An Unreal Engine game plugin providing additional features available on Microsoft's Mixed Reality devices like the HoloLens 2 when using OpenXR.

What is the Microsoft OpenXR plugin?

The Microsoft OpenXR plugin is an Unreal Engine game plugin which provides additional features available on Microsoft's Mixed Reality devices like the HoloLens 2 when using OpenXR. OpenXR is an open royalty-free API standard from Khronos that provides engines with native access to a wide range of devices from vendors across the mixed reality spectrum. While Unreal Engine supports OpenXR natively, some additional functionality specific to Microsoft's Mixed Reality platforms is only available through this plugin.

NOTE: The Microsoft OpenXR plugin requires Unreal 4.26.0+.

Feature Summary

Unreal Engine 4.26 with OpenXR provides the following built-in functionality:

• Eye tracking
• Hand joint tracking
• Hand and controller input action mapping

The Microsoft OpenXR plugin provides the following additional functionality:

• Keyboard input routing
• Dynamic hand mesh rendering
• Spatial anchoring
• Holographic Remoting from the PC
• Photo/Video (PV) camera access
• QR code tracking
• Spatial mapping providing a mesh of the physical world
• Voice input
• Azure Spatial Anchors
• Secondary View Configuration (requires 4.26.2+)

If you're new to Mixed Reality development in Unreal, visit the Unreal development journey in the Microsoft Docs. The Unreal development journey is specifically tailored to walk new developers through the installation, core concepts, and usage of the Microsoft OpenXR plugin.

Using the Microsoft OpenXR plugin

Use the plugin from GitHub source

1. If you have the MicrosoftOpenXR plugin installed from the Unreal Engine Marketplace, first uninstall that plugin so it will not collide with the source version.

2. Copy MsftOpenXRGame/Plugins/MicrosoftOpenXR to your game's Plugins directory. Skip this step if using the example MsftOpenXRGame project.

3. This plugin maintains compatibility with older engine versions, so using the source directly may not work as expected in the latest engine release.
   If you see this message prompt, you must retarget the plugin to match your engine version:

   Modify the "EngineVersion" string in Plugins/MicrosoftOpenXR/MicrosoftOpenXR.uplugin to match the engine version you are using. For example, if you are using UE 4.27, change the line to: "EngineVersion": "4.27.0"

4. Reopen the project and the plugin will load correctly.

Install the plugin from the Unreal Marketplace

1. Install the Microsoft OpenXR plugin from the Unreal Engine Marketplace to your engine.
2. Open Unreal Engine, go to Project Settings > Plugins and search for "Microsoft OpenXR". Verify that the plugin has been enabled. You may need to restart the engine for changes to take effect.

   ⚠️ The "Microsoft Windows Mixed Reality" plugin must be disabled in your project for OpenXR to work.

Try the example project

If you want to see how each of the features available in OpenXR can be used, check out the example project (/MsftOpenXRGame) contained in this repository. This project has examples of how to use each of the features listed above, as well as a copy of the Microsoft OpenXR plugin in the MsftOpenXRGame/Plugins directory.

⚠️ This example project embeds the source code for the Microsoft OpenXR plugin which conflicts with the Microsoft OpenXR plugin installed from the Unreal Marketplace. The Microsoft OpenXR plugin from the Unreal Marketplace must be uninstalled before opening the example project. This can be done by clicking the "Installed Plugins" link below the engine in your library.

1. Clone this repository.
2. Navigate to the MsftOpenXRGame folder and double-click MsftOpenXRGame.uproject to open the project in Unreal Engine.
3. See the documention for instructions on how to stream or package and deploy to device

Some further questions when I using hololens2

I'm building an app with a ton of models , its more like a scene rather than just controlling an object. I want to bind the scene with local Spatial anchors but it seems not possible , because I have too much models and lots of them need to add interaction(can not group them all).
Because those models have real gps info,so I wander whether I could use them by send in user's real-time gps info by socket or somthing, I tried to manually update player controller's location, which works on pc but not work on headset.
Also I tried to switch the level map in order to update objects location by clicking a button. I add start ARSisson and stop ARSission in every map' bp, sometimes they don's show up normally. But if I remove stop ARSission fuction, maps show up and objects location all base on app starting place instead of now user place. I want the map and the scene controll all rebuild and update form user's real-time location by click a button. Is that possible?
Or Is there a better solution ? Pls let me know..

5.0.3 crash in FOpenXRHMD::GetDisplayTime() when starting ARSession/ Stopping Remoting/ Changing Levels

5.0.3 has a regression where a check will assert in FOpenXRHMD::GetDisplayTime()/ OpenXRHMD.cpp line 1582.
Assertion failed: PipelineState.bXrFrameStateUpdated

Workaround 1:
If building Unreal from source, this line can be commented out until a fix is made in the engine:
https://github.com/EpicGames/UnrealEngine/blob/5.0.3-release/Engine/Plugins/Runtime/OpenXR/Source/OpenXRHMD/Private/OpenXRHMD.cpp#L1582

Workaround 2:
If not building from source, the ARSession must be started and stopped in BeginPlay/ EndPlay.
Starting the ARSession must also be made after a short delay, rather than immediately in BeginPlay.

Workaround 3:
Downgrade to 5.0.2 or update to 5.1

Crashes under stress [UE5]

Hey all,
I recently made the switch to OpenXR and notice problems under high stress.
With Windows Mixed Reality I could easily display 7000+ Meshes without any big issues, now the app crashes on only seeing a fraction of the them.
Atleast this is my theorie on what is causing my crashes.
Is there some kind of performance cap in OpenXR?

Hololens 2/Unreal Engine 4.27.1 / Video Issue

I'm trying to play a .mp4 file (h.264) via a widget blueprint, which works fine in the editor/via remote streaming. Deployed to the device the widgets stay black and nothing starts playing.
I also tried activating the Hololens Media Player Plugin but then I get an Error Message that reads: "Could not create Media Playback Engine Component."
If i enable the Hololens Media Player Plugin, will unreal use this Plugin automatically or is there any other action i have to do?

Does anybody can give me an advice what to do? Any help would be greatly appreciated.

Thanks in advance!

Handtracking problems with long Sleeves [UE5]

Late Stage Reprojection over streaming?

Hi,

I noticed that Planar LSR over streaming is marked as not yet supported in OpenXR 4.26.

After doing a little more research, I see that the HL2 has Depth LSR and Planar LSR (late stage reprojection). I am assuming that Depth LSR is not available over streaming, as only video frames are being sent to the device from the streaming PC.

Is there a timeline for when Planar LSR in streaming will be supported? I seem to be noticing more jittering in holograms with the OpenXR plugin compared to the Windows Mixed Reality plugin.

Plugin version for UE5

Hello! I want to ask about your plugin update for UE5. Is that possible that it will be released soon? Or maybe you have some instructions for compile it for UE5?

Holographic Streaming unable to function after changing map

What is the secret to changing to a different unreal level with Holographic streaming?
Currently there are a few types of behaviors that occur when executing console command "open map"

To reproduce:

• download the HololensViewer template
• add a node somewhere in blueprints to execute console command "open arlevel" or use the console (~) and "open arlevel"

Behavior: The preview window will show 6-dof Head Rotation, but the image on the screen is stuck on the last frame.

===================================================
I'm trying to test the Windows Mixed Reality Plugin vs MicrosoftOpenXR Plugin

With Windows Mixed Reality Plugin my application will crash if i execute console command "open MapName" to ln 57 inside WindowsMixedRealityCustomPreset.h ( if (StereoDepthTexture != nullptr) )
How do i maintain holographic streaming on map change?
can i pass -vr -HoloLensRemoting=192.168.1.71 -RemotingBitRate=25000 somwhere in bluerpints?

Failed to load DLL: libogg_64.dll

The app packages without errors (UE5.0.3, VS2019, OpenXR-Marketplace version), but I get crashes on startup with the follow log. Maybe I do something wrong?

Yes, I suspect, that if I install VS2015 with all UWP packages, it'd solve the problem. Or not? Or there is a better way to fix it?

Unstable Holograms during remoting (VR Preview in editor) when a blueprint window is open.

Steps to reproduce.

1. Download the repo at e7a21e8 with UE4 4.27.1
2. Setup remoting (HL2 using Holographic Remoting Player v2.7.0.0)
3. Play the level in VR Preview, the holograms should be stable
4. Open any blueprint (Either tabbed with the viewport or in a separate window, it doesn't seem to make a diference.)
5. Play the level again, now the holograms are unstable and drift.

Remoting not working in Standalone or Packaged Game

Using UE 5.0.2

Remoting does not work when playing as standalone from the editor and using these parameters:

Also tested using this method:

Didn't work.

The Hololens would display "Receiving..." but never shows any image and in the logs if scene understanding is turned on, it prints this:
LogHMD: Warning: Attempting to use scene understanding in a runtime that does not support plane finding. Use spatial mapping instead.

Any ideas? Thanks!

UE5: APP quits when starting screen recording/screenshot.

Hi there

I found some problem when I'm trying to record my app from recording button in the headset menu/live-preview from PC. I figured out uap6 and XML were not the reason(which is said not supported here).
I tested different versions and found it seems to be a conflict in PV camera usage(looks like when I record the content, it automatically shuts down my XR camera in my project. Does it only allow one process running at the same time?). 

Also here are settings I used for my project:

1. the live preview from PC and headset recording works well with other apps.
2. Only "Hologram" and "Render from Camera" can be live-previewed from PC(without XR blending), app still pause and
   quits when enable PV camera sharing.
3. Camera is toggled on in AR capture, XR camera is enabled and resized 1920*1080. PV Camera texture works fine in game.
4. appx, appxbundle and certificate are fully installed.

It's really important to my project, some experience and usage need to be recorded for analysis. If there is a solution, would be perfect. Thank you so much!

Deploying UE HoloLens projects leaves temporary files that cannot be deleted

I am unsure whether this issue is related to UE or to the toolkit for UE or to Windows Holographic itself, so I will open an issue for UE on this as well: The problem is basically described at https://docs.microsoft.com/en-us/answers/questions/732279/unable-to-delete-hololens-2-temporary-files-after.html and summarised as

Deploying UE OpenXR projects from the UE editor using the device manager causes either the toolkit or the engine or Windows itself to produce temprary files on the HoloLens, which are never deleted. Moreover, the files are somehow locked (even after a reboot) wherefore they cannot be deleted by the disk cleanup in the settings app (reports that some files remain). After deploying an app sufficiently often for debugging, the disk is full and the only solution is to factory reset the HoloLens.

UMicrosoftOpenXRFunctionLibrary::GetPVCameraToWorldTransform always returns identity

I try to port an ArUco detector from plain D3D/C++ to Unreal. In order to transform the camera-space coordinates to world space, I call UMicrosoftOpenXRFunctionLibrary::GetPVCameraToWorldTransform. My understanding is that I can call this method at any time while the game is running. However, regardless of whether I call it from a Blueprint or from C++, the result is always an identity transform, i.e. it seems the camera is not tracked.

As I assume the platform is PLATFORM_HOLOLENS when building for HoloLens in UE, I would expect that

FTransform UMicrosoftOpenXRFunctionLibrary::GetPVCameraToWorldTransform()
{
#if PLATFORM_WINDOWS || PLATFORM_HOLOLENS
	return MicrosoftOpenXR::g_MicrosoftOpenXRModule->LocatableCamPlugin.GetCameraTransform();
#else
	return FTransform::Identity;
#endif
}

calls the plugin, which returns the cached PVCameraToWorldMatrix, which is updated in UpdateDeviceLocations:

		PVCameraToWorldMatrix = FTransform::Identity;

		if (Space != XR_NULL_HANDLE)
		{
			XrSpaceLocation SpaceLocation{ XR_TYPE_SPACE_LOCATION };
			XR_ENSURE_MSFT(xrLocateSpace(Space, TrackingSpace, DisplayTime, &SpaceLocation));
			const XrSpaceLocationFlags ValidFlags = XR_SPACE_LOCATION_ORIENTATION_VALID_BIT | XR_SPACE_LOCATION_POSITION_VALID_BIT;
			if ((SpaceLocation.locationFlags & ValidFlags) == ValidFlags)
			{
				PVCameraToWorldMatrix = ToFTransform(SpaceLocation.pose, XRTrackingSystem->GetWorldToMetersScale()) * XRTrackingSystem->GetTrackingToWorldTransform();
			}
		}

As I did not manage to start any UE HoloLens project from Visual Studio, I am unable to tell whether the problem is that Space is invalid or that the location flags are not as expected.

Is there anything special that needs to be turned on for this to work?

HTTP Request Failure

Hello,

We are trying to download a file from our server (Binary) on HoloLens Native Builds):

1. HEAD request does not trigger a Response (Works for Windows, Android and IOS, so assuming not an issue with server)
2. GET request fails in CreateRequest (in HttpIXML), (called from UE4 ProcessRequest)
   The GET Request Works for JSon Objects (we are not providing any content-type in header info for GET)

Using Unreal 4.27.2 Built from Source.

Any suggestions to resolve this?

Best Regards

GetPVCameraToWorldTransform always returns identity since V1.1.10

Hello,
I am launching the application MsftOpenXRGame V1.1.14 on my HoloLens 2 with UnrealEngine 4.27.2 and GetPVCameraToWorldTransform always returns identity.
I tried many versions of the plugin (V1.1.8 to V1.1.14). Only 2 allow me to get a valid transform, V1.1.8 and V1.1.9.
For the versions greater than 1.1.9, I was able to debug them by attaching visual studio to the HoloLens application, and I realized that SpaceLocation.locationFlags is always equal to 0.

if (Space != XR_NULL_HANDLE)
{
	XrSpaceLocation SpaceLocation{ XR_TYPE_SPACE_LOCATION };
	XR_ENSURE_MSFT(xrLocateSpace(Space, TrackingSpace, DisplayTime, &SpaceLocation));
	const XrSpaceLocationFlags ValidFlags = XR_SPACE_LOCATION_ORIENTATION_VALID_BIT | XR_SPACE_LOCATION_POSITION_VALID_BIT;
	if ((SpaceLocation.locationFlags & ValidFlags) == ValidFlags)
	{
		PVCameraToWorldMatrix = ToFTransform(SpaceLocation.pose, XRTrackingSystem->GetWorldToMetersScale()) * XRTrackingSystem->GetTrackingToWorldTransform();
	}
}

Do you have any ideas on how it can be resolved ? Thanks.

Get microphone input when Holographic Remoting Overview

Hello，
When writing holographic remote applications using Unreal Engine. We can now use the voice input function of the Hololens 2. We can also stream sound from the PC to the device. But we can't get the microphone signal directly like a Bluetooth headset. We want to be able to recognize some voice messages through AI. This means that sometimes the voice message does not match the pre-programmed voice input.So, can we stream the microphone signal to the PC during holographic remote playback? Or, can the Hololens2 be connected to a PC as a Bluetooth audio input?

This option is needed because UE needs collision in order to generate navmesh data.
Is it possible to fix this? Thanks!

OpenXR initialization errors

I'm trying to switch from WMR plugin to Microsoft OpenXR. Tried this version and UE Marketplace version in both 4.26.2 and 4.27.1. Always get the same warnings and, of course, features don't work. In particular, FHolographicRemotingPlugin isn't loaded and I can't use Remoting Connect.

Do I miss something in setup? I disabled all other VR and AR plugins in UE4 except Hololens, bult-in OpenXR's and Microsoft OpenXR.

But when I try to compile for win64, the following errors are raised :

I didn't find anything about those errors... So two questions :

• Is it possible to build Microsoft OpenXR for win64 ?
• If the answer is yes, have you some clues to fix this ?

Thanks !

Remoting issue (I think)

When I am remoting I get this error from time to time, it doesn't crash the editor, but it makes debugging code a pain because it keeps hitting a breakpoint.

LogOutputDevice: Error: Ensure condition failed: CurrentGCObject->GetReferencerName() != FGCObject::UnknownGCObjectName [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Misc\GCObjectReferencer.cpp] [Line: 166] 
Please make sure all FGCObject derived classes have a unique name by overriding FGCObject::GetReferencerName() function. FGCObject::GetReferencerName() will become pure virtual in the next engine release. See callstack for details.

Thanks!

Unable to build for HL2 with blueprint Nativization enabled

Steps to reproduce:

1. Download the repo at e7a21e8 and open it with UE4 4.27.1
2. Set the Blueprint Nativization Method in Packaging settings to "Inclusive"
   
3. Build the project and get these errors
   

MicrosoftOpenXR/Public/MicrosoftOpenXR.h(105): error C2039: 'IUnknown': is not a member of '`global namespace''
MicrosoftOpenXR/Public/MicrosoftOpenXR.h(105): error C2061: syntax error: identifier 'IUnknown'

Blueprint Nativization drastically improves performance for Blueprint projects, so it would be really great if this can be fixed.

ACTION REQUIRED: Microsoft needs this private repository to complete compliance info

There are open compliance tasks that need to be reviewed for your MixedReality-Unreal-PlatformExtensions repo.

Action required: 4 compliance tasks

To bring this repository to the standard required for 2021, we require administrators of this and all Microsoft GitHub repositories to complete a small set of tasks within the next 60 days. This is critical work to ensure the compliance and security of your microsoft GitHub organization.

Please take a few minutes to complete the tasks at: https://repos.opensource.microsoft.com/orgs/microsoft/repos/MixedReality-Unreal-PlatformExtensions/compliance

• The GitHub AE (GitHub inside Microsoft) migration survey has not been completed for this private repository
• No Service Tree mapping has been set for this repo. If this team does not use Service Tree, they can also opt-out of providing Service Tree data in the Compliance tab.
• No repository maintainers are set. The Open Source Maintainers are the decision-makers and actionable owners of the repository, irrespective of administrator permission grants on GitHub.
• Classification of the repository as production/non-production is missing in the Compliance tab.

You can close this work item once you have completed the compliance tasks, or it will automatically close within a day of taking action.

If you no longer need this repository, it might be quickest to delete the repo, too.

Are there any plans to implement the HoloLens 2's Scene Understanding in UE4?
Or is there a way to do this in the engine already?

Thanks.

Dictation voice input

Hey! I'm trying to using this plugin to add voice input as dictation into game. I don't understand, how to send recognized phrase into my character. Can you help me?

Microsoft Holographic AppRemoting Runtime runtime version 2.8.1

I'm trying to switch a UE 5.0.3 Project over from using Windows Mixed Reality to the MicrosoftOpenXR Plugin and use holographic remoting. Currently, I'm able to use holographic remoting in the editor to test my project but when i package for windows development and run the application will crash.

arnocMain.exe SampleLevel -game "-HoloLensRemoting=192.168.1.71" -log
