Hi @RMFoley92 did you get the chance to check this guide ?

 

[OnApplicationFocus / OnApplicationPause never called]

Hi @EliotR

The real "suspend" happens after the HMD screen is off for 3 minutes so the OnApplicationPause will only fire then.

Hello,

Please package your content in shipping build to prevent the crash.

[Absolutely can NOT get hand tracking working in Unity for Vive XR Elite]

Hi @Radicals,

Based on the images you shared, I believe that you are mixing both Wave SDK and Wave OpenXR. You should be using on of the two.

If you are using the Wave SDK then in you XR Plugin-Management you should have the WaveXR tick box ticked (The WaveXR settings will not affect OpenXR content). Otherwise, if you are using OpenXR in you XR Plugin-Management you should have the OpenXR tick box ticked similar to the picture you shared and enable the Hand tracking feature from the OpenXR Feature Groups, ref image below.

Hi @Maks

You will need to submit/publish your app on the app store https://business.vive.com/appstore

[Size thumbnail in library Focus 3]

Hi @Maks

The Android APK only includes app icon and that is what you see displayed in your library. The Scaled-up icon (thumbnail) is from the server side since it is the thumbnail of the store app. So, you will need to submit your app to the store to get the icon to fill the entire area.

[Vive Tracker OpenXR Support Unreal Engine]

Hi @JonMart

Is the tracker showing in SteamVR (ref image below) ?

What tracker Role and what SteamVR version are you using ? You can refer to the below image showing my working setup.

 

Thanks

 

[Handtracking in Unity Smoothing Problem]

Hi @NMY

Please update your VIVE Wave OpenXR Plugin – Windows to version 1.0.7 to fix the hand tracking delay issue.

[Unity Controller Detection]

So I guess you are using the VIVE Wave OpenXR Plugin - Windows correct ? You can download the OpenXR "Controller Sample" from the package manager.

Also make sure that you have the following OpenXR Settings (under Project Settings > XR Plug-in Management > OpenXR )

VIVE Wave OpenXR is enabled under OpenXR Feature Group and HTC Vive Cosmos Controller Support is selected as the Interaction Profile.

[Unity Controller Detection]

Hi @nsosa,

In order to run application directly from VIVE Focus 3, you will need the WAVE SDK or OpenXR for Mobile VR to create VR content for Android (APK file). Kindly check the VIVE WAVE SDK and VIVE OpenXR For Mobile documentation as they contain all the needed information to get you started. You can build your content with Unity ,Unreal Engine or natively.

You can also run SteamVR or PC VR OpenXR content on VIVE Focus 3 via VIVE Business Streaming. VIVE Business streaming allows you to steam PC content to VIVE Focus 3 through USB Cable or Wifi.

Hi @tonkso

I sent you a email please check it and respond when possible.

Thank you.

[unreal 4 - sometimes controllers don't work ?]

Hi @DDFS,

From my understanding is that in some cases you are unable to use you controllers? From your description, the controller setups should be fine  by using the motion controller component and you should be able to see the controllers at all times.

Make sure VIVE Wave is the only VR pluging enabled. Turn off all other VR plugins especially OculusVR and SteamVR to prevent conflict.

Is OpenXR plugin enabled ?

You can Direct Preview available in Wave SDK if you would like to test directly from the editor.

 

[Unreal Engine Application installs as 2D app on Focus 3 and not A VR app.]

Hi @KieranLatham,

Please make sure you have Start in VR selected.

You will also need the WaveSDK plugin in order to build content for Focus 3. You can download the latest Wave SDK here https://developer.vive.com/resources/vive-wave/download/latest/

In case you already did this Make sure VIVE Wave™ is the only VR plugin enabled. Turn off all other VR plugins (especially OculusVR and SteamVR) to prevent conflicts.

I would also recommend you check our Unreal Engine Getting Started Guide.

[Vive Focus 3 - Unreal v4.27]

Hello, 

A BETA program is available to support OpenXR content development using Unreal Engine 4.27.

Kindly follow the link below for more information.

 

[Setting the larger icon for the Focus 3 menu in Unreal]

Hi @nbaja

The Android APK only includes app icon and that is what you see displayed in your library. The Scaled-up icon (thumbnail) is from the server side since it is the thumbnail of the store app. So, you will need to submit your app to the store to get the icon to fill the entire area.

Hope this helps !

[Unity : Unable to enter Play Mode with headset.]

Hello @dev_imag-ing,

Just to clarify you are not able to use Direct Preview at all ? If so, can you make sure you have enabled WaveXR under XR Plugin-Management for PC platform aswell.

Regarding, Vive Business Streaming it should work fine. Try to switch to PC platform to test.

Hope this helps ! 

 

[Vive Focus 3 low performance in UE4 build]

Hello @aiddun,

Focus 3 has larger framebuffer, eye-buffer size, wider FOV, different refresh-rate so there might be a performance difference based on same content running on Quest 2. We recommend setting Pixel Density to around 0.8 (Value could change depending on content) to lower the eye-buffer size and match the resolution of Quest 2 hence increase FPS.

Recently we had optimization for Shader on our Wave SDK 4.4.0 and may gain around 5~10% GPU performance improvement.
