I am using the Focus 3 and Vive Business Steaming (VBS) to wirelessly run our Unity application through SteamVR, but several of our users are unable to use it due to constant Frame Loss Timeouts, resulting in both our application and SteamVR to crash. We control the systems our clients are using and provide them a dedicated router to connect to the headset with, so the headset is the only device on the network and then the router hardwired to the PC. The crash happens when exiting the main menu and loading into the application proper. In the past we have temporarily solved the issue by lowering VBS's settings, Bitrate down to 20Mbps and the graphics settings to performance, but now the problem persists even with the lowered settings. We have tried updating and degrading graphics drivers and VBS. Using the headset corded is not an option as our program heavily relies on the Eye Tracker and they can't both be plugged in at once. These problems only seem to be effecting certain clients, in house we are running an identical PC + router combo and our unable to recreate the issue. Is there anything other than connection strength that could be causing this error? Is there a way to force the headset to wait longer before termination a connection, similar to using windows registry to make it wait longer on a hanging program?

I am now using Unity with OpenXR Windows to develop for VIVE XR Elite. I found out that I have to use DX11 as the graphics API to make sure streaming works well after I press the 'Play' button in Unity. But I need to use OpenGL for some packages. Once I change the graphics API to OpenGL, I found that the steaming would not work any more. I mean, there is nothing in XR Elite but the Unity works fine according to its Game view. How to use OpenGL while streaming works well? Is it possible?

Issue: Applications sometimes crash during openxr initialization/startup when XR_APILAYER_VIVE_facial_tracking (ViveOpenXRFacialTracking.dll) is loaded. versions: VBS - 1.10.4 ViveOpenXRFacialTracking.dll - 0.1.6.0 Unity - 2021.3 OpenXR plugin - 1.6.0 Repro: Cannot be reproduced consistently. Happens mostly when VBS is running without steamvr and openxr is initialized manually inside unity script. Sample app: Unity application with unity OpenXR plugin v1.6.0 https://docs.unity3d.com/Packages/com.unity.xr.openxr@1.6/manual/index.html One of the OpenXR plugin samples (InterceptFeature) can be used. + simple script (attatched in files) that would start and stop openxr loader on key press. To achieve said crash: 1/ start VBS (without steamvr) 2/ start unity app 3/ press M (StartXR) 4/ if application did not crash kill vrserver.exe and goto step 3 Workaround A: Disable facial tracking layer in system registry. HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ApiLayers\Implicit - set facial tracking dword to something != 0 Workaround B: Disable facial tracking layer using DISABLE_XR_APILAYER_VIVE_FACIAL_TRACKING_1 environment variable XRSwitch.cs Editor.log htc_openxr_facial_tracking_20230118.txt crash.dmp htc_facial_tracking_crash.evtx

Hi, I have a problem with smooth streaming via VBS when I try to use more than 1 headset. Every headset has it's own PC which configuration is enough to work properly - fast loading, good quality etc. But when I try to use second and another headset, I got very slow loading, buffering and worse quality. I use Ubiquiti U6 PRO (a/b/g/n/ac/ax 5400Mb/s) and all headsets are connected to it. My internet speed is around 1Gb/s. I tried multiple options in Ubiquity and VBS, but a problem still occurs. Do you have any Idea what is happening? What else can I do? Or you have your own setup that works?

Hi, I'm trying to connect a Valve Index Controller while using a Vive Focus 3 with VBS. I've connected a Vive Tracker Dongle to the PC but when I go to SteamVR to pair the controller, I get the message 'Looking for your VR hardware' and I can't pair any devices. This set-up works on a different PC running Windows 10 but this issue is occuring on a new desktop running a fresh install of Windows 11. In attachment is an image showing that VBS is connected to SteamVR, the Watchman/Vive Tracker dongle is connected via USB and finally the error message.

Unreal Engine does not provide OpenVR IVRDebug interface in SteamVRPlugin, therefore DriverDebugRequest() is not available for game project use. What you need to do to use DriverDebugRequest() in Unreal Engine: Link your Epic Games account to GitHub account and get authorized by Epic Games. https://www.unrealengine.com/en-US/ue-on-github Modify and rebuilt Unreal Engine according to our GitHub repository https://github.com/ViveSW/UnrealEngine/tree/4.27-DriverDebugRequest You should be able to call DriverDebugRequest() from your Unreal project now! If you want to check our sample project for a Blueprint example: Download sample project : UE 4.27 sample projectDDRTest_Proj.zip Switch the sample project’s Unreal Engine version to your local build Generate project file for sample project Now you can open the sample project and check Level Blueprint for the example of USteamVRFunctionLibrary::DriverDebugRequest() Note: For debug usage, search for “DebugRequest” or “SendV2RParamToServer” In Steam/logs/vrserver.txt to check if DriverDebugRequest() works properly.

Hi, I was previously using the Vive Pro Eye and its eye tracking features, as that has been discontinued I got my hands on a Focus 3 and its Eye Tracking Module, but now Unity is crashing upon loading into any scene that is using the eye tracking. If I disable the eye tracking the crash does not occur, and I narrowed it down to the line "Error result = SRanipal_API.Initial(SRanipal_Eye.ANIPAL_TYPE_EYE, IntPtr.Zero);" in SRanipal_Eye_Framwork.cs that is causing the crash. I have the latest SRanipal SDK (1.3.6.6), the latest SRanipal runtime (1.3.2.0) and using Unity 2020.3.31f1. I have found this guide on setting up face tracking that says I need "SRanipal Runtime Version : 1.3.6.8 or later" which doesn't seem to be out yet. https://forum.htc.com/topic/14087-vbs-pc-vr-how-to-use-facial-tracking-on-focus3/ Does the Vive Focus 3s eye tracking currently support Unity Windows OpenXR over VBS? or am I missing something else?

Hello, we are trying to implement hand tracking for the Focus 3 into our Unity application. It works, but is significantly slower than expected. Our final product targets the Windows platform, the content is then streamed via WiFi 6 to the headsets. Test setup: - Unity 2021.3.6f1 - XR Plug-in Management -> Open XR + Vive Wave OpenXR feature group - Open XR: -> VIVE Wave OpenXR: Hand Tracking - > [active] - Sample scene [HandTrackingExample] from the package: [VIVE Wave OpenXR Plugin - Windows] - A [XR Controller (Action based)] component renders a controller at the wrist position using [Action: devicePosition] As one can see in the video, the hand movenment is smoothed, making it slower and dragging behind the actual position. Is it possible to turn this behaviour off, or work around it? ViveHT_Test.mp4

Hey, I've been trying to get hand tracking working on my Vive Focus 3 in Unity while using VBS. These are the docs I'm currently using Setup — Vive Hand Tracking SDK 1.0.0 documentation. I've not been able to get SteamVR to detect the cameras on the headset through VBS, am I right in assuming that is not supported by VBS currently and that hand tracking is Android only? Thanks in advance for any responses.
