Hi @rvejendla, sorry to hear about your issues. Can you confirm that eye tracking is working as expected in the demo applications?
Please also specify for us if you are using the Native Pico SDK https://developer.pico-interactive.com/sdk
or the Tobii XR SDK https://vr.tobii.com/sdk/develop/unity/getting-started/pico-neo-2-eye/
If using the XR SDK, please specify exactly at which stage the process fails so we can identify the most likely source of the issues.
