OpenXR toolkit not working

[Lunastras]

I am running OpenXR on a custom engine and the integration I have is straight from the HelloXR example. I have tried running my program and HelloXR using the OpenXR toolkit and on one machine it fails to run, while on another it crashes. This is with the latest version of the toolkit and latest version of HelloXR/Varjo Base/OpenXR libraries. Here is the log that is printed on the machine where it just runs without crashing:

Anybody knows why “Unsupported graphics runtime” is printed? As a side note, my program is running on opengl.

This is probably an issue with the “OpenXR Toolkit” layer, which is third-party software not maintained by the working group.

@mbucchia might be able to help.

OpenXR Toolkit only supports D3D, there is your issue.

[Lunastras]

Thank you for letting me know! I really thought I did something wrong in my program.

OpenXR Toolkit only supports D3D, there is your issue.

Out of curiosity, why does it provide information that it supports OpenGL then?

Thats the OpenXR Runtime (the log clearly says “Runtime supports…”).

OpenXR Toolkit, which is an optional add-on not related to your runtime, will only work with D3D11/12.
