Hi!
What it does internally is a bunch of raycasts with scoring.
It could be that you use multiple cameras and don’t call https://tobii.github.io/UnitySDK/scripting-api#tobiiapisetcurrentuserviewpointcamera
Otherwise I would suggest to add more logging inside GazeFocus.cs and MultiRaycastHistoricHitScore.cs
Please let me know if it resolved the problem 🙂
