Enabling OpenXR

          *** note: with the latest update OpenXR is already enabled for VIVE Cosmos ***

 

Development For UE4 Developers:

UE4 developers can start with this project:

Documentation for OverrideOpenXRPlugin Project.pdf
OverrideOpenXRPlugin.zip

UPDATE:  ViveOpenXRPlugin_UE426.zip

 

• New Vive OpenXR Unreal Plugin to support Unreal 4.26
• OpenXR.Documentation is inside the package.

 

Development For Unity Developers:

Note: Unity has released a preview version of the Open XR plugin for Unity 2020.2
Please see the related post for detailed information and for the download link to the Vive Cosmos Controller Feature for Unity OpenXR:
 https://forum.vive.com/topic/9141-vive-cosmos-controller-openxr-feature-for-unity/

Sample OpenXR applications:  (additional examples forthcoming in forum)

If you're interested in simply trying out an OpenXR sample app with the Vive Cosmos,  Here is a sample build:  

CosmosControllerSample(Unity).zip

There are also third party applications already available. One example is  Blender which supports OpenXR (inlcuding the Vive Cosmos OpenXR preview runtime) within the Blender application which helps designers test their creations without leaving the Blender editor:

Additional Notes:
Please note if you are having issues, please check or install the latest Visual C++ redistributable found here: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

Stay tuned for additional documentation and examples and updates.

Updated to day and now Openxr dont work on Microsoft flight simulator 2020 vr. why i dont know.. please help

 

[cusa123]

I also have some problems using openxr the viveport gives me different colors on each screen and many times. It also costs horrors to start or enter some app or game but not always. I think it will be steamvr 1.15.12.

[dario]

@cusa123, sorry it's not clear, are you using the OpenXR preview runtime for Cosmos or are you using SteamVR? (both won't run at the same time)

@Patrik Did you mean you recently updated the preview runtime or MSFS 2020 or both? I thought VR support for MSFS 2020 was coming end of Dec. Early previews may be limited to specific devices - did you have it running earlier or with SteamVR's OpenXR runtime?

Lo siento Darius, si estoy usando el modo de desarrollador htc (2.0.15.3).

Hi Dario.. I have fixed this problem. I am a closed Vr beta tester for ms2020 and it works fine...

The issue was : when i run the openxr with the vive cosmos beta it was working really really good. Then a update came and it stop working. So i had to go beck to standard update to make it work.

It was like Msfs2020 conflicted with the vive cosmos openxr. I will try more out if you want log files please explain where to get it and i can send it ..

Kind regards Patrik

Thanks Patrik, for the update.  Please feel free to send me a private message to send logs.

Hi, I see that for now Direct3D is the only graphics API supported by the Vive OpenXR runtime, does HTC plan to support others APIs like Vulkan anytime soon?

@Gianmarco

Please see the updated list of extensions, we've added opengl support recently. Thanks for the feedback, we'll get back to you when we can announce additional support.
