Prefab has missing scripts - both the GreenCar and RedCAr. After opening the prefab for the cars, I tried changing/assigning scripts, but there are no options to be selected. What to do?

hi, may I know where you got your import objects/model?

Hi! When trying to build for the first time I receive an error asking to select the development team even thought is already selected. Do you have any idea how to fix it? I’m not able to find a solution

For those having the "BLACK SCREEN PROBLEM" you may have a "Vulkan" problem. Meaning in the Player Settings option - Scrool down to Graphics API's - remove Vulkan option ( Keep Open the GLES3) That Should fix your problem.

Está genial el video 👌👌, te quería preguntar si tienes canal en español?

Great Video. but may I know why there is some jittering when your cars are spawn? I am having the same issue.

Thanks for your tutorial, very helpful! I currently facing a problem, when I done the part about 4:23 everything works fine But when I moving to the 11:44 to do multiple image track and build my game to my android device, the game will crash immediately I've try two version of AR Foundation ( and Unity ), but both version also facing this problem 1: Unity 2022.3.0 + AR Foundation 5.0.7 2: Unity 2021.3.23 + AR Foundation 4.2.9 And the Scripting backend is already set to iL2CPP, also the Graphics APIs is only OpenGLES3 with Linear color space. Hope I can get some help, and sorry about my poor english.

What should i do if i want this project as WebGL. I tried switching platform and building it and when i run it, I get a black screen with prefabs hovering at the left side. I want to make a WebAR Project using this. Can someone help?

Here is the code for MultipleImagesTrackingManager.cs: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.XR.ARFoundation; using UnityEngine.XR.ARSubsystems; public class MultipleImagesTrackingManager : MonoBehaviour { [SerializeField] private GameObject[] prefabsToSpawn; private ARTrackedImageManager _arTrackedImageManager; private Dictionary<string, GameObject> _arObjects; // Get the reference of ARTrackedImageManager private void Awake() { _arTrackedImageManager = GetComponent<ARTrackedImageManager>(); _arObjects = new Dictionary<string, GameObject>(); } private void Start() { // Listen for any change in TrackedImageManager _arTrackedImageManager.trackedImagesChanged += OnTrackedImageChanged; // Spawn the game objects per image and hide them foreach (GameObject prefab in prefabsToSpawn) { GameObject newARObject = Instantiate(prefab, Vector3.zero, Quaternion.identity); newARObject.name = prefab.name; newARObject.gameObject.SetActive(false); _arObjects.Add(newARObject.name, newARObject); } } private void OnDestroy() { _arTrackedImageManager.trackedImagesChanged -= OnTrackedImageChanged; } private void OnTrackedImageChanged(ARTrackedImagesChangedEventArgs eventArgs) { // Identify the change on the tracked image foreach (ARTrackedImage trackedImage in eventArgs.added) { UpdateTrackedImage(trackedImage); } foreach (ARTrackedImage trackedImage in eventArgs.updated) { UpdateTrackedImage(trackedImage); } foreach (ARTrackedImage trackedImage in eventArgs.removed) { _arObjects[trackedImage.referenceImage.name].gameObject.SetActive(false); } } private void UpdateTrackedImage(ARTrackedImage trackedImage) { // Check tracking status of tracked image if (trackedImage.trackingState is TrackingState.Limited or TrackingState.None) { _arObjects[trackedImage.referenceImage.name].gameObject.SetActive(false); return; } // Show, hide, or position the GameObject on the tracked image if (prefabsToSpawn != null) { _arObjects[trackedImage.referenceImage.name].gameObject.SetActive(true); _arObjects[trackedImage.referenceImage.name].transform.position = trackedImage.transform.position; } } }

Hi, is there a way yo updated Xr References Image Library With Adressble? I can download and update but library not working correctly when i update with adressbles (I use Ar foundation 5.0.7)

it is great!

*promo sm*

Great video, I have a question, how to unlock rotation in GameObject Spawned by Image Tracker? I am using Lean Touch to change Scale that is allowed but Rotation and Position are Locked.

Hi i followed you tutorial, but i don't know why the 3D objects don't spawn when i track the image, can you help me?

Could you by any chance put the Script in the description or here in a comment? I'm trying to follow your steps but the script doesn't work for me (I definitely have some typo on the code). Thanks for the video!
