[copper storm]

do you solve it already ? does it required vuforia ?

[glossy abyss]

I am working on an AR project where you can scan multiple images. And prefabs appear on each image. Now I want the spawned prefab to be destroyed when the image tracking is lost. Can anyone help me out with this piece of code?

[hybrid perch]

Are you using AR Foundation? The TrackingState is what you want https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@4.2/manual/tracked-image-manager.html#tracking-state

[glossy abyss]

yes I am using AR Foundation. I have an ARTrackedImageManager script on it which spawns the prefabs when tracking is found

[hybrid perch]

Or actually might be the ARTrackedImageManager event that's best https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@4.2/manual/tracked-image-manager.html#responding-to-detected-images

The code snippet there is what you want

[glossy abyss]

'''

I know it's a bit cheap to place the whole script here. But I am really struggling in finding where to place the code

I think it is just a few lines of code for it to work. But can't seem to get my head around it.

[hybrid perch]

This is the internal ARFoundation script, not your own?

You're not supposed to modify this

[glossy abyss]

no indeed this is the internal script. Do I need to add an additional script to it?

[hybrid perch]

Yes you need to make your own script and attach it to the manager

[hybrid perch]

You can literally just copy the code from this snipped

[glossy abyss]

you mean this part?

'''[SerializeField]
ARTrackedImageManager m_TrackedImageManager;

void OnEnable() => m_TrackedImageManager.trackedImagesChanged += OnChanged;

void OnDisable() => m_TrackedImageManager.trackedImagesChanged -= OnChanged;

void OnChanged(ARTrackedImagesChangedEventArgs eventArgs)
{
foreach (var newImage in eventArgs.added)
{
// Handle added event
}

foreach (var updatedImage in eventArgs.updated)
{
    // Handle updated event
}

foreach (var removedImage in eventArgs.removed)
{
    // Handle removed event
}

}
'''

[hybrid perch]

Yes

But there are different ways to do this, can you describe again what you want?

[glossy abyss]

sure.

so I have multiple images trackers. If I scan an image a predefined prefab should spawn on top of it. But since there are multiple images I have laying on my table not all of them are within the camera feed and they will start floating when out of frame. To avoid this I would like to destroy the spawned prefabs that are not tracked anymore.

[hybrid perch]

Can you share the prefab image pair manager script on https://hatebin.com/

[glossy abyss]

sure
https://hatebin.com/bschygqdqn

[hybrid perch]

You already have all the pieces you need to do this pretty easily

[glossy abyss]

i am really curious

if you can lead me in the right direction or maybe help me learn it

I think it is somewhere in here? void OnTrackedImagesChanged(ARTrackedImagesChangedEventArgs eventArgs)

[hybrid perch]

Yes

After the first foreach loop, add anothes one

foreach (var removedImage in eventArgs.removed)
{
  // if we are detecting that an image was removed, check if there is an entry for this image GUID in the instantiated objects list
  if(m_Instantiated.ContainsKey(trackedImage.referenceImage.guid))
    {
    // if there is a match then destroy this object
      Destroy(m_Instantiated[trackedImage.referenceImage.guid]);
      m_Instantiated.Remove(trackedImage.referenceImage.guid);
    }
}

[glossy abyss]

I get this error in my code

should I replace "trackedImage" with "removedImage" ?

[hybrid perch]

Yes, that's my bad

[glossy abyss]

alright man. going to test it out now.

😦 hmm it is not working

the objects stays on the screen

[hybrid perch]

You might need top check for runtime errors then

[glossy abyss]

thanks man!

got it working

[hybrid perch]

[placid glacier]

Hey, I want to make automatic placement for my character in AR, but it's almost never placed at the floor level

Do I have to wait for multiple planes to be detected and then chose the one with lowest height?

I've tried simply doing y=0 and having Tracking Origin to floor, but it doesn't work

I'm also currently spawning as soon as the app detects any plane and quite possibly it's at wrong height, but how do I set this up properly

is Tracking Origin also based on lowest currently detected plane?

[rancid epoch]

yoo gabriel sorry for out of topic

but do you ever doing gaze interaction from your AR camera ? to trigger some object ?

[hybrid perch]

AR Foundation has no concept of what a floor is, only anonymous horizontal planes. You can make some assumptions, like the app being opened at roughly 1 meter above the floor, but nothing is definite. I think if I was gonna do this I would define the biggest detected plane as the floor

[placid glacier]

Thanks. I'm gonna go with both ideas, find the biggest planes and compare height

[placid glacier]

Sorry didn't see this because you tagged Ole, but yeah, super simple, just raycast from touch position or screen center, get the object from hit.colliders and send message or get component directly

[rancid epoch]

hold on I'm gonna straight forward

https://www.youtube.com/watch?v=OE66gtiF8QQ&pp=ygUWZ2F6ZSBpbnRlcmFjdGlvbiB1bml0eQ%3D%3D

I just follow this gaze interaction to a cube from scratch

I just did what he taught, exactly 100%

I don't have error message, but pity it failed

may I send you the package I've made ?

[placid glacier]

yeah, I feel like this is done exactly how I wrote. If you follow a tutorial and do it 100% the same, check versions of ARFoundation

the API might have changed and you are using 2 year old methods to do something and it's not working

the video is from 2020

[placid glacier]

I won't have time to check this, but if you can paste the code that does the raycasting I'm sure someone here will be able to help

[rancid epoch]

sure I'll do

[placid glacier]

but tbh, this has nothing to do with AR at all, it's just raycasting, and calling a method from the hit object

[rancid epoch]

but seems he didn't add some raycast component on the AR camera

[placid glacier]

it's what you do everywhere, in FPS games for example if you shoot a character to take his hp

[rancid epoch]

are you sure ?, coz my other plug in like mouse interaction, didn't work on AR scene

[placid glacier]

do you have a mouse plugged to your phone? 🙂

check for touch and not mouse input

[rancid epoch]

mouse interaction (cursor clicking interaction)

[placid glacier]

or just do it in Update so it raycasts continously

I've quickly checked the video and yeah, this is everything you need

[rancid epoch]

I wrote them all

[placid glacier]

and obvously, the "InfoBehavior" component on the object you want to use

then it should work, can't help you more, you literally have the exact code to do this, and it has nothing to do with AR

go again from start to finish and check if you're missing something

[rancid epoch]

ok let me double check

[rancid epoch]

um does unity version matter in this case ?
the videos using 2019.3.4f1 and currently I'm with 2019.4.4f1

[placid glacier]

no, it doesn't matter

[rancid epoch]

if anyone willing to give an attempt for this 🙏 I really appreciate it

https://github.com/Third-Aurora/ARFoundation-Basic-Example and this is the AR template for 2019.3.4f1

Hi there, I need some help in related to gltf importer for unity.
Can anyone please suggest the most suitable pluging available?

I have tried piglet, siccity's GLTFUtility, and UniGLTF.

But with each I faced some issues with quality.

Is there any other option that can maintain the quality after import?

[finite cloak]

Hi, i need some help here with ar foundation & ar core, i got the basics setup and got my camera feed working once i build up my app. However i can't seem to add ui elements and for some reason the renderer can't be set to balanced which i had before

[finite cloak]

help???

[nimble fossil]

You are mixiong up the URP setting and the Quality setting pipeline asset

Anyone know why ARTrackedObjectManager is not instantiating the prefab?

[finite cloak]

what

[nimble fossil]

yes

[finite cloak]

i don't understand, i would like to fix both problems

[rancid flame]

"Hi there, I need some help in related to gltf importer for unity.

Hi there everyone, Can anybody please help me with this issue?

[nimble fossil]

Are you sure its the importer, that is the problem or your mesh probably? What Problems do you have?

[nimble fossil]

The balanced version of the pipeline is not being selected in the render pipeline settings, its in quality afaik

[rancid flame]

Hey @nimble fossil Thanks a lot for replying.

So the recent update I figured out with the mesh in case of siccity's GLTF utilty importer that it doesn't cull off automatically for which I checked the shader graph setting "two sided" and resolved the issue.

Other issue with the same importer was reversed normal as one the sub-component of the model was mirrored in blender, I made the normals reversed for that particular sub-component via script in unity itself and it fixed the normal as expected, also decided to fix this in blender itself.

The thing is I don't have these issue with piglet importer somehow it manages these issues automatically.

The only issue with piglet is when it imports it creates a prefab of it which I don't want where as Siccity's GLTFUtility makes the gltf/glb file readable in unity after import which is much suitable way I think.

[nimble fossil]

But whats the issue with having a prefab, which is basically holding the source file?

[rancid flame]

1. It (Piglet) takes a lot of time for importing compared to siccity's GLTFUtility.
2. Managing the main glb/gltf file along with the prefab is difficult as if I switch the git granch and come back to the same branch again it imports and creates the prefab again which I want to avoid. @nimble fossil

[pale musk]

Can anyone help me how to download more than one model that I have uploaded to firebase storage or google drive? I can get individual models from google drive, but I need to get all the models in that folder and I have no idea how the job will be. Please help... Other platforms are also possible, these are not necessary.

[rich finch]

Anyone knows if the cloud anchor only works to save something on a fixed location or its possible to change its location while anchored? And someone with other phone see it moving or see it at the new location sorry about the weird english

[midnight narwhal]

Hi! does anyone know if MRTK 3 supports Azure Object Anchors? or is that only for MRTK 2

[rancid flame]

Hi @midnight narwhal I am not sure, I have only tried it with MRTK2.

[vital bronze]

Do you want make multi player experience in AR?

[rich finch]

Yeah, something like that

It would be something like, imagine some kids on a school, then they would use the application on the same room/place, and build something together on different smartphones

[rich finch]

If anyone has ideas of how i could make it with ARCore, tell me, please

[warm abyss]

I think lightship ardk has a framework for it, but that's when just using their tools.
Otherwise netcode for gameobjects might work

[rich finch]

Lightship seems interesting

[warm abyss]

It is, it's my preferred sdk for AR games.
Their new beta even integrated with AR Foundation, so that's the best of both worlds

[rich finch]

Interesting

Hard part will be have to learn other thing for the 3rd time lol

But its life

[warm abyss]

You could ask in their discord how the multiplayer of 3.0 beta works. Since they use AR Foundation as a basis in that version it might be relatively easy?
But multiplayer is complex no matter the solution you use

[rich finch]

Yeah

Im kinda new at programming

Im part of a project with a group

Its something very advanced for me yet, but im trying

With anchor, i was using their sample and modifying it

[rancid flame]

Hi everyone, I am using Unity 2021 LTS.
Can anyone suggest a plugin for prefab replacement that keeps the nested objects as reference in the project.

Just like how "prefab replace" feature of 2022 LTS works.

PLEASE HELP!!!!!!

[distant axle]

https://www.youtube.com/watch?v=WOJzHz4sRyU&t=68s things like this ?

[rancid flame]

Yes, basically I want to keep the link of references (including it's nested objects at least for the case if mesh name and hierarchy isn't changed) of old prefabs's instance intact over the project when prefab is replaced.

[barren mirage]

I am using Unity 2022.3.4, and AR foundation 5.06 with ARCore. For some reason my camera is black when I run this on my phone, this is despite me having AR Background Renderer Feature added on my render asset and ARCore enabled in the XR settings. Does anyone one know what's happening? (the AR functions correctly, it just not rendering the camera)

[distant axle]

do you ever tried lower version with same projects ?
what is AR BG renderer worth for ?

[slim zodiac]

Hey, does anyone know how to change the icon of a MRTK button via script?
I set the icon via ButtonConfigHelper & would like to change it when it is clicked. I don't understand how to access it.

[vital bronze]

Netcode for the multiplayer functionality and explore the AR core cloud anchors for making shared experiences

[placid glacier]

Hey, is it possible to somehow detect events like blinked, mouth open in ARFoundation face tracking?

[placid glacier]

I've found this https://docs.unity.cn/Packages/com.unity.mars-ar-foundation-providers@1.5/api/Unity.MARS.Data.ARFoundation.html
but it's Mars, so I need a separate licence to use this APIs ?

[timid kindle]

Hello nice people of Unity community.
I'm an experienced Unity developer but first time diving into AR. I am able to make an empty AR scene with a cube in it and run it on iPad. That part is easy enough.
The first requirement I need to deal with is... Detecting QR Code images from the real world (also reading their code and position/orientation). These QR codes will be used as anchors.

I have done quite amount of Googling on "QR Code in AR Foundation" but interestingly I can't find anything usefull. Sure, some results come up but they involve using 3rd parties like ZXing and such. Doesn't Unity's own AR "Foundation" have any QR code functionality?

If not, what is the most modern/up-to-date way of dealing with QR codes in AR environment?

Thanks.

[warm abyss]

Ar foundation and ARCore/ARKit in general don't support QR codes.
You say you want to use it in anchors. If that's it you could also use image detection to get these anchors.

Maybe vuforia supports QR?
Otherwise look for a library to take in the camera feed and get QR codes out of it

[timid kindle]

It's very interesting that base AR libraries (iOS, Android and Unity) don't provide support for something very common and simpler than image detection. Thanks for the info. I'll give ZXing a try then.

[warm abyss]

Not necessarily simpler than image detection. Different goals and different applications usually

[glossy flare]

Hello, you can use this Assets:

https://assetstore.unity.com/packages/tools/input-management/qr-foundation-174020

Or build yout Own system using ZXing

how does he has those awesome reflections on the model in an AR app

[wary elk]

Like I tried to use HDRP template but it's isn't supported for Android and IIOs

[frail totem]

hello,

i built an AR Projekt using WebGL.
iOS everything is okay. Android mostly. But on some Devices i have a black screen. I don't see a camera feed nor the Szene. If i present the marker, i hear the audio. So the tracking works and the scene seems to load korrektly. But i just have got a black screen. Not on every Android Device 😦 Some are running fine.

What can i do?? 😦

[scenic wyvern]

what's a good cheap phone for AR development?

I've got my eyes on the "Samsung Galaxy A53 5G". Does anyone here use that?

[wanton turtle]

That would work. My goto for low cost is Pixel 2's as they run about 100 bucks. The A53 has more punch and you'll get more out of it. Personally, I use an S22 ultra I think but haven't gone to the 23 (yet). Migrating phones is a pain 😄

[scenic wyvern]

thanks 🫡

[wanton turtle]

I'd recommend looking into the third party plugin you used. AFAIK, WebGL based AR isn't natively supported in Unity. Outside of Unity, I tried about a dozen frameworks with varying success. Not sure what you used to assemble it though or if WebGL AR support was natively added at some point.

[wanton turtle]

https://m.youtube.com/watch?v=lVctb8s_OCc

It's all built into ARFoundation and ARKit already

Interestingly the lighting inside the car isn't very accurate. So I'm not sure he had the lighting setup properly

[vital sage]

hey I'm having the same problem but i'm not being able to find a solution. Anyone knows how to fix this issue?

[wanton turtle]

Unity doesn't support AR on WebGL, AFAIK.

[vital sage]

Oh okay thanks! and in native android apps? I keep having the black screen issue when I open the apk

[wanton turtle]

Hmm, if you can, I'd check the camera permissions - and then check the Unity log on the device

[vital sage]

This is with camera’s permission on

Camera not displaying image but the digital assets

[placid glacier]

How can I find some information on how XR Simulation works - I have it enabled, but in my image tracking scene this currently detects first image from reference library, without any tracking image in scene physically. Can I use it to somehow emulate scanning in editor? So that I can place tracker image (as a sprite, mesh with traacker material etc), and "scan" it with simulator to spawn object?

[placid glacier]

Another question, how do I place prefabs in image tracking, I've noticed that the rotation is always off. If I open the app looking 90 degrees left from the tracker, then point at it, the content placed will have different rotation if I opened the app looking straight at the tracker

I always spawn the prefab at 0,0,0 position and rotation

I tried parenting it to found tracker, and then resetting transform, but it does the same thing

[fickle maple]

I am buidling an android Vuforia app but am getting this error on building.

this is the log file.

[timid kindle]

Yes. This is what I ended up with. Thank you.

[cunning plank]

Hello, I’m new to AR but did a simple iOS app yesterday, looking for a tutorial on tracking 4 points or markers to then draw a plane across them, for such as a tv that would have dynamic changing images

[cunning plank]

I think you have to set rotation in the actual prefab object editor itself?

[heavy tundra]

Hey I'm having trouble placing a sphere rigidbody on a flat surface on an AR foundation scene, I'm thinking it's because when the flat surface is placed, ar foundation updates its rotation? Any help would be appriciated!

Thank you!

[barren mirage]

So I noticed that in AR Foundation, any object in the scene will appear and I can change their position (For example, I can move it to where a raycast hit on a surface), but you can also add an anchor component to objects too... What does that do exactly that it's isn't already doing by itself? Is it just giving it more secure tracking?

[warm abyss]

An anchor is a defined position in the 'real' world, and should not move. When it's off screen it should keep steady and when on screen again it should reconfigure.
An object is placed in the world, but might not have the same persistance as an anchor.

For many AR games it doesn't matter that much. But for example with the vision pro you can have anchors which will stay even when an app closes and reopens

This is my understanding of it
@barren mirage does that help?

[balmy basalt]

how's it ended mate ? ever tried the one from the store ?

[true stag]

is this an appropriate channel for that? Also the link took a long time to load and made me nervous that it redirected to a very long link at a different site.

[fossil flower]

@mellow sinew There's no advertizement here.

[tawny warren]

Hello @everyone , does there anyone here working on Microsoft HoloLens? I have made a test app using Unity and the functions and the objects are all good when I test it in Unity, but when I test it them in HoloLens, the objects are not showing at all as there is no any objects there, do you know why this is happening and how can I fix it? it is very urgent and thank you in Advance

[hybrid perch]

You might not be running the correct scene? Check the build settings

[true stag]

I don't believe this is inside of the arfoundation package, but if you look up "cloud anchors" or "persistent anchors" I believe the individual platforms have their own current solutions, in case that helps.

This feels like a verbose article but it does seem to have the details you would need in them https://www.google.com/amp/s/skarredghost.com/2022/01/05/how-to-oculus-spatial-anchors-unity-2/amp/

Hey I am using snapdragon services to create an AR app on the thinkreality A3, what is a good way I can record ar footage of the build, it is built to an android.

I cant seem to find much online.

[warm abyss]

Android has screen recorders. XRecord is the one I use

[acoustic iron]

This will work to record the footage in the AR glasses?

[warm abyss]

No clue, but doubt it. I suggest checking if the sdk has some kind of recorder?

[acoustic iron]

it does, it sucks.

how to render shadows in Unity with ARcore

https://assetstore.unity.com/packages/vfx/shaders/shadow-receiver-urp-ar-228069
https://assetstore.unity.com/packages/vfx/shaders/shadow-receiver-urp-free-228074

[wary elk]

Hey thanks for this i tried but it ain't working I am using Unity URP in 2022.3.4 and AR foundation

[warm abyss]

What doesn't work?
2022 is supported.
Did you check the docs and add the shadow receiver material to the AR plane?

[wary elk]

the shadows they ain't showin up with my model , I haven't read the docs I'll read them

[warm abyss]

Enable transparent receive shadows, make sure shadows casting is enabled and has a decent size (for the quality tiet active on the phone, not just the editor!), And make sure there is a plane with the shader and a directional light.
Then it should work. Haven't seen any issues in 2022 myself

And make sure the mesh renderer actually casts shadows

[wary elk]

oh alright mate , I'll try with this thanks for the help

[wary elk]

I imported the package > made a mat and set it to Shadow reciever URP / shadowTransperent > Applied to the AR plane > and set that AR plane in Plane manager

[warm abyss]

Does the demo scene show any shadows?

[wary elk]

yes

[wary elk]

i am trying to make a 3d plane the child of the car and remove that AR plane on plane managER

[warm abyss]

Can you send a screenshot of the AR plane?
And maybe try with an unlit plane first to see if the plane does spawn properly?

[wary elk]

Okay sure

[warm abyss]

And check if there is just 1 active quality tier. Often there are multiple and the one used on mobile builds has lower quality without shadows

[wary elk]

I tried that plane thing I mentioned earlier and it's looking better

[sinful wind]

Hi guys, any one can help me on how to fix compiler errors when entering play mode. I started today with AR pathway on unity learning and experienced this , I checked every step from beginning if i made a mistake at any step but i am not able to figure it out. Thank you.

the issue

[balmy basalt]

could you copy paste and dm me the error ?

[sinful wind]

i managed to find the issue , in the project manager the AR Foundation package was the problem, it was updated to 5.0.7 , i removed that and reinstalled the 4.2.8 version, which just removed all compile errors and now i can enter into play mode, with no more errors.

[sinful wind]

thank you , i managed to solve it 🙂

[balmy basalt]

what are you trying to make ?
will there any tap feature on it ?
(when player tap on the smarthphone screen, it triggered some UI canvas)

[sinful wind]

been stuck on it googling for a while , and suddenly it struck me to check packages versions

[sinful wind]

at this moment i am learning how to create AR app, I want to create a wall decor app because i make art using light spectrum and i think it would be a cool idea if people can just scan thier empty walls and see if my art will look good on their wall or not?

[balmy basalt]

ohh that would be great

but what if you have several design to implement ?

[sinful wind]

The idea is first step is to get one image, but then later may be add a scroll effect to images so they can toggle between images and decide which one fits the best to their decor.

like a side ways navigation icons left and right < image > which can be touch interacted , i have no clue at this moment but will eventually get there.

[balmy basalt]

not trying to bring you down, but as far as I know, you can't use a Canvas UI for AR project

[sinful wind]

i just started learning unity pathway for AR today, so i am sure i can in future find a solution, at this time i dont even have a clue about the problem that you are suggesting - what it means or what is its implications or what exactly is using a canvas UI for AR project is .. but i am confident i will progress over time .. its a challenge i have to take to stand out of the crowd.🙂

[balmy basalt]

just ping me for any question, I'm practicing too rn

[sinful wind]

QUESTION : If someone can help me understand for AR Foundation if asset "reference image library" for marker based AR app is same as creating a database using vuforia engine ?

[fossil flower]

@sinful wind Don't tag people not in conversation with you into your questions

[vernal bison]

Hi, Anyone work with Passthrough API to see some specific real object?

[gaunt prism]

I made a custom script for AR Foundation Image Tracking, but it has problems to show the panel and hide the scanned image information panel, so when the images are not tracking they become limited but cannot track again like normal this happens when I slide the image on a laptop, if the camera is removed from the image first it can only be like normal.

foreach (ARTrackedImage trackedImage in eventArgs.updated)
{
    string imageName = trackedImage.referenceImage.name;
    bool isTracked = trackedImage.trackingState == TrackingState.Tracking ?? false;
    Debug.Log("Batas");
    Debug.Log("Tracked: " + trackedImage.trackingState);
    Debug.Log(imageName);
    Debug.Log(isTracked);
    Debug.Log("Batas");

    if (!_instantiatedPrefabs.ContainsKey(imageName))
    {
        UpdatePrefab(trackedImage);
    }

    RemoveCurrentPrefab(imageName);
    ChangeStatus(imageName, isTracked);
}

[cedar spade]

any AR devs in here who work at Unity?

[delicate aurora]

hello, i have a question. is it possible to combine 2 methods? so i want to show a 3d stage using image tracking but the problem is that user need to be close to the printed marker to be able to see the 3d stage. So i have a plan what if we just need to get the position,rotation of the marker then use hit&test method to place the 3d stage, is it possible?

[warm abyss]

You are in the ar channel in the unity discord, yes there are
Just ask the question

[warm abyss]

Sounds fine. You can also set an ar acnhor when the image is detected and use that for the tracking of the stage

[delicate aurora]

i see thanks, so the problem i have now is that the marker is around 35cm on the ground and user need to be able to scan from at lest 1.5m, using image tracking it's not possible user can't scan the marker from that far

probably because the marker is on the ground so it's harder to be recognized

[warm abyss]

Image detection needs to be at least 1/4th if the camera for many devices yeh.
You could fake it that a user has to tap on it and you check the average color around it or something like that

if i wanted to make a AR and VR game. would it be better to work on the same project but in different scenes, or should i just make individual projects for both. Also they would both work the same.

[true stag]

That depends on your controls and ideas, it's absolutely possible to make it for both, as the sample arfoundation project shows, but it depends how your game is set to work out

[wanton turtle]

We have an internal template we use to share the same project on AR/VR, Web Desktop etc. The hardest part was finding a stable unity version that works on all the platforms properly.

So yes, you absolutely can. It isn't always needed though.

It sounds to me like you are probably too far away for hit and test to work either.

But yes, you absolutely can use a marker to get some base transform values and place on hit placement.

[quick zinc]

Yes, I am also looking for that stable version across platforms that works for both PC and Mac.

Which one did you settle on?

[ancient fox]

Has anyone ever had problems creating an AR core project? It crashes at Application.UpdateScene. The dump gave a 0xC0000005 code, accessing an unallocated part of memory most likely but idk what goes wrong tbh. On a fresh install too. Saving has no effect. Your class 'UnityEditor.XR.Simulation.XREnvironmentViewManager' is missing the FilePathAttribute. Use this attribute to specify where to save your ScriptableSingleton. Only call Save() and use this attribute if you want your state to survive between sessions of Unity. UnityEditor.XR.Simulation.XREnvironmentViewManager:OnDisable () (at ./Library/PackageCache/com.unity.xr.arfoundation@5.0.7/Editor/Simulation/XREnvironmentViewManager.cs:169) is what the error is

[true stag]

that's a warning, but not a crash source I believe?

I'm looking for a way to apply textures to ARmeshing with ARFoundation and ARMeshManager, is there way to do this?

Hey everyone, when I do imagetracking and i activate a previously instantiated prefab it gets wrong rotation when the image is tracked correctly :/

[hallow aspen]

Probably a newb question but can anybody help me work out why I can't see any objects in my built game? I placed a default cube in scene and I don't see it plus the objects in the below script don't spawn. I am using 2019.4.4 with a Huawei Mate 20 Pro

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.ARFoundation;
using UnityEngine.EventSystems;


public class Spawn : MonoBehaviour
{
    ARRaycastManager raycastManager;
    List<ARRaycastHit> hits;

    public GameObject spawnObj;

    private void Start()
    {
        raycastManager = GetComponent<ARRaycastManager>();
        hits = new List<ARRaycastHit>();
    }

    private void Update()
    {
        if(Input.touchCount == 0)
            return;

        Touch touch = Input.GetTouch(0);

        if (IsPointerOverUIObject(touch.position))
            return;

        if(raycastManager.Raycast(touch.position, hits))
        {
            Pose pose = hits[0].pose;

            Instantiate(spawnObj, pose.position, pose.rotation);
        }
    }
    bool IsPointerOverUIObject(Vector2 pos)
    {
        if (EventSystem.current == null)
            return false;
        PointerEventData eventDataCurrentPos = new PointerEventData(EventSystem.current);
        eventDataCurrentPos.position = new Vector2(pos.x, pos.y);
        List < RaycastResult> results = new List<RaycastResult>();
        EventSystem.current.RaycastAll(eventDataCurrentPos, results);
        return results.Count > 0;

    }
}

[hybrid perch]

Why are you using that version? 🤔 You should be using the 2019 LTS to avoid possible issues. And you'll probably have to look at the log to see if you have any errors

[true stag]

Well, I know that if you place a default cube at the origin, it will actually spawn over your current position when you start the AR app, so you'll have to move backwards to see the cube since it's large and your camera is inside of it

[pale musk]

How can I replace the Duplicate Stage object defined in the Content Positioning Behavior script in the plane finder in the Vuforia library with code?

It's from this tutorial.

[warm abyss]

Check logs

[glossy abyss]

I'm wondering if what I am doing is the correct way to approach this. So I am working on an AR app where you scan an Image and then a Prefab instantiates in the scene. Different Images with different Prefabs. There is a canvas in the scene with questions on it. Every image has it's own Quiz questions. Now to know for the "Game Manager" script which questions should be visible on the screen I do it like this: There is an Update function that FindsObject by Name in the scene. If it is found then the corresponding questions will be shown. Also there is a Null Check. So if the object is found it stops looking for it.

Is this how I should approach it?

[pseudo garnet]

Hallo everyone, does anyone knows this error: InvalidOperationException: Failed to load XRReferenceImageLibrary 'ReferenceImageLibrary': library does not contain any ARCore data.

[wanton turtle]

I wouldn't do it this way, FindObject is a slow system. I'd probably track when they are instantiated and destroyed in a list, if I needed access to them. I'd probably use Events and Delegates to communicate between all the parts.

But, from what you are doing, it doesn't sound like you need to care if the user found a code and generated an AR item. You may want to track responses, but that's easy enough when they submit their result. Anyway, without knowing more, it does sound like a less than ideal approach - but hey if it works, and performs well, I'd also say stick with it

[wanton turtle]

It says the image library is empty or missing on Android

Also, make sure you don't have two reference libraries. ARFoundation isn't well tested for real scenarios, IMHO. But if you have more than one library, it will break on mobile and unpredictably pick only one to compile.

[wanton turtle]

Could be the graphics settings or something. But there are logs on mobile you can see at runtime (android logcat for example) to debug better

[half basin]

My phone isn't surprised by Google AR.

That's why I can't compile.

[wanton turtle]

You can set it to optional for unsupported devices. It's one of the big downsides to using arfoundation, as it really only supports a subset of devices through arcore/kit.

[swift bronze]

Hello , Does anyone know how I can extend support for app built with ARFoundation (ARCore)? Like pokemon go does maybe?

[tiny plover]

Hi, every time I create an AR project, unity crashes. Just wondering if anybody has any idea of a way to fix this? (Ping replies)

Hello, is there a way to hide a GameObject that is being blocked by a real-life wall

I have try occlusion culling but it isn't working

[wintry ledge]

anyone knows how to fix this problem?

[true stag]

That looks like your background color might not be set properly, or isn't being set

[warm abyss]

Ar foundation can use depth to do depth occlusion

[dreamy pond]

check clear flag in your camera. maybe you are set it to don't clear.

[empty rapids]

hello everyone, i have build an simple ar application which plays videos on image target using vuforia......but i am facing a problem that when i build the project it is not working on image but when i play without build it is playing..so whats the issue??

[cunning nexus]

The image is not clear/trackable because of a wrong setup in vuforia potentially, or your device doesnt support ar?

I also have a question with image tracking(AR foundation), I want to open a UI popup when an image is added/first tracked, when the popup is closed I want to rescan the image and be able to open the same popup, but the image always stays in the tracked list and there is no remove functionality so I cant open the popup a second time, any ways around this?

[empty rapids]

but then why it is tracking in my pc wheni play it as in theviewport play button....and i am not os good with unity and coding. so i guess u can detect the trackable image and once agin open the ui, means here is the video may be it will help u

https://www.youtube.com/watch?v=cWEhMlN_bSk

[cunning nexus]

If you are using the simulation vuforia has inside of the editor that doesn't really take in consideration tracking, in the simulated environment its always going to track the image even if the quality of the image etc is really bad, the only way to truly know if it will be tracked in a real environment is using it on a device if that makes sense

[empty rapids]

ya i guess, so any ways to fix it like i didn't know where to start...

[cunning nexus]

is the stars quality bad in vuforia? it should show stars from 0 to 5

if its 0 then maybe hte image is just hard to track in a real environment

[empty rapids]

3 stars ..

[true stag]

I'm not sure if there's any easy code to do this, you might need to refactor your idea and make it spawn a button/surface to simply touch it and bring up the popup?

But I'd be happy to be proven wrong if there's an easy way to do that

[cunning nexus]

thanks for the suggestion hoka i used your advice a bit, instead of a pop up i have a UI that updates everytime a new image is scanned with a constant button that the user can touch to view the details.
Thought turns out the popup is also possible just in a slightly weird way, by checking on "trackedImagesChanged" event and instead of checking on added you check on updated images and see if their state is "tracking", once it founds one it opens the popup and a simple bool locks the tracking until the popup is closed again

thanks again!

[true stag]

I'm glad you found a solution that works for you!

[round vale]

I've been having the same kind of issue, I would like to have a button to stop the tracking of an object and remove every GameObject that I spawn after detecting something with no success. Seems like destroying the GameObject present in trackables leads to my app crashing. I'm currently trying to make it work with an ARSession.Reset() (that I tried to avoid because it lags out the camera feed) but it ALSO crashed my app for some reasons 🤔 . As I'm not experimented with Unity I'm wondering if that can be because of a memory leak caused by one of my gameobject (that will be destroyed) being a VideoPlayer taking a video from an URL ?

Can I post my logs here ?

[empty rapids]

hello there...why i am having an error saying object reference not set to instance of object while i am running an ar project that i have created from this video https://www.youtube.com/watch?v=Hjx9o8D1DZg&list=PLSc07dYXbtBmf2iF6GeWV_lvHaqLMJWdp&index=5 and fere is my console error

@fervent lake what are you using for AR? ARFoundation doesn't support WebGL - there are a few odd tools like Zapier and stuff, but more details would defintiely help

Hello everyone, does anyone know if there's a way to make AR Core work on an unsupported device?
I have an OPPO A96, but on AR Core's list of supported devices, the supported one is OPPO A96 5G (from what I've seen, mine is probably not the 5G variant). Google play tells me that google play services for ar is not supported on my device, so I downloaded it as an apk from the "ARCore SDK for Android" github. When I run my test app, I'm debugging ARSession.state and it gets to ARSessionState.SessionInitializing. Could it be that Unity thinks that AR Core is supported because I have the services for AR apk installed, but can't get to ARSessionState.SessionTracking because in reality, AR Core is not supported?

[empty rapids]

okk

i have checked that

and it is solved

You can force install it, but you can't make it actually do anything

Maybe look for smaller tutorials

Start with pinching, then couple that to scale

Then look for how to detect dragging, then couple that with rotations

[tame leaf]

Hello, for a project I’m working on I need to track the position of a real life object and have an asset mirror the position of the real life object in real time. The idea is to have a stationary camera connected to the PC which will get the live feed of real life object’s position. I’ve been looking into Unity’s AR Foundations to achieve this but I haven’t gotten anywhere yet. I’m new to Unity and I was wondering if I’m on the correct path and what I would need to do or if this is something that has been done before and I can get a bit of guidance (from what I’ve gathered, I can’t find any similar projects on the internet)

[wanton turtle]

I would use OpenCV

Rather, I have used OpenCV with the Quest 1 to create real world spatial tracking for a warehouse scale VR game. Not sure most AR frameworks don't work well with moving targets. You may need to spend a day testing different frameworks and solutions

I am not getting Meta Passthrough API for Oculus SDK v56 to work in Unity 2021.3.8. I have enabled all the relevant switches based on the top results and the Oculus pages on Passthrough API. I'm stuck in a corner with this error:

Warning-XR Device was switched during runtime with overlays still enabled. When doing so, all overlays constructed with the previous XR device must first be disabled.
UnityEngine.Debug:LogError (object)
OVROverlay:LateUpdate () (at Assets/Oculus/VR/Scripts/OVROverlay.cs:1199)

I can safely say that I don't know what an XR device is in this context and why it would show up as switched. I'll begin by inspecting that line of code.

[half basin]

Anyone?

[wanton turtle]

@half basin Very few people have used the pass-through specifically on an oculus - the chances of one of them having your issue is extremely slim. I'd say, what is the error telling you? Do the demos do the same thing? Sounds like the XR device (headset) is being detected as changed (turning on or off a new headset after the API is initiated) and to disable the overlays. But that's just what the message is telling you. I'm not sure what else there is to say on it

[half basin]

True, it's kinda like a dog whistle.
Now the main issue is I have enabled practically all the switches needed. Something is amiss. I have followed all the tutorials, including the ones used to set up working examples.

[wanton turtle]

Well, I suppose that'll teach me a lesson for replying. Good luck on the digging.

[half basin]

Do you want me to continue posting here if I find anything?

[slow portal]

Helo all, i am not too experienced. My end goal is to have a image and when the camera is shown at it is to show a prefab. preferably using ARKit to use on iOS. i have no problem installing the app on my phone and the camera appers. i have tested and having a cub will show on the camera in the "AR World". i have attched my script below. The image to track and prefab have the same name, the script is on the "AR Session Origin"
for some reason the image is not tracking. is there any way to test it in the simulation to see if it is the iOS porting or not

[unreal raft]

How do you what version your EasyAR is in your Unity file?

[warm abyss]

8th wall is amazing and uses WebAR, otherwise Unreal Engine is decent (not as good as Unity I've heard)
Godot sadly has very poor AR support

[rancid kettle]

Thanks 👍 , I've heard great things about 8th Wall too, but the pricing might be a problem for bigger projects.
For what i've seen, Unreal don't have a good AR support either (at least, on mobile, where i'm focusing on).
I'll try on Godot, given the latest updates on Godot XR Tools.

[warm abyss]

The new xr tools mainly work with VR I think.
Godot itself does not support ARcore for example

Mmmmm, ok, thanks for the info 👍

However, I do not see arcoreimg folder. See attached for what I see in my image folder. I thought maybe I could run that line in the tools folder but I just get a "bash: arcoreimg.exe: command not found".

Guys, I am using the arfoundation-samples from github. In SimpleAR (uses plane detection and places a GO on tap) I want to place a real life size cricket stadium for which I have set the scale of the model (scale = 140) accordingly in unity and even tried to position the XR origin camera and the model prefab but the stadium is still showing at a fixed location after everything. What do i do?
(Previously when I tried with a room size model of a room then that worked perfectly (Scale was set to 1).

[warm abyss]

Check if all gameobjects and children of the prefabs are at origin (0,0,0).
If so, debug log the placement position and log the prefab position when it spawns (in Start)

[fickle maple]

Yes.
Ok. What's the difference?

[warm abyss]

Then you can confirm which one reports a wrong value. If you set a GO to the world position they should be the same'

[fickle maple]

i dont understand. What two things are we talking about here>

[warm abyss]

The place you are trying to spawn the object and the object you are trying to spawn

[fickle maple]

ohk. Let me see.

Hi. I've started playing with AR, and playing with rear camera is fine, but when I want to switch to the front camera I have a black screen. What I've read in order to switch to the front camera I need to change "Facing Direction" on "AR Camera Manager" to User. But as I said, I have black screen then. I'm using Xiaomi 11 Lite.

[warm abyss]

I don't think so?

[fickle maple]

Ok

[fickle maple]

Yes u right

[fickle maple]

Well front camera features don't work with ar core ig. Use iOS ar kit.

[fickle maple]

Both the pos are same and the stadium is just above me in some form

[fickle maple]

@warm abyss all working now. Just that my stadium is moving when i am moving. This should not happen. How do i fix it?

[warm abyss]

Depends on your setup

[fickle maple]

everything is same as in samples

i just changed the prefab to instantiate

[warm abyss]

If its exactly the same with a model swap and it does something else, its not exactly the same

[fickle maple]

Well i have disabled the arplane man, ar raycast man, plane visualiser after the prefab is placed. Is it cuz of that?

Hi,i am trying to turn on the Ar on my game but when i build the game and i try to activate it it doesn't work (and i don't know why),in your opinion what i am doing wrong?

i know there is an error in the script,in the build there wasn't

[cold dawn]

I implemented also an UI on my oculus standalone to see what happen when i try to call the function to activate the Ar called "AttivaRealtaAumentata" that you can see in the photo,but nothing happens

Can you please help me?

Hi All, I been deving AR application for a couple of years now. I have spent many hours now trying to update my AR game from version 2021 to unity version 2022.3. Each time the same bug persists. Everything works fine, but when building an apk to android and running, the screen remains black with no unity logo appearing or anything rendering, I have to minimize the app then open it again to make my scene appear.

I've seen people post the same issue with no fix. https://stackoverflow.com/questions/76410780/unity-android-app-black-screen-on-startup

This is quite a frustrating issue, and it seems like there's a problem with version 2022.3 and ARFoundation as I've tried this multiple times with a blank AR template project as well. Has anyone else been experiencing this issue with 2022.3 as well?

[warm abyss]

I've not experienced this myself. Make sure unity and all packages are up to date and maybe delete the library folder to remove any old caches.

Also check logcat for any errors

[topaz solstice]

Hey, is there anyone here with experience in Google Geospatial Creator? I'm working on a project and am having issue in object placement with reference to height.
Can anyone please help me with this??

[undone ember]

Thanks for the response, I've tried the solutions you've suggested, unfortunately with no success. I'm starting to think maybe it's the Android device I'm using. Upon further inspection from logcat, it seems like the state the application starts in when opening is an incorrect state.

hi, im brand new to XR development and ive come to a problem.
im trying to do passthrough with unity and launching it is fine but the frame rate is like 2 fps. Im using quest 3 through air-line and this is my pc specs:
CPU: i5-9600K 3.70GHz
64 gigs of RAM
GPU: NVIDIA RTX 3070

Traditional vr works fine however, just want to get passthrough working, thanks

[bitter star]

Someone ever used vuforia here?

I need some help 🙏

I wanna use it for indoor navigation

[warm abyss]

Just ask the question you need anwered

[warm abyss]

Check the profiler and make sure Unity and all the VR tools are updated

[bitter star]

Thats the question

Idk how to use it

[warm abyss]

The check startup guides

I personally use AR foundation or Lightship ARDK
But there are many resources on all bigger frameworks.

This is the same as asking 'I don't know how a car works, teach me how to build one from scratch'.
No one can teach everything, so start learning and ask specific questions

[bitter star]

Ok

[grim dagger]

hello, new to AR in unity. Can you guys help me hide the tracked plane in my AR project? I'd like it hidden but I have no idea yet. How can I hide this yellow tracked plane in placing my game object? Thank you!

[hybrid perch]

Set the alpha of the plane material to 0

[warm sundial]

im using unity 2022.3.11f1 and the oculus utilities plugin is 1.89.0

this is also the first time using the oculus profiler, what else can i do to make it run better?

[warm abyss]

Or remove the material/mesh renderer

[warm abyss]

I've never used that. The Unity profiler can point out where all CPU performance goes and some of the GPU performance.
The tool you have goes more into GPU details of the quest itself, not on PC I think?

[warm sundial]

okey ive never used the unity profiler so i'll search up how to use that

[warm sundial]

here ive done it through the unity profiler

[warm abyss]

If you click on the graph you can see what that frame is doing. Especially in the peaks there are frame dips.

You can also change the info from timeline to hierarchy, sometimes might be useful

[warm sundial]

what do you think i should do?

btw i set up my project the same way this video did (just with newer versions of unity and oculus) https://youtu.be/RpHAZ0N5W1s?si=NYP8axkv8qhCRqZT

[warm abyss]

Drop down the task that takes so long to see what it consists of

The XR Update

Also if it just stutters twice it might be loading something, which might not be an issue
If it does it often it is an issue

[grim dagger]

wow, it worked! Thank you @warm abyss && @hybrid perch !!

[warm abyss]

Ah, gotta love Unity not being specific with this.
But check more of the spikes and try to dig as deep as possible.
I cannot help that much without being in an project

[warm sundial]

thats fair enough, i really appreciate your help

[warm abyss]

You're welcome!

I specialize in performance optimization for (standalone) VR, so if you have any specific questions (or if you want to hire someone for it), feel free to ping me

[warm sundial]

oh cool! i'll be sure to do that ❤️ standalone vr works well with no frame rate issues in this project though, its just passthrough being weird

[swift bronze]

Anyone know if I can do ar placement without plane detection? Is it like regular instatiation?

[warm abyss]

You might be able to use the depth buffer?
Or just instantiate something in the air (relation to camera)

Or make the plane invisible if it's a visual issue

[terse coral]

Hello I just launched in augmented reality on Unity under Vuforia. I have a problem, I can’t find the package that contains User Defined Target. I can’t find it. Can you help me?

[maiden talon]

Does anyone here know about EasyAR? I just joined a project that uses EasyAR but was developed years ago, the system was updated and now there's missing links which I have no idea what are supposed to be because I'm unfamiliar with AR myself.

The attached screenshots is what the scene already had. AR is usable but often breaks / missposition spawned game objects, but an earlier version of the game worked as intended, so I assume it was something that broke on the update.
I'm new to that project but can provide more insight, any help is very welcome.

[outer void]

I've seen Android blackscreen issues reported due to the "AR" feature being selected in Package Manager.

Try deselecting the AR feature (if selected) and re-adding the packages back to your project one by one? We are working on this issue right now.

[outer void]

If you know where you want to place your content, just add an ARAnchor component to a GameObject at that location and parent your content to that.

[outer void]

I've never heard of this issue. Please file a bug using the in-Editor bug reporter (under Help)

[outer void]

Dilmer Vallecios covers this in his Geospatial Creator video

[outer void]

AR Foundation is compatible with XR Interaction Toolkit, but the camera position is controlled by your XROrigin and TrackedPoseDriver components. You cant teleport the camera because we'll just reset the camera position back to its origin-relative position within the same frame.

You should be able to teleport the XR Origin itself though

Hey everyone,
Anyone know any Tools or extensions I can use to test/ Debug my AR project in the editor or another program to help me test my application without building solely to the device?

[outer void]

With AR Foundation 5.0 or newer you can use XR Simulation to run your app in the Editor: https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/manual/xr-simulation/simulation.html

[plush sage]

Hello! I was wondering if there was a straightforward way to get a texture2D of the depthImage via the AROcclusionManager? forgive me if this is a silly question - I'm new ^^;;

[wanton turtle]

EasyAR is pretty broken at the moment, and doesn't have a default called EasyAR_Startup. So not sure what that script is supposed to be.

[maiden talon]

I assume is the standard for 4 years ago when the project was made?

[wanton turtle]

Nope

Depending on the version, it comes with one or two stacks. The more recent one has two. But none has the word Startup in the name.

You can just do a fresh EasyAR project, drag in the same version as the existing app, and see what the default scenes are.

[raw star]

Using the ArSessionOrigin.MakeContentAppearAt() method, I'm placing a prefab infront of the user's android camera. When I'm rotating the camera to look around the prefab stays correctly at the same place but when the user walks around the prefab doesn't stay at its position thus the user can't walk around it or anything since the prefab doesn't stay at the same place.

Any suggestions will be vastly appreciated.

[raw star]

Ι basically want to spanw a gameObject infront of the camera at let's say z = +20 (probably equivelant to meters in real life) that stays there and the user can move and go arround it while it stays positioned at the same place it was originally spawned.

[dark frost]

Hi everyone !
I'm using ARFoundation on Android, but I can't get a light estimation, always returning null.
Any ideas why ?
Most of the topics online are about the ARKit side, but I didn't found anything about Android.

    void FrameChanged(ARCameraFrameEventArgs args)
    {
        Debug.Log(args.lightEstimation);
        Debug.Log(args.lightEstimation.averageBrightness);

        // Modify `light` parameters using ARCameraFrameEventArgs.
        if (args.lightEstimation != null)
        {
            SimulationLight.transform.rotation = Quaternion.Euler(args.lightEstimation.mainLightDirection.Value);
            SimulationLight.intensity = args.lightEstimation.averageBrightness.Value;
            lightText.text = args.lightEstimation.averageBrightness.Value.ToString();
        }
    }

Honestly I'm lost.. It does exist but when I want to use it, it is null..

Has anyone be able to test the quest3 mixed reality scenes included in the oculus sdk?

I dis follow all the steps but it isn't working for me

For example with the ball scene demo

When I build and start it, it ask me if I want to keep the scanned room and if I want to add funitures. So I choose continue. After that a passthrough screen appears with my controller. The screen looks more white like there is filter on it I can throw balls

But the balls don't hit anything from my mesh

They just fall downwards infinite

If I start the game through quest link and just start the scene with the play button in unity, it works

I tried again to create a complete new unity project and followed the steps again as described. Scanned a new room on the quest3, but again I have the same issue

Followed the following documentation: https://developer.oculus.com/documentation/unity/unity-scene-virtual-furniture-sample/

I tried the phanto template, that one works but its older and not a clean setup. Would like to do it correctly

[jade meteor]

Hi everyone new here. Im having a weird issue that i am pretty sure is just something im not seeing. Because it literally used to work just recently but there is something wrong now. So i have This simple scene. Basic multiple image tracking setup

With this tracking script

It used to work fine. But all my recent build it just stopped working. The ar camera turns on just fine. I have another script that loads meshes and materials to some prefabs. And everything is fine

But not matter what i do when i turn the camera to face the image in the reference library nothing happens

This are the prefabs names and some of the names in the library

As long as they match name they work

And is not like my custom script is not working. It just happens recently than on build the AR camera seems to stop working somewhere

[jade meteor]

So after more debugging. What seems to be failing is downloading assets from a server and asigning both mesh and material from there to the prefabs. So this no longer seems to be a AR problem but another altogether

[smoky wyvern]

hi, i want to use ar, face tracking on ios platform. i have a ios build and open xcode 15. my ios device have ios 17. this build is a simple build, i don't wrote any code, just i work on unity editor. my editor version 2022.3.f1. Finally, i get an error this.

"Command PhaseScriptExecution failed with a nonzero exit code"

so I am processing depthimage data as metadata through an NDI. I have reconstructed the DepthImage Texture on the client side, and am looking to feed it into the native shader applied to the ARCameraBackground object as it's _EnvironmentDepth texture, but i'm having difficulties - can anyone provide some assistance or point me in a good direction for this? thank you also, these forums have been incredibly helpful.

[amber python]

What is the best way to blit / access the texture used to render to the main camera in OpenXR?
I'm working on a HoloLens 2 application and want to blit to both eyes using my own texture

[raw star]

I want to do the following :

1. User aims with a crosshair at something specific
2. He presses a button called "Place"
3. A 3D Model/GameObject/Prefab is placed at a specific position for example: (0.0, 0.0, 20.0) so I want the model to appear roughly 20m ahead of the user's position(correct me if I'm wrong on this)
4. I want the model to stay still there so the user can walk around his physical surroundings and the model always stays at its original placed position that was used when he opened the camera and used the button

What is the correct way to instantiate the object ? I tried Make ContentAppearAt() but the object seems to move when the user moves arround the room or whatever outside space. Then I tried Instantiate followed by instantiatedPrefab.AddComponent<ARAnchor>() to see if it makes a difference adding manually an anchor to it. Still the object moves when the user's position deviates from the initial position he placed/instantiated the prefab.

Maybe what I'm trying to do is not possible but really don't know

Hello, Anyone using Two-stage trigger for the meta quest 3 ?
Is it supported jet

[livid coyote]

I am using Unity 2021.3.1f1 and my phone is an Redmi M2101K6G.
I am trying to go through the Mobile AR Development Pathways. I was going through all steps which were listed there to Spawn an Object on an AR Marker. When I came to the point where I had to build and run the system following showed up on my console.

Could someone tell me what the problem might be?

[midnight narwhal]

anyone here familiar with MRTK and QR Code extention from NuGet ? and with the Pose variable ?
I have a unity project where i scan QR Codes, it renders a 3D model on that position, but i want to give it an offset, but every time it changes, or just isnt right. If anyone can help me, please send a DM! :) could use the help

[gritty heron]

For meta quest 3 there are some way to do a dynamic plane detection? I already check new ArFoudnation feature with OpenXr Meta feature but it require the room setup initially.

I try the First Encounter app on Meta Quest 3 and I notice the application could detect plane like table without do the Scene Room setup before the start of application.

Someone have some tips? There is a way to do it custom?

[novel crag]

Is it possible to combine OVR Integration for passthrough capabilities while also using the XR Interaction Toolkit?

[warm abyss]

It might require a custom setup, but it can definitely work

[warm abyss]

https://docs.unity3d.com/Packages/com.unity.xr.meta-openxr@1.0/manual/index.html

It does have plane detection.
How did you set it up?
Do you use the meta openxr AR package?

[novel crag]

thanks @warm abyss

[livid coyote]

I have installed MRTK and am currently using the Hand Interaction examples. However, everything is being displayed in pink. Why is that?

[warm abyss]

You probably use URP
Go to windows - rendering - render pipeline converter
Here select built in to urp, check the materials box, initialize and convert

Has anyone done tracked image in ar foundation?

I did this tutorial https://medium.com/dscvitpune/quick-introduction-to-image-tracking-using-ar-foundation-dea7d2fbdfe9 , and I'm getting nothing.. I'm using Niantic Lightship ARDK but It's paired with AR Foundation , so It has all of ar foundations api and compnents

[warm abyss]

I have in ARDK 2.x, so not AR Foundation

But add logs everywhere you can to see how far it gets, or if it detects the image at all.
Also check the ARCore/ARKit image detection guidelines, as some images work better than others

[swift bronze]

To me it seems that it's not even detecting the image

[swift bronze]

besides I can't reall add logs anywhere because there wasn't any scripting , I did how ever write a script and I did add logs but I get non of the logs

[warm abyss]

Which image do you use?
Tried a different one with more content already?

[swift bronze]

If you seen the tut i posted , and clicked on the Image/video opitions ... I used darth vader

I'll try with serious black like he did in the tutorial

[swift bronze]

I just tried with the serious black image and vid and still nothing

[warm abyss]

Maybe try a different guide?
ARF also has some docs:https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/manual/features/image-tracking.html

It's probably not picking up something.

[swift bronze]

You'll want to upgrade to Lightship 3.0 if you plan to continue to use it by the way , support for Lightship 2.5.2 is ending.

[swift bronze]

I'm in it already

[warm abyss]

Pinged ya

[gritty heron]

Yes it have plane detection but Ar Foundation for oculus doesn't do it dynamically

Room setup
Plane detection on Meta Quest devices requires that you run Room Setup on your Meta Quest device before any planes can be detected.

Unlike other AR platforms, Meta OpenXR does not dynamically discover planes at runtime. Instead, the Unity OpenXR: Meta queries the device's Room Setup data and returns all plane components that are stored in its Scene Model. Some entities in the Scene Model, such as Tables or Couches, include planes, while others do not.

IMPORTANT
If Room Setup is not complete, AR Foundation cannot detect any planes. If your app requires planes, you can use scene capture to prompt the user to complete Room Setup.

[still siren]

how do the xr pipelines render the scene's alpha in HDRP? for example, how is motion blur done?

oh very cool, it work only with OpenXR right? I can't use it with Oculus Integration?

[wanton turtle]

I'll also say these are very reasonably priced options to help them. Love it

[warm abyss]

The shaders are cross compatible. You just have to get a place or mesh that matches the real world, and then you add the shader/material to that mesh.

It's not an example project, but a shader you can use in any project

[haughty tundra]

Hi all! not sure if this is the best channel to ask but:
So I do immersive art installations using portable geodesic domes w/ 360 projection mapping. i'm looking to use VR-style controllers in this space without a headset. i'm looking at valve index controllers or vive controllers, with probably 3-4 trackers. i'm seeing info that I would need some kind of dongle to use any of these without a headset. one person said I would need a separate dongle for every controller and every tracker. the dome is a 30ft diameter.

wondering if anyone has experience with using controllers in this way - what setup would you recommend if you were trying to do something like this?

[warm abyss]

If no one responds maybe try #🥽┃virtual-reality or the forums, since this uses hardware often used for VR

[swift bronze]

I seem to have it working now , I don't know what was wrong

[wanton turtle]

Back in the old days, we had a few of those.

It sounds like it isn't trackers you want (to track any object you stick them on) but vive controllers. In which case you just need base stations and maybe a headset to setup the initial play bounds.

It's ugly and old tech but was reliable enough for us at the time.

Hard to recommend alternatives without more specifics though

I'd start with the basics though - what are they using the controllers for? Because there may be a smarter way without needing any controllers

[haughty tundra]

The main feature I want is point & click I guess.

Ah yeah I said tracker but meant base station

Need multiple buttons.. 1 or 2 joysticks would be nice. VR-style controllers working in the 360 environment is idea(2 point & clicks)

[wanton turtle]

I've used a few other things on a pinch, but the vive controllers may yeah be your best bet... if you were in Calgary, I could lend you the equipment to test it out. We have a bunch in storage (spare parts). The reason I was asking is sometimes a leap motion can be a better fit at individual stations, or a using IR trackers with projection mapping, so you track their position more so than their hands... if you know it's only a few people, a camera or two running OpenCV could work too. But I can see why you settled on vive wands...

I've only done it a few times, and it wss a good 4 or 5 years back. So I'm sure my knowledge would be severely outdated.

I try hard to do things controller free, so we've dabbled a lot with OpenCV, and we even use the kinect for stroke therapy. But it's only really solid if you can invest the time to smooth it out

[haughty tundra]

would the valve index controllers work for this? or just the older vive ones?

[haughty tundra]

I do plan on playing with something like leap motion/connect/opencv in the future

[wanton turtle]

I'm not sure, I never tested those in this kind of scenario...

Vive wands, vive trackers, leap motion, OpenCV, Kinect, Intel Realsense - those are the only ones I can think of that we tested and were successful. We did test things like Myo and such, but I'd just use a camera with hand tracking if thinking of a myo

By the time the index came out, we began being focuses on just VR, and shortly after went entirely wireless headsets for all our clients across the board.

But someone more used to the index might be able to help

[haughty tundra]

Doing a bit of research it looks like they would work the same

[terse coral]

[gusty wedge]

Hey, I've ported a old project I had with unity 5 and vuforia to 2022 with arfoundation (arkit since im targeting ios only).
However I've noticed the camera background stops updating after a while (around 1 minute more or less) and doesn't throw anything in xcode. Also the app works fine, I can just switch scene and it works again...
Any ideas?

[somber olive]

Does anyone know how to get into the closed beta of VisionOS support for Unity?

[still siren]

there is probably an exception. you have to run with xcode attached, and read the console

[cinder birch]

Hello, everyone! I have a question. I'd like to develop a cross-platform AR mobile app (school project) that overlays AR content onto museum exhibits or artifacts. I'm confident that AR Foundation can assist with the core functionality. However, I'm uncertain about the implementation of the content management feature. Specifically, I want the museum administrator to have the capability to independently manage the AR content displayed in the museum. Are there tools or frameworks within Unity that facilitate the realization of this feature? I'm seeking assurance that Unity is a viable platform for implementing such functionality before delving further into AR mobile development.

[wanton turtle]

In our case, we did the Unity application and never heard back. But a while later an Apple rep reached out to us independently about it. I'd go the Apple rep route if you have connections that way

[wanton turtle]

Not really no, there are other frameworks that can kind of do it. Most studios I think have their own framework at this point, I know we have our own small one that let's clients customize their AR/VR stuff a bit. But there isn't really anything built into unity I'm aware of. No idea if you could just buy an asset for it nowadays though.

But, given we are doing it, yes you can definitely build it in quite a few different ways

The important bit is here:
https://forum.unity.com/threads/ar-foundation-add-reference-images-at-runtime-causes-memory-leak-on-ios-but-works-fine-on-android.1271573/

How to update the list at runtime.

We've moved almost all of our basic image marker tracking stuff to webar now though, as it's just a whole lot lighter

[cinder birch]

Thank you so much!

[cinder birch]

I initially leaned towards WebAR as my preferred option. The appeal lies in the AR content management being web-based, then users could just easily access the AR features through the web. As you mentioned that its lot lighter, it seems more practical for visitors or tourists to use WebAR rather than going through the hassle of downloading a mobile app, especially for a one-time visit to an area.

My problem is the scarcity of learning resources for WebAR. If my teacher permitted it, I would have opted for Vuforia. But I'm not developing an app anymore, but using an existing one instead 😅

[wanton turtle]

The downside to vuforia is it is a 20k/year license now.

But yeah, on a plus note, you'll learn a lot more building a web platform, and connecting it to your app.

For WebAR, we primarily use MindAR or A-frame. I don't use 8thwall, zapper etc as they keep changing their pricing, and I don't like pay per view models for museums and nonprofits.

How can I do localization when starting the app? I'm making an indoor navigation app for a retail store. I think my last big hurdle is localizing the XROrigin ( I assume this moves with the device , and can be used to represent the user ) .. I have a way I think I could do it but for clarity , I would need to make sure the XROrigin object is orientated to the user in real life right? ( position and facing direction in the building ) ... Which I Could use empty gameobjects with location names and create a string qr code to scan at the location ( for position ) then get the camera rotation and set it to the XROrigin?

[gusty wedge]

I've done that and there are no issues on xcode, also my colleague didn't have this issue on his iphone12, I have it on iphone14 latest ios... weird stuff

Another small issue:

on arfoundation I was using a depthmask shader, with vuforia the masked region is black. I suppose is due to a difference in rendering the background camera image. Anyone had this issue?
(is weird because vuforia also has is own depthmask shader and doesn't work, maybe is a metal vs gl3 problem? is black both on my mac and on my iphone)

[still siren]

there isn't enough context to say what's wrong

[still siren]

what is the game / experience?

[still siren]

is your real life location supported by lightship VPS?

[swift bronze]

I'm getting it registered as a waypoint on the geospatial browser

[timber void]

I built an AR app that I am trying to deploy on ios - when I run the build through xcode, I get an error "Library 'GameAssembly' not found". I've read online that this has to do with the new mac os update catalina + ios 17. I still have not found an answer to this problem.

[kindred marsh]

Hello I am trying to use ARFoundation and ARCore for hand detection. But I am unable to do it .

Can anyone tell me is it even available in the latest version of ARFoundation and ARCore

[warm abyss]

I haven't seen any documentation for ARCore hand detection. Where did you get that info?

You can use Lightship ARDK I think?

[livid coyote]

I was downloading the MRTK 3 packages. After that those reports showed up... Had someone similar problems and could tell me what the problem might be. The Unity Version I use is 2022.3.10f1 LTS.

[still siren]

i have successfully achieved streamed unity to mobile safari with augmented reality. so imagine 8thwall, but the content is unity. no webgl. instant loading. hdrp, dxr raytracing, etc. would you be interested in a demo soon? museums and nonprofits can use the hosted streaming and builder for free.

clearly markerless. might have given away whom this demo is really for lol

[wanton turtle]

Thanks for the offer, I will keep it in mind for sure. We do very little AR though, maybe 1 project a month, versus 8 or 9 in VR. For the AR we do it's pretty much all image recognition. So we have things like aframe, and mindar. Although we also have WebAR Foundation for Unity (same makers as MindAR) and it works quite well. But the only clients we've had that want Spatial recognition needed their own full bodied mobile apps and we needed 3D object recognition more than anything

I'll definitely keep it in mind though

Most of our AR stuff is little things as a favor to someone, we just don't do it a whole lot

[still siren]

perhaps this is a painless way to do that. you can test AR directly from editor, as you can see. then, as soon as you commit and push, it builds automatically on the backend, and deploys for you.

anyway i think it's all very clear to you, you know a lot more about this than i do

[severe glen]

Is anyone familiar with the Oculus AR sdk? I'm having trouble making my controllers grab things

[wanton turtle]

Did the demo scenes work?

Not asking to be a jerk - it'll just let you make sure your project isn't misconfigured

[severe glen]

valid question

haven't tried it out yet

give me one sec

[severe glen]

yeah, I think i solved it

I found the only tutorial on the internet that showed how to do this

[small crystal]

is there any easy way to project shadows onto surfaces?? I gotta do one on vuforia, based off an image-target, I tried using an asset previously suggested (https://assetstore.unity.com/packages/vfx/shaders/shadow-receiver-urp-free-228074) but the shadow receiver material doesnt work :(

[warm abyss]

That's my asset :P
Are you using the Universal Render Pipeline in your project?

[small crystal]

eeyup, my bet is on the config but im not sure

[small crystal]

in any case, I had just created a project to try that asset, the proyect has vuforia and your addon, and thats about the level of customization I-m doing, I-m using unity version 2022.3.13f1

the demo scene is also pink as a whole 3>

[warm abyss]

You need to use Universal Render Pipeline in order for the shader to work.
If you do and it still does not work let me know.

Never used vufoairia myself, but if it supports URP and you set that up the shader should work

[small crystal]

yeah I created a project with URP and its showing the same ping color on everything as well

idk how to bug-report it further, so I can wait for instructions on what to do next

[warm abyss]

I'll DM you since this is about an asset

(issue was fixed by assigning the URP asset in quality settings)

[crystal hedge]

has anyone figured out a way to keep additive scenes in sync with a space setup room on quest 3? anytime i lift the headset up, and bring it back down, the additive scene is in a new place,, since scene api repositions the camera and room with how it tracks.

[wanton turtle]

I've never seen that happen, we have some large quest 2 to 3 projects with additive scenes, and we didn't change anything to make them work.

[ebon grotto]

Have you mapped that same room more than once? Early on with Q3 I noticed that I could map the same room 2-3 times depending on where I was standing/facing when initially capturing the scene data. This led to things jumping around like you described, but I haven't had that problem with the current firmware. You could try clearing the Boundary History and Space Setup to see if that helps. There is also a checkbox in Device Permissions that turns on/off point cloud data (with a delete data button underneath).

[crystal hedge]

@ebon grotto I see that behavior after clearing room setup and scene setup. The top level scene anchor always shows as untracked, which i find strange:

all the anchors under it are tracked

I've considered instead of using additive scenes, turning the environment into a prefab, so I would just instantiate it, parent it to the same achor as everything else. the problem with that, is I don't think i can bake occlusion data then.

[ebon grotto]

Ah... I have not used the OVR plugin for anchors. Since this is the Meta/Oculus package, you might try casting a line over on their forums/Discord as well. I'll post this internally for the XR team here and see if anyone knows an answer.

[crystal hedge]

Thanks. I'm in the start discord, and didn't find out any additional info from them

I'm trying to record a video in an AR app that would allow the user to afterwards share the video as one does on their phone. I've seen a few posts about Unity's Screen Recorder but that seems to only be for in editor recordings from what I've seen. Is there something else that can be used?

[vital void]

I am trying to figure out how this sample uses CollaborationData to orient each device with one another to connect the devices to the same session. I am trying to do the same thing with lidar data instead of CollaborationData and want to see how it is done with CollaborationData to reference, but I am having trouble understanding the code in the sample.

[void zinc]

How can I account for anchored objects using arcore moving with the phone camera or losing track of the position of the Gameobject in the 3d space any known implementation examples to fix these problems? I am having doubts that my Samsung S21 is capable and my objects cant stay anchored no matter if i show feature points or planre detection while moving my objrect and having it stay where its currently anchored. Dont unederstand why Arcore is doing this and cant find anything to solve this...

[still siren]

what do you mean, connect devices to the same session? all the devices have a distinct ARSession, and the middleware (ARKit) has a way to share and ingest mapping information from multiple cameras (and hence interpret foreign poses with respect to the device's pose correctly)

what do you mean do the same thing with lidar data? unless you have a SLAM solution, what are you going to do with that data?

[slim herald]

Hi,
I needed help as I am very new to AR Development. I am creating an App but my model which is Present in the Scene Tab is not appearing in my Game Tab. Could someone either DM me or Tag me explaining how to fix this? I am confused as to how to add my model so that it appears in the Game Tab so that it appears when I'm running my AR App.

Thanks!

[still siren]

are you working from a tutorial?

[slim herald]

I am kind of working from two tutorials at once, hence the problem above. What do I have to do to fix this issue?

If i selected the trebuchet in the Scene Tab, the size of the model is 100, 100 and 100. Still I don't think its appearing in the Game Tab. Also, the model is placed around 500 on the x axis, so would that cause the problem and not allow it to show up in the Game Tab?

[slim herald]

@still siren any steps to fix this?

[hybrid perch]

Yes, if the object is out of view of the camera, it won't be visible in camera

You can select the camera in the hierarchy to see its bounds

[slim herald]

Okay, Thanks for clarifying.

[severe olive]

Does anyone know why moving children objects in code of an object that is used as a tracked image prefab makes them disapear?

Update: I think I found it, I was using transform.position when moving them instead of transform.localposition

[severe olive]

Yeah... yeah that was it. Somehow I didn't realize that the object wouldn't be at 0,0,0 when it was following an image around.

[still siren]

there is a lot going on so i'm not sure

[severe olive]

What is your camera pointing at?

[slim herald]

I fixed the issue, the problem was that my model was not in front of the camera and was 500 units away from it. Thanks for the help anyways!

[vital flint]

hello newbie here, I'm trying to make AR for this and when i apply material i can't see it, it's White but when i see the bottom it's already have the material. I assume it was the light but i can't delete the light , so how to delete it and is it the light that make it hard to see? thank you

[wanton turtle]

Well some of those things only you know. If it's the light, spinning it would change where the white part is. To me though it looks like there are two materials on that object, and only one has a texture on it.

Aa for the light, click on the Directional Light in the list and delete it 🙂

[vital flint]

Oh i see thank you , but because of the prefab/child thingy i can't seem to delete it . As for now i just lower the intensity of the light

[hybrid perch]

You can disable it with this toggle

Alternatively disable lights import on the mesh import settings

[vital flint]

oh thank you so much , i will try it

Hi everyone!
Does anyone have experience testing an AR app with Unity Remote 5? I'm making an AR app for ios and testing with an ipad. When I build my app the camera appears to be working well, but through Remote 5 I only see a black screen, just as in the game view in the editor. From the ipad settings I gave Remote 5 access to the camera, I wonder what could be the problem. Anyone else had this? 👀

[true stag]

Unity Remote 5 will not work with AR Foundation, if this is **absolutely **required it's possible there may be something on the asset store.

[slim herald]

Guys, I had a Question. I have placed a UI Image on my Canvas which has a Button Component and there is also a Model in the Same scene outside the Canvas which has a "is Kinematic" Ticked. I want it to be that when the person clicks on the Button, the "is kinematic" will be disabled. I know how to write the Script for that part but, I'm confused about where to place the Script. Should the script be placed on the button with the "New Script" Component or should it be placed in the Button Component with the "On Click()" ?

[warm abyss]

You can place the script where you want in the scene. You need to activate the method which does the changing to the event on the button

[slim herald]

I need some help again
I have written a script to disable "is Kinematic" in Rigid Body and also destroy a Hinge Joint which allows my model to move, but I created a Reset Button which brings the model to the original position and enable "is Kinematic" and create a new Hinge Joint but, my code is not working because instead of resetting my Model, it is moving my UI Image with a Button Component . Could someone check my code and let me know where I am going wrong!

public Button ResetButton;
public Rigidbody Weight;
private Vector3 initialPosition;
private HingeJoint originalHingeJoint;
public GameObject Ball;
void Start()
    {
        // Store the initial position of the object.
        initialPosition = Weight.transform.position;

        // Get the initial HingeJoint component
        originalHingeJoint = Ball.GetComponent<HingeJoint>();
    }

    // Update is called once per frame
    void Update()
    {
        ResetButton.onClick.AddListener(ResetOnClick);
    }

    void ResetOnClick()
    {
        // Enable isKinematic
        Weight.isKinematic=true;

        // Move the object back to its initial position.
        transform.position = initialPosition;

        Destroy(Weight.GetComponent<HingeJoint>());
        HingeJoint newHingeJoint = Ball.gameObject.AddComponent<HingeJoint>();
        newHingeJoint.connectedBody = originalHingeJoint.connectedBody;
        newHingeJoint.anchor = originalHingeJoint.anchor;
        newHingeJoint.axis = originalHingeJoint.axis;
    }

[hybrid perch]

transform.position refers to the object the script is on

Presumably you'd want Ball.transform.position

[slim herald]

Yeah, I realized that . Thanks!

[hybrid perch]

By the way @slim herald you should not have that line in Update, it should be in Start

The way it is now means that you attach a new listener every frame. You just want to do it once

[slim herald]

Okay, I understand. Thanks for your help!

I am currently developing a mixed reality app for the Meta Quest 3. I've got a 3D space canvas with an image that serves as the background. As of now, it's just a simple black cube with rounded corners, which has around 50% opacity.
That's not very immersive, so I thought to myself, why not make it like the Apple Vision Pro, where the background is blurred.
Does anyone know how difficult it would be to implement something like this? Is it really just a simple blur shader applied to the background?
Because I haven't seen anyone implement this before.

[wanton turtle]

Does the device you are running it on support arcore? Maybe it's a compatibility issue. ..

[brisk obsidian]

Hello guys, can anyone give me a quick rundown on how I can detect the color inside of a small area of the camera using AR.Foundations? I'm trying to get the Camera texture from the ARCameraFrameEventArgs and then specify the bounds of that area of the screen and comparing the pixels to the color I want to get, but my app stops at "eventArgs.textures" and I'm having issues debugging

[still siren]

you can't blur the camera feed. you have no access to it, and have no way of indicating to the API that you want to use it. afaik, the render buffer for quest passthrough uses alpha. the vision pro also does not let you access the camera feed, and unity implements support for it essentially via a shadow scene graph

[still siren]

the approach you are taking is impracticable. what is your goal?

[warm abyss]

Maybe if you use a custom material for the passthrough you can mess with the UVs to look blurred?
Randon thought, not sure if that can actually work

[brisk obsidian]

So I have a cube, and the player is given a color they have to find. Upon pointing the phone camera (or more specifically, a particular region of the phone camera) at something in the real world with that color (within a certain threshold of course), one of the cube's faces is painted with that color and a new color is given. I'm having issues with the IRL color detection side of things.

[still siren]

it's not composited by unity

[still siren]

have you tried lightship ardk? there is a long journey on doing stuff like this performantly. you can't practically read the camera texture with ReadPixels, it will be too slow

[wanton turtle]

You could give a target and only read a smaller subset of pictures though. Or run it through open CV too.

But yeah if you expose the camera material at the arcore / arkit level you might be able to do something outside of Unity as well.

[void zinc]

My biggest question is Lightship? or the convienence of Unity with the ARCore with its sub optimal Anchor system.

Hi there! are there any tools that allow XR interactions with custom hand Tracking? I just need proper information on how i can improve basic xr interactions such as grab, throw, pinch without any collider issues.
(ps. not talking about XR toolkit interactions or MRTK)

[warm abyss]

Pinch can be done by calculating the difference between finger tips.
Hand poses can be done with rotational comparison

[open trail]

@hybrid perch Thanks, it looks the most advanced tutorial, although its only VR focused. And I can keep up without headset while waiting to acquire one. Btw Is there other more interresting options than the Quest3 in the same price range ?

[hybrid perch]

I don't know about the AR tutorials, it's more limited. Again I would go for the most recent ones wince AR Foundation has changed a lot in the past

And no nothing compares to the Quest 3 in that regard, I know some people have been pretty happy with the Pico Neo 4 though

[open trail]

Ok I'm good to go, thanks

[wanton turtle]

The XR openxr hand example also has an example of pretty detailed tracking. I've done a few custom tracking systems with it (i.e. telling when someone is making a fist, curling a finger, pointing, etc) and it works very well. If you are going down the Quest 2/3 route that is.

But yeah you can definitely just get the raw finger & hand rotation data and create your own pose tool if you want. Not sure if that's the question

Hey everyone, I'm a Product Manager on the XR team and want to share our latest roadmap (https://unity.com/roadmap/unity-platform/arvr) regarding Unity’s XR offerings. This should help you understand what’s coming down the pipeline, and more importantly, provide a channel for you to express what features are most important to you. This will be a critical part of our development process to validate what features we work on next.

We’re committed to reviewing all the feedback that comes through the portal, so please vote for features that are important to you and leave detailed explanations in the corresponding feature cards to help us understand your needs. If you feel like something is missing from the roadmap, feel free to use the “Submit a new idea” card to share your thoughts.

hey, my image tracking only works when im kinda close like 0,8m to the marker. im using an ipad camera (which is actually kinda good) and the contrast between wall and my marker is also very very good, but it still doesnt start tracking until im close it.

anybody know why?

[hybrid perch]

This is just the behaviour in AR Foundation as far as I know It's really frustrating. When I tested on Android it seemed to always only track when it filled up at least 50% of the screen width

[wanton turtle]

I'll second that...

[soft ginkgo]

Hi guys, is there a way to speed up plane detection using ar foundation? It seems to be really slow sometimes

[warm abyss]

I assume on android?
Or also IOS?

Which Unity version and AR Foundation version?

[soft ginkgo]

Android, unity 2022.3.12f1 and AR Foundation 5.1.1

[true stag]

I'm not aware if there's a way to speed up plane detection on AR Core (android), is it possible your phone is limiting processing power of the app, via a low-power mode, or battery saving setting, or perhaps your environment has low points of reference in it?

Having a point cloud enabled in the scene can let you see any dots that are tracking in your space

[soft ginkgo]

The phone is not limiting the app to my knowledge, I will try to use point cloud to check the dots, thanks for the suggestion

Yes and yes although it would be weird.

It seems to just be someone pretending to use passthrough for the first time

What I will add is that you can't read a monitor very well with the Quest and pass through

[cloud bolt]

helllo anyone is online?

[icy silo]

how much unity should i learn to become a ar developer? should i become a master or basics is enough?

[wanton turtle]

Assuming ARFoundation, it can be harder to troubleshoot. Sometimes the testing can only really be done on device (which is slower and takes patience), so it helps to have a good idea of how the ecosystem works

It also depends a lot on the complexity. But it helps to know 3D well (how to animate, rotate, move, place, etc), UI (landscape and portrait mobile design) and things like permission requests, camera layering, building configuration for mobile and all that jazz.

Hey, maybe a very basic question, but I couldnt find enough evidence in the web by now, if scanned point clouds and other information (e.g. Plane positions) could be serialized from ARFoundation for later reuse. Like revisiting a location and get positioned without recreation of a point cloud but testing an existing one. Talking about native features under ARFoundation, ARKit seems to support access to that data, while ARCore seems to support with the use of Cloud Anchors, which are only temporary sadly. But cant tell, if that is true. Any1 with hints here? Thanks a lot.

Hey everyone. I'm looking for and AR sdk that I could use to build a desktop application (ideally for linux and macOS) that would use a webcam to track some simple image targets. I know about Vuforia, but that doesn't run on linux unfortunately. Would something like that be possible with ARFoundation, or should I be looking elsewhere?

[hybrid perch]

AR Foundation does not run on desktop

[hybrid perch]

I've tried this before with ARKit directly (not via AR Foundation) and it works, it's a bit fragile though because you never know how much change is gonna count as a mismatch. Especially for outside with weather etc but anything non-static can be an issue

Thanks. Yes, I did that with swift already few years back, but now was looking to combine both platforms using unity, as I have experience in unity too, just not for AR. But I do not know, if ARCore ever did what they planned with persistent cloud anchors and if both would then be available via a unified API on AR Foundation side.

[hybrid perch]

I think ARCore has their own focus on the cloud anchors? To achieve the same thing

[north bramble]

Probably yes. So that might be something where one has to go device specific, while trying to keep the rest unified. But I'm probably to unexperienced in the AR Foundation thing and might have missed the best practice here. Docs didn't help (me) so far.

[wide oriole]

thanks for the heads up. are you aware of anything else I could use for that purpose?

Oh boy transparency

https://unity.com/unity/features/arfoundation from here

[wanton turtle]

OpenCV also works in a pinch. I think EasyAR claims it but their platform is really unreliable these days.

[true stag]

Also, Apple ARKit is currently also the only one to support object tracking, which isn't mentioned on that graphic. https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@6.0/manual/features/object-tracking.html

[north bramble]

Thanks, but the docs speak from persisted anchors only in combination with an ARWorldMap in ARKit.
" In some scenarios, you can create anchors in other ways, such as loading an AR World Map on ARKit which includes saved anchors."
Still seems for me, while anchors are available unified, injecting persisted anchors from earlier can only be done with ARKit. Would love to get proofed wrong here 😦

[idle chasm]

Hi. I am new to unity and XR development. I am following this tutorial https://youtu.be/D8_vdJG0UZ8?si=0BX08V_WIMjsRU_k&t=378
he is unfortunately using ver 57
seemingly the meta integration has changed. I am looking for some guidance to replace the OVRcamerarig
and the OVRControllerPReFab
assets
Can anyone direct me on this ?

[midnight narwhal]

Hey! Need some advice/tips.
I have this use case that uses realtime tracking with the Hololens 2. Are there any external (accurate) trackers that are compatible with Unity?
So i can stick a tracker on a moving object and the Holograms move along with it.
Thought of an Arduino but don't know how accurate that is.

[true stag]

AR Foundation does not currently have support for persistent anchors, the actual platforms themselves might support them like ARKit, but they aren't currently used in an AR Foundation interface.

[north bramble]

Thank you for clarification.

[true stag]

Is it random or does the animation actually have the position as part of the values it controls?

[still siren]

when you say a video call, do you mean showing a remote ordinary video locally in a rectangle? or the local exterior-facing camera's video to a remote user? or a local unity camera to a remote user?

[trim dune]

Has anyone tried ARFoundation with Quest 3? I'm wondering if it still enables all the Quest 3 room auto-mesh features, or if ar foundation requires you to manually place every object

[true stag]

Meta quest, at least on 2, receives the information about your room when you have a plane manager enabled if I'm recalling correctly, you shouldn't need to re-track all the walls/floors/supported furniture every time in quest, and I don't believe quest 3 is different there.

[idle chasm]

i am folllowing a tutorial that uses Metas v57 SDK. They have updated to v60. Some things are different and I don't know how to resolve. Can anyon help

[true stag]

You'd need to describe what differences you're seeing, and what you're trying to do, so we can know what the proper way to do them now is.

[delicate aurora]

hello, just trying to use arfoundation to have a image tracking AR. i'm wondering how to access the spawned arprefab's game object? i have 2 game object inside the arprefab i want to toggle between the Cube and Sphere for the spawned object of the image tracking AR

and i'm using XR Origin instead of AR Session Origin

[idle chasm]

what this comment in relation to my question

[true stag]

You say that you're following a tutorial to do something, and it's not working because it changed, so then tell us what you are trying to do.

[true stag]

If you're using a script to spawn the prefab, I'm sure there's a way you can edit that script to give you access to the objects it spawns and you can then do as you wish with them?

[idle chasm]

@true stag The v57 of meta sdk has prefabs to hide the planemesh, volume and add global collisions with the global mesh. In v60 these had been renamed. The meta documentation also hasn't really been updated for v60. I eventually found what I was looking for and have what I need

[harsh epoch]

With v60 of the Meta SDK, anybody else having an issue where using OVRSceneManager and OVRSceneModelLoader for a fresh install will prompt the permission then jump to the room creation process, before coming back to your app and failing to load the model?

It will only load the model if I then remove the headset and put it back on to force focus or restart the app. Only then does my scene have doors and walls from the room setup.

[wary elk]

Hey Guys I am using Unity vuforia in a project and I build it and tried it for pc , I also have the webcam connected but it ain't detecting it in the build , what am I missing?

[delicate aurora]

I'm building to android with ar foundation unity, but the camera stops after 1 second. anyone knows why?

[halcyon sable]

I am trying to build an AR mobile application in unity. What i need to do is able to classify these shapes in the image such as Triangles, Lines, Arrows and render their 3D counterpart above it. I am not going for a marked based approach and so far I've tried contour detection and template matching with an open cv extension but i don,t feel i am on right track. Any insights on how do i achieve it

[frigid surge]

you can use MediaPipe for that (https://developers.google.com/mediapipe) there are already Unity integrations.

[odd axle]

hey can i dm you about this?

[rancid epoch]

Guys good evening ✨

Come again the name of an AR with masking surface detection?

Can't recall the name...

[rancid epoch]

https://youtu.be/fvA7v5noVjc?si=3l1sYNwYqO6yqAIc

things like this

[balmy basalt]

are you around max ?

[warm abyss]

Semantic segmentation?

I think that's the name of the tech in lightship, probably similar for other providers

[rancid epoch]

noted

but sorry I mean the Depth API, it's crazy when the mesh object be able to hides behind the object (just like masking)

but can you elaborate about it ?

[balmy basalt]

pretty interesting but which smartphone actually afford that google space invaders AR

[warm abyss]

That's depth occlusion. What do you want to know about it?

[wide thunder]

I was trying to follow a tutorial for a 360 video portal, but it's for ARcore and can't find an equivalent video for ARkit (it has to be 360 portal, not just a portal with 3D architecture inside) Someone said I can adapt it for Arkit, but the code will be different, and I'm a beginner following by rote because I don't understand the code yet. In addition, there must be other customizations needed, because he uses ARcore session and I figured there'd be ARkit session--but all I'm seeing is AR session (don't know if that's the same). Any chance someone can tell me the jist of what I need to do differently in order to adapt this guy's instruction but for iOS? Alternatively, if you know of a tutorial that's 360 video portal but for ARkit I'd be incredibly grateful as well; but I haven't found one thus far. Thank you!

Actually, it seems this video is massively outdated, so I don't think it's workable at all.. Any recent similar tutorial recommendations for ARkit?
https://www.youtube.com/watch?v=ec6WgO5C8CA&t=2s

[warm abyss]

Why shouldn't this work on ARKit? Unity is cross platform, right?

I've made a lot of portals with URP's stencil buffer, then just switch around some layers or shader values when crossing in and out of the door :P
https://youtu.be/EzM8LGzMjmc?si=okAt6pZ_jyOCfHkC

[wide thunder]

Thanks for linking your tutorial here, Dylan! I'm checking it out now. And yes, the other one is supposed to work for ARkit, the problem is I'm a beginner and don't know how to make those adjustments without a step by step guide.
But the bigger issue, really, is that his video seems out of date. I was following his guide step by step (without modifying anything) and he has something called AR Core Session, but that does not seem to exist anymore. I was able to find something called AR Session, and figured it was the closest thing to it, but the parameters look nothing like what he has.

Follow up question to my last one: Since AR Core Session no longer seems to be a thing in Unity, what is it called now? Is AR Session the same thing or no?

[warm abyss]

Which adjustments?
Just make it for AR Foundation and Unity should just make it work

The AR Core session is now just AR Session or XR Origin.
It shouldn't matter much

Just continue and see if it works

[wide thunder]

Thank you! And I guess I was misinformed when I thought there were adjustments I'd have to make. Some guy in comments said 'the code will be different for ARkit' but I'm just going to proceed with following it as is.

[wide thunder]

Sorry, one more question, and it might be a ridiculous one at that: I can't find 'session config' when I go to Assets---->create--->XR, nor does it show up anywhere that I've looked for it. Has that changed too? The most up to date guides say it should be there.

[true stag]

Any more context what you mean by "session config"? Like what are you attempting overall?

[frigid surge]

hi, sry no notification Oo anything I can help you with?

[wide thunder]

I was following an outdated tutorial, but I've now switched so I don't need help on session config anymore. I'm about to ask a totally different question soon, haha

Is there a way to immerse the player in water using easyAR, (like in this video) https://www.youtube.com/watch?v=LkVHlWBDiEU or is that outside the scope of what easyAR can do?
What are the main parts to doing something like this, so I can look up a bunch of tutorials to take me in that direction?
Thanks so much!

[slim herald]

Hi Guys,
I needed some help with my AR Project which I am trying to make as a beginner.
In my AR Project there is an arm and a ball, when i click a button the hinge joint between the sling arm and the ball is getting destroyed.
Then there is another button to reset the objects to their original state, but the hinge joint between the ball and the sling arm are not appearing in the properties tab when running the app and as a result there is no hinge joint being created between the two objects and I am having a hard time figuring out how to fix this issue. Can somebody help me fix this issue?

My full code is given below:

public Rigidbody Weight;
public Rigidbody MainArm;
public Rigidbody SecondaryArm;
public Rigidbody SlingArm;
private Vector3 initialPosition;
private Vector3 initialPositionBall;
private Vector3 MainArmInitialPosition;
private Vector3 SecondaryArmInitialPosition;
private Vector3 SlingArmInitialPosition;
private HingeJoint originalHingeJoint;
public GameObject Ball;
public Button ResetObject;
public Button ReleaseBallButton;


void Start()
    {
        initialPosition = Weight.transform.position;
        
        initialPositionBall = Ball.transform.position;

        originalHingeJoint = Ball.GetComponent<HingeJoint>();

        MainArmInitialPosition = MainArm.transform.position;
        SecondaryArmInitialPosition = SecondaryArm.transform.position;
        SlingArmInitialPosition = SlingArm.transform.position;

        
    }

void Update()
    {
        ResetObject.onClick.AddListener(ResetObject);
        ReleaseBallButton.onClick.AddListener(ReleaseBallOnClick);
    }

void ResetObject()
    {
        Weight.isKinematic=true;

        Weight.transform.position = initialPosition;

        Ball.transform.position = initialPositionBall;

        MainArm.transform.position = MainArmInitialPosition;
        SecondaryArm.transform.position = SecondaryArmInitialPosition;
        SlingArm.transform.position = SlingArmInitialPosition;

        HingeJoint hingeToDestroy = Ball.GetComponent<HingeJoint>();
        if (hingeToDestroy != null)
        {
            Destroy(hingeToDestroy);
        }

        HingeJoint newHingeJoint = Ball.gameObject.AddComponent<HingeJoint>();
        newHingeJoint.connectedBody = SlingArm;
        newHingeJoint.anchor = originalHingeJoint.anchor;
        newHingeJoint.axis = originalHingeJoint.axis;
    }

    void ReleaseBallOnClick()
    {
        HingeJoint hingetoDestroy;
        hingetoDestroy = Ball.GetComponent<HingeJoint>();
        Destroy(hingetoDestroy);
    }

If anyone finds a solution to this, could you ping me or DM me as I really need help and am stuck solving this issue since some time!
Thanks!

[true stag]

Looks to me like the main parts would be accessing the rendered image of the background, since the water does seem to be distorting the images behind it, either with a shader if it does work, I'm not sure if shaders do have access to the background render image or not, or you can use the CPU image method to grab the camera image feed and feed that into a shader that just takes the image and distorts it behind it, I'm not 100% sure but that sounds like terms you'll want to look up how to do at the very least.

[true stag]

First immediate tip is I'd caution putting the add listener function in your update function. Try putting it in the start function at the end instead?

Also your task isn't exactly AR specific code, so you may get better help in another general coding place

[true stag]

You're trying to restore the values of the original hinge joint to the new joint, but you've already destroyed it, so that's not going to get you any proper values, would it?

[austere ember]

hey i have a specific issue with using a minimap camera on my AR scene can i just ask my questions here ?

[slim herald]

I tried to put the add listener function in the start function, but whenever I do that and run the AR environment, the functions of the buttons are not executing (meaning if I click the button, it does nothing). Am I doing something wrong whenever I place it in the start function?

[slim herald]

Do you have any other way to go about the task as I need to release the ball but when I click the reset button, I want the ball to be reset with the new hinge joint connected to the sling arm. If there is an alternate way to go about this, please advise.

Thanks.

[true stag]

does disabling the hinge joint drop the ball?

[slim herald]

If the hinge joint can be disabled, then the ball will be dropped. But if I reset the ball and enable the hinge joint will it still be connected?

[true stag]

It should be connected it you place the ball back where it will be, and re-enable the hinge joint, I'm not an expert in unity physics components, again this is an AR help channel

[slim herald]

Okay, I'll try that. Also which channel should I put my doubts in if I need to in the future related to my project?

[true stag]

perhaps #⚛️┃physics or #archived-code-general

[slim herald]

Okay, thanks for the help!

[true stag]

Welcome!

[wide thunder]

Thank you!!!

[wide thunder]

I'm sorry if this is a noobish question, but what is the best way to flood the floor in AR with water (like 2 feet)? I don't mean fluid simulators, and it doesn't need to be realistic. Is it like tracking a simple mesh to the ground plane and texturing it with 'water'? Is that how a beginner could do it?

[true stag]

You could check for the lowest plane and then place a plane and color it like water

That's the simplest way

But it won't have the visual effects like the video showed

[obsidian lily]

I want to add images to XR reference library via an editor script, but I am not able to make a new XR Reference Imnage which I will add to the library. Is there any work around or a proper way of doing this?

[true stag]

An image library is a scriptable object, so you can save it and load it like a file essentially, you should be able to find proper documentation and methods of loading new image libraries at runtime https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@6.0/manual/features/image-tracking.html#create-a-reference-image-library

That being said, this page also has a section detailing how to add images at runtime if the system supports it. https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@6.0/manual/features/image-tracking.html#add-new-reference-images-at-runtime

[flint basin]

But keep in mind that your images have to maintain a certain quality score, the arcoreimg tool is currently bugged in 5.1.1

[true stag]

Can you explain the bug you mean?

[flint basin]

It occurred to me that having a ReferenceImageLibrary attached to an AR Tracked Image Manager caused the project to crash on the mobile device. Reason being having at least one image with lower quality (below 300x300) within the Library itself, I reproduced it when I dynamically added images to it. The bug is resolved in AR Foundation 5.1.2

I think I can find the issue tracker link

https://issuetracker.unity3d.com/issues/android-crash-on-android-when-artrackedimagemanager-component-is-added-to-the-ar-session-origin-game-object
That must be the ticket related to that

[true stag]

the build crashes or the game crashes?

[flint basin]

Game crashes

[true stag]

Hm, I think I was involved in the fix for it, so hopefully that fixed version is out? Or have we yet to release that version

[flint basin]

It was said that it would release anytime now after the winter break, might be coming next week

[true stag]

I can check to make sure we do have a plan to get that fixed version released

[true stag]

We do continue to have plans to release it soon, I can confirm that

[wanton turtle]

You should also know you can only have one image library in your project, or it will fail to build in xcode on Apple

[woeful ice]

Is there any tools to debug ar applications?

[wanton turtle]

Sure, profiler is a good one, but mobile devices all have logs and performance tools you can use too.

You can also debug directly on device in most cases.

[woeful ice]

By pluging my mobile device to my computer and running the app on unity ?

[flint basin]

By enabling Developer Mode and USB Debugging, you can then directly run and build onto the connected device. Alternatively you could use Android Studio

[wanton turtle]

https://docs.unity3d.com/Manual/android-debugging-on-an-android-device.html

Comparatively on Apple you could use xcode

[wide thunder]

My skybox does not show up on my device when I'm running the app, but it does show in the scene editor and the game preview. I have the AR camera set to clear flags: skybox and also have the same skybox material in the environment tab. What usually causes this?

[wide thunder]

I know I just asked a question, but if I can add one more: I have a scene with a water surface, but I do not want users to be able to be able to move their devices under the surface and see what's 'underwater' (there's nothing there). How can I prevent them from going below the water?
Thanks!

[hybrid perch]

In AR you can't really prevent the user from moving, but you can decide how you respond. You could have a trigger collider under the water that fades out the camera for example

[wide thunder]

Thank you! I'll look into that

[hybrid perch]

The AR Camera is hard coded to show the camera rather than the skybox, I don't think you can disable that. It would also kind of defeat the point since it's no longer AR?

[wide thunder]

The idea behind it is to be like a portal with a 360 video background. I've seen AR tutorials where they do that, so I assumed it would be possible. If not, then my mistake.

[hybrid perch]

Do it with a inverted sphere, not on the skybox

[wide thunder]

Thank you! I had somehow forgotten that's how it was done, not with skybox. Appreciate it!

[urban goblet]

Hello I am trying to integrate pulse oximeters in real time from Arduino using max 30101 hardware sensor and want to know if it's possible to integrate to unity3d. If so can someone help me? goal is to deploy all of this onto Hololens

[wanton turtle]

It's really easy to add a Bluetooth module to anything arduino, and that would give you a lot of control via unity, web apps, mobile apps or whatever platform you want to go with. There are also serial arduino assets you can buy from the asset store if needed.

[urban goblet]

I'm using ardity

[wanton turtle]

I havent used it, but I'm sure with the appropriate cable it would work fine. I'm not sure there is anything to help you with, it sounds like you are already connected up

Skimming the comments though, just keep in mind some people needed to change some of the serial settings to make it work

With serial or Bluetooth though you can send any data or strings you want between the devices. So you should be able to just tunnel the data across. I'd avoid things like json just because of the severe arduino memory limitations

[wide thunder]

A couple questions, and sorry if they seem basic but I'm wondering:

1. Since every tutorial I've seen shows how to do tap and place (but I just want my object to spawn on the ground at the start, unprompted), what steps do I omit in order to get rid of tapping--do I ignore the raycast compoenent, for example? Also, with tap and place, what might cause an object appear far above the surface, despite the fact that the horizontal plane tracking appears to be working?

2. What is the best way to set up glowing objects for augmented reality? I've tried following videos for URP involving emissive materials, but the effect does not carry through in AR, whatsover. Is luminance/glow not recommended for AR? For context, I'm trying to have objects that glow underwater, and the water is what is being tracked to the ground. The water is partially transparent and is being textured as though it were a night scene, if that makes sense, so that the glow can show through--but it just does not appear glowy. If anyone can weigh in with tips on implementing glowy material for AR, I'd appreciate it.

Thank you!

[crystal oar]

Has anyone else noticed the flickering with arcore image tracking?

This was not the case back with 4.2.x but for some reason it's happening even on 4.2.x till 6.x

[true stag]

Can you describe the flickering you mean? Is the image flickering, the tracking is spotty, or the prefab you placed on the image is flickering?

[true stag]

1. I'm unsure, you would be best off understanding the script first before wondering "what's the least I can do to reproduce only what I need", so I would encourage you to play around or test your ideas! In case, if I understand correctly, all you want to do is raycast as soon as possible downwards, so you could do a manual call to the raycast manager and set an object where it hits, problem with that is depending on the platform, the planes may not even exist right below where the camera starts, and this could cause your method to fail, so again, I encourage you to experiment in learning how planes, raycasting, and object placing works!
   You can find a working example on our https://github.com/Unity-Technologies/arfoundation-samples github

2. The rendering issues could be because passthrough may destroy or not respect alpha channel readouts on "glowing" objects, you may also need to check the shader or the material settings as well to see if you can get it to glow properly with alpha values fading out.

[crystal oar]

It's the prefab used to apply the the tracked image coords.

Here the video:
https://youtube.com/shorts/Up9lqmSFdaE?si=Odp-WiIkOmjugnIv

[warm abyss]

More often called drifting and it is very prominent on android.
You could try (after making a backup) AR Foundation 6.x in the latest beta version to see if that helps.

[crystal oar]

Tried 6.x same issue and this occurs even on iOS

If I "don't apply the rotation of the tracked image" then this issue doesn't occur

[warm abyss]

Huh, interesting
Does it also happen if you onluy place the 3D object once and dont update it this often?

[crystal oar]

U mean some kind of delay?

Or just don't update?

[warm abyss]

Yeah this might be because image tracking is a bit wonky.
I'd spawn it once if the image does not move at all, since the object then should be anchored there already

[warm abyss]

Don't update

Unless you want the image to move as well

[crystal oar]

Yes if u disable tracking after the add event then augmentation remains stable

[crystal oar]

Even if the image doesn't move the user's will, so continuous tracking is required

[warm abyss]

Otherwise smooth out the position and rotation. Kinda loke smoothdamp

[crystal oar]

I tried to round off the rotations

It somewhat helps

[warm abyss]

Why?
AR foundation is 6DoF. So the image should stay even if not in view

[crystal oar]

No I mean if the image is on the table and the user is moving and then again tracking it with the image to it's new position

[warm abyss]

So the image is moving?

[leaden peak]

Heloo there I had a quick question about ARcore
I don't have the ARcore supported phone so would I still be able to create with AR in unity?

[warm abyss]

I mean yes, but not test it.
You can try to sideload the ARCore services with maybe some succes as well. Otheriwse look for a cheap supported phone.

You can also use AR frameworks that do not need arcore, with less features

[leaden peak]

So the only option is change frameworks? Or looking for new phone?

[warm abyss]

Mostly yeah.
You can test stuff in editor, but testing on an actual device is highly recommended

[leaden peak]

Yes I actually tried every way whole day

But I still can't see when I play it on my phone

[warm abyss]

Well yeah, that is what no support means.
Is there something specific you had in mind?

[leaden peak]

I thought downloading a modded ARcore might solve just my assumption

Thank you for telling!

[warm abyss]

Sideloading could fix it with varying levels of succes. But the chance of actually working is quite low

[crystal oar]

It could

[leaden peak]

I see, I will keep that in mind
Also sorry to cut in between the conversation

[warm abyss]

Maybe check if the distance is over a certain treshhold. If so, move it, otherwise let it stay

[crystal oar]

So there's really no better solution I'm guessing? Bcs my current implementation does the same thing round off the rotations, check for distance if under threshold apply round off rotation & postion else position

:/

Is it bcs of the poor image tracking model? Or there are other contributing factors?

[warm abyss]

Image tracking is a bit iffy sadly, especially in 6DoF.
More details and contrast in an image can help a lot. Lighting can help. Printing the image can help.

[crystal oar]

What about arkit? Does arf use the arcore image tracking model when building for iOS?

[warm abyss]

No, for ios it uses ARKit. Usually more stable than ARCore, but that's managed automatically

[crystal oar]

That's interesting as I don't see any major diff with the drift issue. The only diff I saw was better image recognition which could also be bcs of hardware

[warm abyss]

Maybe a different kind of drifting then haha

[crystal oar]

Maybe I'll need to investigate more

What's the script tracked image from arf do?

[warm abyss]

Usually if you just place an object somewhere on android with movement it wobbles a bit, and on ios this is a lot less. But maybe that is fixed as well now

But I cannopt help much more. For longer discussions also post it on the forums :P

[crystal oar]

I sussed the same thing maybe it's the human movement not like a gimbal so I put it on a tripod and tried bunch of different arf versions

Anything after v4.x has very poor image tracking in general forget about drift

[warm abyss]

If you have a proper reproduction case for an issue which is not apparent in older or other tools, file a bug report and m,aybe it will be confirmed and fixed :P

[crystal oar]

I have already posted no response yet there was some bug with pose driver which seemed to have fixed a similar bug with unity but even that fix didn't help me

[crystal oar]

Yeah ig

[wide thunder]

Thank you for answering my questions! Some of this goes over my head, but I'll be keeping it in mind as I'm sure it will make sense as I continue to learn.

[true stag]

Happy to help! Hope you learn what you wanted to!

[wide thunder]

Is it possible to create the illusion of a twilight or dusk scene in AR during the day? I thought maybe a 360 material on a sphere (lowered transparency) might do something towards this effect, but it definitely looks weird. Someone suggested that camera shaders might be the answer. Can anyone confirm this before I dive into it, and is it even possible to darken the daylight or otherwise superimpose a darker scene onto a daytime environment?

[warm abyss]

You can use sky occlusion to replace the sky.
And indeed use a custom AR shader or in 2022+ you can use a fullscreen shader graph to darken the scene

[wide thunder]

Thank you! Looking that up now

[warm abyss]

1. Update Unity. There have been many fixes
2. Check the logs in the console

[stray chasm]

i found the solution.

by deleting that file keystore, i found the solution.

Sorry for asking so many questions in here, but something I've had issues with is a little fragment of something red appearing in my build, but I've dug into every part of my scene and there is nothing there. It looks like a compass meter just floating on screen (doesn't follow the camera) Has this been known to happen to anyone, or does it sound like something left behind in my scene, despite my finding nothing that looks like that?

[wide thunder]

And yet one more question: I understand that AR session origin is depracated and we use XR origin now, but why does the AR Core template still come with AR Origin by default? (And I have updated to the newest Unity)

[true stag]

It could just be a name thing, the prefab/game object has a name, but the component structure is what is the effective part.

Hello Guys,
Does anyone building for Vision Pro using Unity? in production .

[wanton turtle]

Given they don't start shipping until mid-march, and that they put a money grab pro requirement in front of it - I doubt many people on here are using it for production. There are a few studios messing with the SDK on the Unity slack group, and some of the vision pro devs on there. In other words it might be better to ask on slack

[cosmic stump]

Thank you. Is there any link unity slack channel ?

I'm actually wrong the Unity one is like this discord and owned by unity staff. It's a bit dead. Its the VRDevs slack that has an active apple channel on vision pro

Hello, I have scanned a few engine parts using an ARTEC 3D scanner (the uploaded file is an OBJ file) and would like to put them into the Mesh filter so I am implement and use them in unity. However, it's not working, and I'm getting the following error message:
Could someone tell me how to resolve this problem?

[wanton turtle]

I'm not seeing an error message, but yes a none for mesh won't draw anything.

You may need to right click on it and press reimport, just a best guess

Hello everyone, I'm new to AR on Unity. I'm trying to understand how the logic works in general. I'm trying to make an AR portal for WebAR using Unity WebGL build. I've seen some videos on YouTube about AR Portal tutorials but all of them was about either android or ios app. I've found this project on gitHub: https://github.com/NaelAwayes/ARFoudation-Portal, this is basically a merged version of two tutorial videos available on YouTube (PirateJustAR's tutorial: https://www.youtube.com/playlist?list=PLKIKuXdn4ZMhwJmPnYI0e7Ixv94ZFPvEP and the Unity Workbench's tut: https://www.youtube.com/watch?v=Ml2UakwRxjk&t=1534s). What would be the initial steps to get this work on webAR? I know it's not possible by default to get build on WebGL without using third party extensions.

[wanton turtle]

I use mindar and arframe for anything serious webar (not unity).

Arfoundation isn't going to help you as it doesn't work for web

I do have the mindar web arfoundation plugin, but it doesn't work with floor and plane tracking. It's for image recognition, face recognition etc. You could use it, but you'd need to use it with an image tracker.

I can't speak to the videos / tutorials, watching those is more time than I can commit. But as long as you work within the confines of the webar framework you are using, you should be able to create a portal if you want.

In this case though I'd probably use aframe.

https://aframe.io/blog/arjs3/

Alternatively yeah, image tracking through unity webar via mindar

[craggy arch]

I see, thank you for the respond @wanton turtle that means a lot!

[pallid cape]

Helloo
I'm trying to breath some life back into this project I worked on a few years ago but the face tracking SDK I used at the time has since been depracated/the company was sold. Does anyone know how I can get face tracking outside of arkit? I don't want to use a phone. The whole idea is to do face filters outside of a mobile device and have it as a webcam/desktop experience.

Basically I need a face mesh on to which I can put a material, onto which I can put a shader and attach objects (as seen in the video here:)

Hi,
I am using a tutorial to implement 'tap to place object' functionality, but I want to modify it so that users can tap anywhere on the screen and have the object appear there, not only on horizontal surfaces. The object is a floating lantern, and so it should be able to be placed in midair and not on the ground, if that makes sense. However, I'd also like to know if it is possible to track depth without needing to place the object on a horizontal surface? Ideally people could place the lanterns further back, as well as in the foreground--but I don't want them to have to spawn on the ground. The tutorial I'm following is this one: https://www.youtube.com/watch?v=pC3146FjNC0

Can someone let me know how I should modify his code in order to do what I've outlined above? Right now it's set to place an object anywhere on a horizontally tracked surface. This is the code below: And thank you so much!

`public class ARRaycastPlace : MonoBehaviour
{

public ARRaycastManager raycastManager;
public GameObject objectToPlace;

public Camera arCamera;

private List<ARRaycastHit> hits = new List<ARRaycastHit>();

void Update()
{
    Ray ray = arCamera.ScreenPointToRay(Input.mousePosition);

    if (Input.GetMouseButton(0))
    {

        if (raycastManager.Raycast(ray, hits, TrackableType.Planes))
        {
            Pose hitPose = hits[0].pose;
            Instantiate(objectToPlace, hitPose.position, hitPose.rotation);
        }
    }
}

}`

You can check out MindAR, but it may be locked to a mobile device. Outside of that, you could also use OpenCV if needed. It's a pain but works if you sink enough time into it.

[wanton turtle]

You can try changing it from .Planes to .AllTypes, but I don't think it's likely to hit a lot more. Once you click, it needs to hit something to know where to place it. Otherwise, you'll need to decide how you want it placed and just ignore the raycast completely and just place it X distance in front of you.
https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.0/api/UnityEngine.XR.ARSubsystems.TrackableType.html

Also, I'd probably move the ray into the if statement for mouse interaction, or it's going to run all the time, even when you don't need it. And I'm not sure if you meant to use .GetMouseButtonDown

Not sure if that helps or makes sense.

[merry tulip]

Does anyone know what happened? I'm new at AR and I'm using Vuforia Engine for that

[wide thunder]

Thank you!! I'm going to try .AllTypes first. I'll let you know how it goes.
On a more concerning note, I discovered that my objects are all spawning in the exact same point, no matter where on the horizontal plane I tap. It seems to be caused by the position animation keyframes on my object, as once I removed the animation the objects spawned where I tapped. It must be that the object position snaps back to the keyframe start. So if I may ask another question, how can I bypass this issue and still keep my animation on the object? Thanks!

[livid coyote]

Could someone tell me how I can get 2 buttons (at the red circled spots)? The buttons should be at the height of the plane.

[pallid cape]

Thanks @wanton turtle ! Yes opencv has been on my mind. I was also playing with keijiro's media pipe version but I struggle to understand how to get a material onto the mesh itsef. Outsie of mobile device demos, I haven't seen any examples.

[weary sundial]

Hello, I'm a unity beginner who recently completed the Essentials Pathway.
And I started the AR pathway.
But I don't have a mobile device that supports ARCore to run and test the scenes. Is there another way?

[true stag]

Does your animation clip have "apply root motion" checked? Or perhaps your animation is actually just animating the global position

[true stag]

XR simulation and XR environment can "simulate" a sample AR scene, but it doesn't have the exact same feature set and may not provide 100% accurate results to what you will experience on your phone

[wide thunder]

Thanks! That was the issue. I didn't have root checked.

[wide thunder]

How can I stop placing duplicates of the same object with a single tap, and also make sure the objects can't go inside each other? Is this something to do with collider physics? This is the 'tap to place' code I'm using. Thanks in advance!!

`public class ARRaycastPlace : MonoBehaviour
{

public ARRaycastManager raycastManager;
public GameObject objectToPlace;

public Camera arCamera;

private List<ARRaycastHit> hits = new List<ARRaycastHit>();

void Update()
{
    Ray ray = arCamera.ScreenPointToRay(Input.mousePosition);

    if (Input.GetMouseButton(0))
    {

        if (raycastManager.Raycast(ray, hits, TrackableType.Planes))
        {
            Pose hitPose = hits[0].pose;
            Instantiate(objectToPlace, hitPose.position, hitPose.rotation);
        }
    }
}

}`

[wanton turtle]

Yeah I mentioned the duplication when I saw the code yesterday... I'd change
Input.GetMouseButton(0)
To
Input.GetMouseButtonDown(0)

That way it only checks the moment you press. The current line runs as long as you are pressing.

And yeah, I'd probably do a spherecast from the touch point to see if an object already exists in its space. Or on instantiation, check if the colliders overlap

[wide thunder]

Thank you Lloyd! that seems to have done the trick. Sorry that I didn't quite catch that part earlier, I do understand now. And to answer your question, I copied this code directly from a tutorial; so nothing about it was intentional and I just didn't know how to tweak it to suit my needs. Many thanks!!

[wanton turtle]

You are doing good work and asking the right questions, no worries 🙂 it's a journey for sure!

[wide thunder]

I really appreciate that, Lloyd! Given I'm new to this, it's been a bit tough to truly understand the code; but this channel has already helped me a great deal.

If I may ask just one more question for now about the code above, how can I change it so that we take the tap to place out of the equation and just have the object appear in the scene, grounded to the horizontal plane as soon as the app launches? Another person here suggested that I raycast downward at the start to instantiate the object, but I am struggling to know what that means. I have researched this quite a bit, but I'm still lost. See, I have one object that should be 'tap to place,' and I have other objects that I want to pop up automatically with no prompting from the user. Is there a way to modify the above code for automatic instantiation?

And thank you so much for all the help you've given me!

In case anyone has issues using AR Foundation or Lightship ARDK with URP , I made a tutorial on that:

Hi I want you guys know how to build 3D modal?

[flint basin]

Depends on why you're asking

[wanton turtle]

I'm assuming you mean model? I don't think #🤯┃augmented-reality is the best place to ask - however, I strongly recommend blender, zbrush, (modo or Maya are also good). Substance, armor paint, marmoset or instamat for painting. But if you want quick and dirty you can start with the Unity add on probuilder.

[true stag]

AR Foundation 5.1.2 should be officially live, hooray!

[true stag]

I believe you were interested in hearing when the new version was released, if not I apologize for the ping!
