Hi @rvejendla, I am afraid that we do not understand the issue you are trying to communicate. Can you please confirm firstly that you follow each step within the tutorial @ https://vr.tobii.com/sdk/develop/unity/getting-started/pico-neo-2-eye/ and that everything works as it should here?
Thereafter try to use our workflow in your project and let us know the steps you followed. Thanks.
