Crash when running with VR (OpenXR) after adding LSL4Unity

[beyzadayan]

Hi,

I am using the UXF tutorial project to test the VR headset and I have a question regarding hardware integration.

The tutorial works perfectly when running on my PC using mouse control. However, when I try to run the project with my VR headset (Vive Focus Vision) using OpenXR, the application crashes immediately. I have integrated LSL4Unity into the project to collect external sensor data.

Is there a known conflict between UXF's initialization and the LSL4Unity threads when using OpenXR? Are there any specific best practices for initializing LSL after the XR session has started to avoid this crash?

Thank you for your help!

Hi, unfortunately I don't have the resources or hardware to test and diagnose the issue. However, if any workaround is discovered and implemented I would be happy to review and merge it.

Hi beyzadayan, we extended on UXF to supply a broader open source XR framework for Unity, which includes modules for LSL (extensions on LSL4Unity) and Eyetracking support for multiple headsets. (we discontinued the Vive Focus though, as of bad eye tracking data (see research poster ).

Maybe this will be of interest to you to use for your project.
