I have a VR project in UE 5.4 and want to collect pupil and gaze data for it. I understood I need to install ViveOpenXR plugin for this. However I am not being able to get any data, I see this error in my output log: “LogHMD: Warning: Required extension XR_HTC_eye_tracker is not available”. the sr-runtime has green eyes and eye calibration has been done. Here are the versions of things I have installed:
UE 5.4
ViveOpenXR plugin: 2.5.0
SRanipal: 1.3.6.12 installed through VIVE Console
Headset: Vive Pro Eye
I want to first make sure I am not running into compatibility issues and to know if I should completely give up. If you have made it to work please please let me know. I appreciate it
