OpenXR-SDK-Source VS unity-webxr-export

I‘d recommend to take a look at the Hello_Xr sample in the OpenXr repository here: https://github.com/KhronosGroup/OpenXR-SDK-Source/tree/master/src/tests/hello_xr

I've dug into it some more and the file is from Monado, which I had compiled with debug symbols due to similar issues having happened before. xr_generated_loader.cpp:152 is from OpenXR-SDK-Source, also compiled with debug symbols for the same reason.

There is only one mainstream OpenXR loader implementation, the one from Khronos. Older OpenXR loader versions did export extension functions "by accident", but it was fixed quite a while ago https://github.com/KhronosGroup/OpenXR-SDK-Source/commit/d14bd22ae3a64d6bcb3a79a6119f35ad0a2d3110

OpenXR API layers are like Vulkan API layers. There are two API layers that are provided by default, one to dump api calls and one to validate api calls. Those layers are now included in the openxr_loader_windows-*.zip on the OpenXR-SDK-Source releases page but you probably have to set the XR_API_LAYER_PATH environment variable or some registry key on windows for the loader to find them.

De-Panther actively maintains an up-to-date version of Mozilla's original exporter at https://github.com/De-Panther/unity-webxr-export. I've used it several times in the past for Unity-related WebXR projects.

If so, this will be compatible with Unity WebXR Explorer ?

We are the Indian Sonic Research Organization, and we would like to present Zoophony VR: An online Spatial Audio experience (Made in Unity with De-Panther's WebXR plugin).

The WebXR spec is fairly well-defined, but has yet to be fully implemented into Webkit (the browser engine Safari uses). Currently the best way of creating WebXR content with Unity is using an up-to-date exporter such as this one by De-Panther, but there is currently no way to view WebXR content on iOS outside of Mozilla's viewer, which is unfortunately somewhat outdated now.

I used De-Panther's fork of the Unity WebXR Exporter, originally by Mozilla. Unlike the original it's still being actively maintained and improved, I'll likely keep using it in future WebXR projects with Unity.
