Eye Tracking issue with Meta Quest Pro in Unity (Meta Core SDK)

[curby.980441]

Hello,

I am working on a Unity VR project and I am currently using the Meta Quest Pro. I want to collect eye and facial data from the user so I created a script to access the data from OVREyeGaze, but I keep receiving this same error of the Eye tracking not being enabled (checking if OVR.eyeTrackingEnabled is true). I have checked the necessary boxes in OVRManager and enabled the beta settings for the Eye tracking and in the Meta Quest Pro's settings. Please let me know if I am doing anything wrong or if I missed something. I would be more than happy to provide more information.  I will attach my code for the eyetracking.

using System;

using System.IO;

using UnityEngine;

/// <summary>

/// Logs eye tracking data from OVRPlugin to a CSV file.

/// </summary>

public class EyeTrackingLogger : MonoBehaviour

{

    public string LogFileName = "EyeTrackingLog.csv"; // File to save logs

    public float LogInterval = 0.1f; // Time between log entries in seconds

    private float _nextLogTime;

    private StreamWriter _csvWriter;

    private bool _isLogging;

    void Start()

    {

        // Automatically start logging when the game starts

        StartLogging();

    }

    void Update()

    {

        // Log data periodically based on LogInterval

        if (_isLogging && Time.time >= _nextLogTime)

        {

            LogEyeData();

            _nextLogTime = Time.time + LogInterval;

        }

    }

    void OnDestroy()

    {

        // Stop logging and clean up resources when the object is destroyed

        StopLogging();

    }

    /// <summary>

    /// Starts logging eye-tracking data to the CSV file.

    /// </summary>

    private void StartLogging()

    {

        if (!OVRPlugin.eyeTrackingEnabled)

        {

            Debug.LogError("Eye tracking is not enabled. Ensure it is configured in the Oculus settings.");

            return;

        }

        try

        {

            _csvWriter = new StreamWriter(LogFileName);

            _csvWriter.WriteLine("Timestamp,Eye,Confidence,PositionX,PositionY,PositionZ,RotationX,RotationY,RotationZ,RotationW");

            _isLogging = true;

            Debug.Log($"Eye tracking logging started. Writing to: {LogFileName}");

        }

        catch (Exception e)

        {

            Debug.LogError($"Failed to start logging: {e.Message}");

        }

    }

    /// <summary>

    /// Stops logging and closes the CSV file.

    /// </summary>

    private void StopLogging()

    {

        if (_csvWriter != null)

        {

            _csvWriter.Close();

            _csvWriter = null;

        }

        _isLogging = false;

        Debug.Log("Eye tracking logging stopped.");

    }

    /// <summary>

    /// Logs the current eye-tracking data.

    /// </summary>

    private void LogEyeData()

    {

        var eyeGazesState = new OVRPlugin.EyeGazesState();

        if (!OVRPlugin.GetEyeGazesState(OVRPlugin.Step.Render, -1, ref eyeGazesState))

        {

            Debug.LogWarning("Failed to retrieve eye-gaze state.");

            return;

        }

        foreach (OVRPlugin.Eye eye in Enum.GetValues(typeof(OVRPlugin.Eye)))

        {

            var eyeGaze = eyeGazesState.EyeGazes[(int)eye];

            if (!eyeGaze.IsValid || eyeGaze.Confidence < 0.5f) // Adjust confidence threshold as needed

            {

                continue;

            }

            var position = eyeGaze.Pose.Position;

            var rotation = eyeGaze.Pose.Orientation;

            string logEntry = $"{Time.time},{eye},{eyeGaze.Confidence},{position.x},{position.y},{position.z},{rotation.x},{rotation.y},{rotation.z},{rotation.w}";

            _csvWriter.WriteLine(logEntry);

        }

        _csvWriter.Flush(); // Ensure data is written to the file immediately

    }

I posted a community post on there and received no response. When i try to load the page sent to me it doesn't seem to fully load? I've tried everything to fix this issue but I am unsure what is wrong. Is there a way to contact someone to fix my issue?
