen and it won't matter even if he uses Oculus device.

    Hi, we also have the issue that even with "Current openXR Runtime" set to Steam VR in Steam VR settings, our Unity App is not launched with the connected Vive, its only running on desktop.

    unity Version 2021.3.22

    I use
    - OpenXR package 1.10
    - Unity 2021.3.36
    - Pico4 Enterprise
    - Pico Streaming Business
    - no other SDK (no SteamVR, no oculus, no Pico, no WMR)
    - Pressing Play in Unity => Stuck in "Application.EnterPlayMode".
    Editor.log states this :

    My Steam Settings are setup to use OpenXR runtime with SteamVR.


    I also tried Khronos Simple Controller Profil :


    Same issue
