Hello,
Can anyone help me with this error. I tried to build the face tracking on android.

hello dilmerv

I am creating a application for jewelery my requirement is track jewelery on ear , nose ,head and neck for all jewelery.
Can you please it is possible to make application through ARFoundation

Please reply me i am in need.

thank you dilmerv !
you are doing a great job !

If you run the PeopleOcclusion scene on the iPad Pro (may also be an issue on other devices, but I don't have one to test), the stencil is offset from the detected body part.

Hi Dilmer Valecillos,
I'm a beginner in the Unity AR form the background of UI/UX. I saw your youtube video and learning the Unity AR.
I have downloaded the code from https://github.com/dilmerv/UnityARFoundationEssentials and trying to run the project in Unity but not a success.
Error (Assets\Scripts\ReferencePointManager.cs(8,26): error CS0246: The type or namespace name 'ARReferencePointManager' could not be found (are you missing a using directive or an assembly reference?))
I have added the screenshot for the error's Please help or advice.
Thanks

Hi, my question is: Instead of dragging prefab into the inspector and instantiating it, how can I place a gameObject in AR scene?

So I would like to load a gameObject from a scene into my AR scene. The AR scene will automatically detect for the plane. Once a plane is detected, the gameObject loaded should be automatically placed on the plane. The code I found uses prefab and instantiate like this

placedObject = Instantiate(placedPrefab, arPlane.transform.position, Quaternion.identity);
However, if the placed prefab is of type gameObject (basically I dragged the gameobject loaded), it didnt work. the gameobject was floating in air instead of following the detected plane. Do you know whether it is possible to achieve my desired scenario? Why is the position of gameobject wrong when I drag an existing gameobject in the scene instead of prefab?

Thank you in advance!

Below is my code but it didnt work:

[SerializeField]
 private GameObject placedPrefab;

 [SerializeField]
 private GameObject placedObject;

 [SerializeField]
 private ARPlaneManager arPlaneManager;

 void Awake() 
 {
     dismissButton.onClick.AddListener(Dismiss);
     arPlaneManager = GetComponent<ARPlaneManager>();
     arPlaneManager.planesChanged += PlaneChanged;
 }

 private void PlaneChanged(ARPlanesChangedEventArgs args)
 {   
     if(args.added != null && placedObject == null)
     {
         ARPlane arPlane = args.added[0];
         //placedObject = Instantiate(placedPrefab, arPlane.transform.position, Quaternion.identity);
         placedPrefab.transform.position = arPlane.transform.position;
     }
 }

I am working on a image tracking project where I want to scan an image and show the prefab on a set position in the world. Eg Vector3(0, 3, 15) in the direction the image target points to. Ive been looking into this project and it works really well for me except that it looks like the prefab show up in the direction of the device and not the rotation of the image target. When I stand on the left side of the image and scan, id like the prefab to show up on the set position to the left of me, and if I stand with the image in front of me the prefab should show up in front of me. I am testing on Android and ARCore works the way I described out of the box. Is this a feature you would want to implement or help me solve? Thanks

sir,it can't work well on android, is it a problem with my setup, or is it not supported by android?

How can i achieve like this video on plane tracking ?

I am facing multiple issues with things as 'Input System', 'AR Human Body Manager','AR Reference Point Manager', 'AR Occlusion Manager', 'XR CPU Image', 'AR Human Bodies Changed Event Args', 'Configuration Chooser', 'Configuration Descriptor', 'Feature', 'Configuration', 'XR Human Body Pose 2D Joint', 'AR Human Body', 'Camera Facing Direction'. I googled it and read the documentation and found that these error occurs due to use of different version of AR-Foundation, AR-Core XR Plugin, AR-Kit XR Plugin, AR-Kit Face Tracking , also you are using preview packages for the above 4, so it's my humble request that please let me know the exact version that you are using, and lastly I am using Unity 2020.1.

Im trying to make a augmented reality project with unity engine when i host it in GitHub its not accessing the camera permission can anyone please help me out i don't need any plugins or sdks

Running Unity3d : 2019.3.1.1

For some reason, I keep receiving the error below

error CS0246: The type or namespace name 'ARHumanBodyManager' could not be found (are you missing a using directive or an assembly reference?)

Hope you can help

i have unity 2020 , i have started the project i had several error in code :

Surprised to see the back camera is used in the FaceTrackingMesh scene when building for IOS and running on an iPhone 7. On an iPhone 11 it uses the Front Facing camera correctly. Does Unity exposed a setting for this?

Hello
If you have could you share the fbx format of skeleton so i can make some changes and see how it is fitting?

how to change measurement to Meter? I try delete measurement factor and assume default Cube Scale in unity is 1:1 meter in real world, but I think Im wrong. Can Anyone help?

Hi,
I have taken one of the example scene (ImageTrackingRuntimeSave) from the UnityARFoundationEssentials project for adding images to XRImageLibrary at runtime.

I have made some changes on that code, like instead of adding the images from unity i loaded it from persistence path, it was working fine initially. After some point of time it was giveing some issue on while adding the images to the library.
Even if i load images from my asset folder to XRImageLibrary it is give me an error.

This is the error which i am getting from the script.
System.NullReferenceException: Object reference not set to an instance of an object at DynamicLoading+<AddImage>d__6.MoveNext () [0x0009a] in

When i further debug the code its showing error in texture format line, but in my project i have made those images to Read/Write enable and format to RGBA32.

But still i am getting the error.
Could someone explain me how to solve this?

I am using the following: Catalina OSX, XCode 11 Beta, iPad_9.7 iOS 13 Beta, Unity 2019.1.6, Visual Studio for Mac latest

On XCode (set to Automatic license and team)..Builds..and runs on iPad but the camera doesn't face me and texture does not appear.

I get the following error in XCode:

Not sure if a script or component is missing in Unity or there is a setting that needs to be set. Everything in the UI seems to look good.

Thanks,

Hello,
please help me to fix this error, it showing project not connected to unity cloud while i try to open it.

I got a problem, when camera starts, the two objects appears in 0,0,0 position,,, why if i didnt found the marker yet? but when i found a marker its relocated position and scale and everything works ok... just in the begining every prefabs invoke in scene auto.

Hi Dilmer,

first thanks for your work, you are really helpful in helping us. I have a question, do you think that using people occlusion (and hands detections?) is possible to detect the touch of an virtual object?

I need to implement something like vuforia virtual buttons but i cannot use vuforia (it isn't compatible with cardboard anymore)

Thanks
Andrea

Hi Dilmer,

Normally I use Vuforia but through the help of your videos i am learning AR Foundation. But i have a question: with Vuforia you can drag/drop by example a sprite on the image marker and position it exactly on the X,Y position you want. When you scan the imagetarget the sprite will be positioned exactly on the X,Y position on the recognised imagetarget.

Is this also possible with AR Foundation Image Tracking? And how can this be accomplished in the Unity Editor?

For customers in the past we used Vuforia to by example show video's and AR buttons on certain position on a poster and when the user scans the poster all AR elements are shown on the correct position on the poster. I like to reuse this functionality but in this case with AR foundation.

I am looking for a method to extract the face tracker's texture and apply it to the face mesh 3d model. Thanks, lots of love..

Hello @dilmerv,

Thanks a lot for your great demo! However, as a newbie to this fascinating technology, I encounter problem in building the app due to the following errors, no matter what versions of unity I have tried (2023.2.3f1, 2022.3.13f1, 2021.3.32f1, 2020.3.34f1, 2019.2.2f1) in mac intel.
I want to try Measurement scene, but I cannot even enter the play mode since the console required me to fix the errors first. Here are the errors I have got from 2023.2.3f1.

All compiler errors have to be fixed before you can enter playmode!

Pleas kindly suggest if there is anything I need to import to the project, thanks a lot for your effort!
