Hi @nikepupu

This is a bug in the code that I'm pending to fix... I hope to have a solution soon. Sorry for the inconvenience

[nikepupu]

Is there any update on the status?

[Toni-SM]

Not yet but please check NVIDIA forum https://forums.developer.nvidia.com/t/external-extensions-openxr-compact-binding-for-creating-extended-reality-applications/192173

Hi @nikepupu

It seems that the problem is when an XR instance is destroyed by method xrDestroyInstance. This issue is already reported in the Steam Community: https://steamcommunity.com/app/250820/discussions/8/3114772813482874960/

I am working on a solution for it...

[nikepupu]

Hi, I am happy to help out if you need someone to play around with it. I think it's going to be quite useful for my research project.

@Toni-SM Hi, Is there any progress on Linux?

after launching your example code,

from semu.xr.openxr import _openxr
_openxr.release_openxr_interface(xr)

Then IssacSim crash occurs (SteamVR return to SteamVR Home)

Thanks!

Hi @PARKBONG

Sorry, that's a known problem, Unfortunately, I haven't had the time to look at it in depth. I hope I can fix it although it's not clear to me when...

All code and steps to compile it are in the repository, in case someone wants to fix it or contribute in some other way 😁
