Unreal Engine 5.2 Support

[Brian-HTX]

Hey HTC,

I'm currently working on a new Unreal Engine project and am trying to keep it on the latest Unreal Engine version.  Currently the OpenXR plugin only supports up to 5.1, so I'm wondering is there any ETA on when 5.2 will be supported?

Has anyone successfully gotten the OpenXR plugin to work with 5.2?  I've tried it but ran into issues within the OpenXR module within the engine, so I'm assuming that some changes between 5.1 and 5.2 were breaking from within the engine.

Thanks,

-Brian

@Brian-HTX we are planning to release Vive OpenXR plugin for UE 5.2 in coming weeks. Please stay tuned.

[Brian-HTX]

Hey @KyleC,

Any news on the update?

-Brian

[KyleC]

@Brian-HTX Yes, we have just updated the new integrated plugin for UE 5.1 and 5.2.

Please find it here -  https://developer.vive.com/resources/openxr/openxr-2in1-plugin/unreal/overview/.

[Mike12345]

@KyleC I also need to build for Android in Unreal 5.2 and am unable to.  For both my personal project, and the provided ViveOpenXRGame sample project, on launch I instantly crash with the below call stack.

Both myself and another person at the company are having the problem.  Myself and the other employee are able to use the older Unreal 5.1 plugin just fine with Unreal 5.1.

I followed https://developer.vive.com/resources/openxr/openxr-2in1-plugin/unreal/tutorials/viveppenxrplugininstallation/  except for one change, on ProjectSettings>Plugins>ViveOpenXR i only enabled Cosmos Controller and Focus3 Controller, i disabled FacialTracking/HandInteraction/Passthrough/Wrist Tracker/Scene Understanding because one/more of those were causing separate crashes.

@KyleC I've tried using the 2-in-1 with 5.2 using the plugin and both the sample project.  On launch I instantly crash.  Both myself and a teammate (who tried posting earlier) have failed to utilize the new plugin, despite using the older plugin with 5.1 successfully.

We followed https://developer.vive.com/resources/openxr/openxr-2in1-plugin/unreal/tutorials/viveppenxrplugininstallation/ and also utilize the example project with no luck.  We noticed that the `ViveOpenXRHMD` module has the UPL file set up to look for the plugin as if it's installed as an engine plugin, not a project plugin.  After correcting that, it still did not work.  Any ideas?

[kat7475]

Hi, I am also having this issue in UE5.2 where I have built to android for the Vive Focus 3 and the crash happens on startup, reporting the same issues. I too followed the installation guide for the plugin. I have tried building and launching in not only the sample project but also Unreal Engines VR Template project. I can only assume its a setting somewhere but short of trying everything in the engine I was hoping to find a solution here or on the Epic forums but nothing yet.

From various other posts about how Vive works and it seems like it might be to do with some sort of Stereo layer not supported? But this is kinda a guess. Oculus works completely fine with the OpenXR plugin.

I guess the plugin is fairly new but I feel like I have read that people are able to build a game that doesnt crash so I dont know where I am going wrong. 

Thanks in advance for any help given. Might make a new post about this as well to report the issue 🙂

[Johnson_Wu]

Hi @Mike12345, because the ViveOpenXR plugin highly depends on the ROM runtime, please update your ROM (Navigate to Settings > General > System update in the launcher) then try.

If the issue still exists, please inform us what the System Version of your device is. (Navigate to Settings > General > About > System version).

The problem has been fixed since version number 1.0.999.372 on VIVE XR Elite.

For VIVE Focus 3,  the crash problem will be fixed in the next FOTA (greater than  5.0.999.820).

Thanks!

Hi @Brian-HTX, please update the system ROM and try to launch the app again.

If the problem you encountered still exists, please inform us System Version of your device and the log during launching app. ($adb logcat)

Thanks!

[kat7475]

@Johnson_Wu I'm not seeing the version 5.0.999.850 on VIVE Focus 3 available anywhere, nor is my headset picking up a new update. Any idea when this will drop or how to get it?
