Question Prefabs not changed when reference image changed

Hi,

I setup whole project and that is fine. But I'm sucked now with script.

I have 26 images in library and 26 prefabs for each of them.
But I get only one, always. All images trigger first prefab.
And sometimes nothing happened.

I attached 5 images of that 26.

I need help to get this proper to work.
I just need to each image trigger each prefab.
Without any UI, without any special options or functions.
Just to shot proper prefab for proper image.

Here is script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.XR;
5. using UnityEngine.XR.ARFoundation;
6.  
7. [RequireComponent(typeof(ARTrackedImageManager))]
8. public class ImageTracking : MonoBehaviour
9. {
10.     [SerializeField]
11.     private GameObject[] placeablePrefabs;
12.     private Dictionary<string, GameObject> spawnedPrefabs = new Dictionary<string, GameObject>();
13.     private ARTrackedImageManager trackedImageManager;
14.     private void Awake()
15.     {
16.         trackedImageManager = FindObjectOfType<ARTrackedImageManager>();
17.         foreach (GameObject prefab in placeablePrefabs)
18.         {
19.             GameObject newPrefab = Instantiate(prefab, Vector3.zero, Quaternion.identity);
20.             newPrefab.name = prefab.name;
21.             spawnedPrefabs.Add(prefab.name, newPrefab);
22.         }
23.     }
24.     private void OnEnable()
25.     {
26.         trackedImageManager.trackedImagesChanged += ImageChanged;
27.     }
28.     private void OnDisable()
29.     {
30.         trackedImageManager.trackedImagesChanged -= ImageChanged;
31.     }
32.     private void ImageChanged(ARTrackedImagesChangedEventArgs eventArgs)
33.     {
34.         foreach (ARTrackedImage trackedImage in eventArgs.added)
35.         {
36.             UpdateImage(trackedImage);
37.         }
38.         foreach (ARTrackedImage trackedImage in eventArgs.updated)
39.         {
40.             UpdateImage(trackedImage);
41.         }
42.         foreach (ARTrackedImage trackedImage in eventArgs.removed)
43.         {
44.             spawnedPrefabs[trackedImage.referenceImage.name].SetActive(false);
45.         }
46.     }
47.     private void UpdateImage(ARTrackedImage trackedImage)
48.     {
49.         string name = trackedImage.referenceImage.name;
50.         Vector3 position = trackedImage.transform.position;
51.         Quaternion rotation = trackedImage.transform.rotation;
52.  
53.         GameObject prefab = spawnedPrefabs[name];
54.         prefab.transform.position = position;
55.         prefab.transform.rotation = rotation;
56.         prefab.SetActive(true);
57.  
58.         foreach (GameObject go in spawnedPrefabs.Values)
59.         {
60.             if (go.name != name)
61.             {
62.                 go.SetActive(false);
63.             }
64.         }
65.     }
66. }

I need help from you. Please. Thank you.

 

Markers are too similar I think.
