Hi @rvejendla, If you carefully follow our getting started guide as linked above, it should work unless so perhaps a step has been missed somewhere?
It is difficult to advise you further without additional information.
A couple of things to consdier:
– Make sure gaze aware objects have a collider AND implements the IGazeFocusable interface
– Make sure the TobiiXR Initializer prefab is set exactly as in the working scenes
– we would recommend also adding a cube with the HighlightAtGaze script attached to see if it highlight when looked at
Try it out and let us know how you get on. Best Wishes.
