The best object scanner for a standard android cell phone I've found is vuforia's object scanner. I used it in the past to great effect, and want to scan models again.


however, I can't download it anywhere.


can someone please link me to the apk? even if it's an older legacy version not updated, it should still work. The alternatives are crap.



Hey there,


Object Targets were deprecated last year and with that, the Object Scanner app. To use similar features I recommend using our Model Targets together with scanning 3D models with apps like Polycam.

iPhone 14 heating problem

Hi, I recently encountered a problem with an iPhone 14 pro max. The phone gets very hot when my application uses Vuforia. It's a little strange because on other devices (iOS/Android) it doesn't heat up as much. Do you think there could be a problem between Vuforia and the new apple phone?

Hey there,


Could you share additional findings and try to build our Core Samples to validate that the device gets extremely hot even with those samples? The samples can be found here:

Android/Unity Black Screen


Hello all. I recently started development with Vuforia on Unity and intend to target mobile devices. I am using an Android device now for testing. The app loads, the Unity splash screen shows up, and in the top right corner of the device, I can see a camera icon or a green dot, which seems to indicate that the app does indeed have access to the camera. However, all I see is a black screen. I have tried, but to no avail, the leads mentioned here: and here: (with the exception of disabling ARCore in editor since Unity doesn't let me.) Since I am very new to Vuforia and AR development as a whole, not that well versed in Android deployment and only intermediate in Unity development, I'm a bit at a loss when it comes to debugging such problems. Is there something I'm missing? Any help would be appreciated.

Hey there,


Did you follow the steps of the article you shared? Can you share why you cannot disable ARCore in the editor? This is possible through the Vuforia Configuration file.


Kind regards,

Patrick Scheper

Thanks for the reply. In the Unity UI, trying to select DONT_USE on the ARCore Requirement dropdown automatically sets it back to OPTIONAL. It also checks the Include ARCore Library checkbox underneath if it's unchecked.

Where can I find the configuration file?

Hey there,


No problem! Which version of Vuforia are you using?

iphone cannot recognize image



My project could be built successfully on Xcode, but it can not recognize the pre-set image while I open the Unity app on my Iphone. However, it could work well on my mac.

There are several reminders when I run it. Could you help me to check this problem? Which is the main problem that I have to tackle?

The version of my Unity is 2021.3.16f1.

Hey there,


I would suggest trying to build our Core Samples project and see if you experience the same issues:

In my project was the solution to rename it, because I named my project Vuforia as well.

Accessing images on iOs with Unity Web Request - Connection Error

Hi guys,

I'm implementing an AR application where I need to load images saved on my persistentDataPath: on accessing such images through the Unity Web Request methods (I upgraded the deprecated WWW class) , a connection error is spawn. I attached the logs files from XCode in a zip folder. Here is part of my code (I  think it could be related to the URL where the images are located and how iOs converts/read it)

public IEnumerator CreateGuideViewButton()     {         Buttons = new List<Button>();         mContent = GameObject.FindGameObjectWithTag("Content");

        string mPath = Application.persistentDataPath + "/BH Inspection Plan/Vuforia Dataset/" + FileExplorer.mFileName + "/dataset";         mInfo = new DirectoryInfo(mPath);         mFiles = mInfo.GetFiles("*_1.png");


        int mPNGs = mFiles.Length;

        for (int i = 0; i < mPNGs; i++)         {             string mName = i.ToString();

            Button mPrefabButton = Resources.Load<Button>("MyButton") as Button;              Button mMyButton = Instantiate(mPrefabButton);    = mName;


            if (i % 2 == 0)              {                                  mMyButton.GetComponent<RectTransform>().localPosition = new Vector3(mXEven, mYEven, 0);                 mMyButton.GetComponent<RectTransform>().sizeDelta = new Vector2(side, side);                 mYEven -= 450;

                                string mImagePath = Path.Combine(mPath, (FileExplorer.mFileName + "_viewpoint_000" + i + "_1.png"))


                UnityWebRequest www =  UnityWebRequestTexture.GetTexture(mImagePath);                 yield return www.SendWebRequest();                

                if (www.result == UnityWebRequest.Result.InProgress)                 {                     continue;                 }                 else if (www.result == UnityWebRequest.Result.ConnectionError)                 {                     Debug.Log(www.error);                     yield return false;                 }                 else if (www.result == UnityWebRequest.Result.Success)                 {                     texture = DownloadHandlerTexture.GetContent(www);                 }

                               int width = texture.width;                    int height = texture.height; 

               if (height >= width) 

                {                     RawImage mPrefabImageHeight = Resources.Load<RawImage>("MyImageHeight") as RawImage;                     RawImage mMyImage = Instantiate(mPrefabImageHeight);                     mMyImage.gameObject.transform.SetParent(mMyButton.transform);                     mMyImage.GetComponent<RectTransform>().localPosition =;                     mMyImage.GetComponent<RawImage>().texture = texture;                  }                 else                 {                     RawImage mPrefabImageWidth = Resources.Load<RawImage>("MyImageWidth") as RawImage;                     RawImage mMyImage = Instantiate(mPrefabImageWidth);                     mMyImage.gameObject.transform.SetParent(mMyButton.transform);                     mMyImage.GetComponent<RectTransform>().localPosition =;                     mMyImage.GetComponent<RawImage>().texture = texture;                  }



Thanks in advance!


Phones compatible with ObjectScanner

Hello Vuforia Community!


I previously used the ObjectScanner app to map a target object. I currently have a Samsung Galaxy 10, but am not able to find the Vuforia ObjectScanner app through the GooglePlay app store. Is there another app that Vuforia has developed that has the ObjectScanner capabilities? Or has that functionality been integrated into a different Vuforia app?


Thank you very much for your help!



Unfortunately, the Object Targets feature and the Object Scanner companion app were both retired in Engine SDK 10.7.

Please see our release notes for more details:
