Thanks for sharing the project files, Kris! This was really helpful. I managed to create my Android and iOS packages following you steps. iOS version worked perfectly as you instructed. But Android version is not working. When I launch the application on my Pixel 2, it doesn't show the placement indicator and because of that plane model is no getting added. One thing I noticed which publishing android version, I get Android SDK is outdated message (SDK build tool version 28.0.1 < 28.0.3). Did I miss any step?
That's awesome mate. Tell me something. Is it possible to export the tracked data in some way? For instance, can a point cloud or a mesh be created using the tracked data so that it may be exported as an OBJ or FBX? Thanks.
Really great tutorial. Professional quality and very easy to follow, job well done sir, congratulations. Only one addendum, they changed something in ARFoundation with the Raycast. Here are some steps to follow. 1.- Add the script to the "AR Session Origin" GameObject. All the steps that follow are in the same script you are working in during this tutorial. 2.- Add to the top: using UnityEngine.XR.ARSubsystems; 3.- Create a variable: private ARRaycastManager aRRaycastManager; 4.- In the Start Method add: aRRaycastManager = FindObjectOfType(); 5.- Instead of arOrigin use aRRaycastManager Should look like this: aRRaycastManager.Raycast(screenCenter, hits, TrackableType.Planes); That should cover it.
For everyone having problems on android with the placement indicator not showing i got it working! This is what i did: 1. To your AR Session Origin gameobject add the component "ARPlaneManager". (You do not need to provide a plane prefab unless you want to visualize the detected planes) 2. In the Tracked Pose Driver component of you AR Camera change the Update Type to "Update" (The marker will still show if you omit this step but it will be super jittery) 3. Enjoy a smooth marker! :D
Very interesting tutorial and your way of explaining is really really good ! Not too fast, not too slow, pointing out interesting details, calm voice, just perfect ! Please, continue ! :)
Being a novice in C+ scripting what would the code look like? I was able to add the component to the AR Origin GameObject, but was unable to adjust the script accordingly. Could you make the correct code accessible in some way?
@@erik_natzke Hi Erik, thanks for the quick repsonse! That worked like a charm. Could you tell me why I am now not able to add the Toy plane prefab?

I watched a couple of Unity & ARkit tutorials. This is one of the best! Very clear and most up-to-date with the tools. I just subscribed to your channel.
Thank you so much! What a great tutorial! You should put a complete course together. I would be the one to buy it. I have not seen anyone explain the coding so well. Usually they just go through it and just tell you what to write without any explanation or logic.
So glad you found it helpful and like the style, Ebrahim. I promise to make more, it's just a matter of caving out the time. Please post suggestions on any specific general or AR-specific Unity topic you're interested in seeing me cover.
@@TheUnityWorkbench Thanks! One thing that I think would be really interesting to see is how to create indoor maps also showing you on the map. Please see link for sample video: th-cam.com/video/kGkT3YKOGXU/w-d-xo.html I'm trying to figure out how the corner map is done. I haven't been able to find any tutorials.
Holy cow... I don't have a mac or an android device so I need to wait until I have access to either of those to build to a device, but this is a fantastic tutorial. I'm already proficient in unity, but I didn't feel like you were wasting any time at all. You were really easy to follow and explained everything perfectly. Thanks!
For many of you with problems, ARFoundation have evolved a lot since this video (it is in preview after all). To be able to follow this, look at 4:17 at the versions of each Package. Try to get those specific versions of the packages in the Package Manager, by clicking the arrow beside the package name and then "See all versions". Having said that, for some reason, it only worked here with AR Foundation "preview.6 - 1.1.0", which is one version above what is shown in the video. Also, if you are using Android, there is a comment by Conviley which fixes the Indicator not showing.
First of all thanks for the amazing tutorial, was really helpful. For those who were unable to see the placement indicator: 1. Device should support arcore( i have rooted redmi note 7 device which officially does not support ARcore after root everything should work fine). 2. Depending on your camera quality and lighting conditions it may take some time for indicator to appear 3. If scene is not working uncheck x86 under target architectures in player settings 4. In the new versions of AR foundation you don't need to check AR core support under XR settings Thanks again. I am planning to create AR application using Chrome browser, hopefully you can give me some tips
For everyone having issues with Unity 2019.2.0f1 and ARCore - ARFoundation 2.2.0 on Android here is a working code you will also need to add an AR Raycast Manager, an AR Plane manager with empty prefab and an AR Point Cloud manager with an empty prefab too like Conviley said in your AR Session Origin object using System; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using UnityEngine.XR.ARFoundation; using UnityEngine.XR.ARSubsystems; public class ARTapToPlaceObject : MonoBehaviour { public GameObject objectToPlace; public GameObject placementIndicator; public ARRaycastManager raycastManager; private Pose placementPose; private bool placementPoseIsValid = false;
void Start() { raycastManager = FindObjectOfType(); } void Update() { UpdatePlacementPose(); UpdatePlacementIndicator(); if (placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) { PlaceObject(); } } private void PlaceObject() { Instantiate(objectToPlace, placementPose.position, placementPose.rotation); } private void UpdatePlacementPose() { var screenCenter = Camera.main.ViewportToScreenPoint(new Vector2(0.5f, 0.5f)); var hits = new List(); raycastManager.Raycast(screenCenter, hits, TrackableType.Planes); placementPoseIsValid = hits.Count > 0; if (placementPoseIsValid) { placementPose = hits[0].pose; var cameraForward = Camera.main.transform.forward; var cameraBearing = new Vector3(cameraForward.x, 0, cameraForward.z).normalized; placementPose.rotation = Quaternion.LookRotation(cameraBearing); } } private void UpdatePlacementIndicator() { if (placementPoseIsValid) { placementIndicator.SetActive(true); placementIndicator.transform.SetPositionAndRotation(placementPose.position, placementPose.rotation); } else { placementIndicator.SetActive(false); } } } Ask me if you have issues Catzy™ #0666
Thank you so much for this tutorial. The voicing was professional and clear, which made it easy to follow. I would love to see a version of this, or a video addendum, that addresses using tracking images.
I'm just starting off with AR I'd appreciate any help i can get. I deployed the app to my iPhone from Xcode but all i get is a black screen. How can i fix that?
Thanks for the tutorial! I'm following without any errors up until 09:00. After that it stops - I can't launch the first iOS build on my iPhone 7. When I try to run the iOS build from Xcode, I'm getting 76 error messages about "undefined symbols". Any ideas on what might be causing these issues?
I had the same problem and found a fix for me, it was because at the package manager in min 4:11 I installed the updated ARFoundation-Arkit-ARcore 2.0 versions, the correct versions are the 1.0 versions, if you see closely the moment he installs in the video and pause youll see the correct versions.. same answer here => forum.unity.com/threads/error-when-building-samplescene-from-arfoundation-to-iphone-6s.545338/#post-4629886
For Unity 2019.1.4 with try this: Instead of: arOrigin.Raycast(screenCenter, hits, TrackableType.Planes); use the new raycast manager (add the ARRaycastManager component to the AR Session Origin Game Object first) public ARRaycastManager raycastManager; raycastManager.Raycast(screenCenter, hits, TrackableType.All);
if you get the error "The name 'TrackableType' does not exist in the current context", add using UnityEngine.XR.ARSubsystems; at the top of your code will fix it
Have a problem getting the Raycasting. The compiling does not occur and throws up this error. Any help is appreciated :) .Error CS1061: 'ARSessionOrigin' does not contain a definition for 'Raycast' and no accessible extension method 'Raycast' accepting a first argument of type 'ARSessionOrigin' could be found (are you missing a using directive or an assembly reference?)

a complete black screen on android.........even on the cube test the app is not even prompting for camera permission..... please help its been 2 days i am stuck
One question, so the ARKit XR package features used in your scene are basically ARKit Plugin (from bitbucket) features? Or is there a difference in terms of camera scripts, plane detection and so on?
Thank you for the tutorial! It's really well done! I'm having an issue that I can't seem to resolve. I was able to do the first test and make the Cube appear so clearly something is working. When I go to the next step (placement indicator and plane detection), the build is successful, the app starts and the camera feed works as well but no placement indicator shows up. The one thing I know is that the version I'm using is not the same than in this video which may have caused a few updates (such as the ARRaycastManager not being part of ARSessionOrigin anymore). I use Unity 2019.2.13f1 and ARFoundation 2.0.2 and my phone is a Nexus 5X with Nougat installed on it. I'm pasting the code below to see if anyone can find what I'm doing wrong. Thank you for you help!! using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.XR.ARFoundation; using UnityEngine.Experimental.XR; using System; using UnityEngine.XR.ARSubsystems; public class ARTapToPlaceObject : MonoBehaviour { public GameObject placementIndicator;
Update: I switched to AR Foundation 3 (not sure that it helped but it's still something I did), added the ARPlaneManager as it was suggested by Conviley below. That's when I started seeing something (the placement indicator). The final fix was that for the vector3 I'm giving to ViewportToScreenPoint I had to do 0.5f,0.5f,0 (vs 0.5f,0,0.5f). I think this fixed it. I hope it helpes anyone else!
Hi Kris, I was able to follow and successfully complete your tutorial. My question is how do I put only one airplane on the plane and then pinch-and-zoom to see the airplane bigger. Thanks!
Henry, if you look through the comments you’ll see my suggestions for how to limit placement to a single object. As for the additional functionality to resize the object interactively, others have suggested that as well so I’ll be sure to consider that for a future tutorial!
Here's the full answer for easy access... Limiting to placing a single object is not too difficult. Here's one approach... Add a new property at the top of the script to track whether the user has placed an object, and initially set it to false... private bool placementIsComplete = false; Then, in the PlaceObject() method add this line... placementIsComplete = true; Finally, in the UpdatePlacementIndicator() method, change the first line of the "if" statement to this... if (!placementIsComplete && placementPoseIsValid) This isn't necessarily the most efficient approach but it's the easiest to describe adequately in a comment. :) I hope this helps!
The quality of this video and your explanation are really top level, if you have an online course or any pay material, please let me know because you have buyer on me!

Even if copy pasted the entire code, I am getting the error for "Raycast" in the line arOrigin.Raycast(screenCenter, hits, TrackableType.Planes); Please help!!!!!
The way to do this has been updated, try adding ARRaycastManager component your arOrigin and then use this instead arOrigin.GetComponent().Raycast(screenCenter, hits,UnityEngine.XR.ARSubsystems.TrackableType.Planes);
Thanks! what a great tutorial! perfect! I really liked the way you walk us through the code with the level of details you choose to talk about... and it also very clear that the force is strong with you!... please do more!, especially for ARFoundation... this thing is creasy new and should have much more information about it.
Thanks for the positive feedback, Ariel! I've already got the next ARFoundation video planned and started. If you have specific questions, techniques, or challenges you'd like to see covered LMK.
Setting up the Android Environment was basically too hard for Unity 2018.3. There's basically no information available on this topic and I ran into some headaches, reading forum threads and docs. I wasted an entire before I discovered I might be able to just build this app alongside your tut in newer version of Unity. Wish me luck! Aloha
Sorry for the lack of respect from me. I did the tutorial and I did not use the like button to help more people to reach this good video. Thanks for sharing your knowledge
I followed til 09:14 and I am using android device. The app opens but It never shows the cube. It asked for camera permission too, i gave it but I can't see the cube
In android,the placement indicator is being shown at the start,but it just stays there and does not move along with the camera. any idea why ? And also the cube is not being placed on the click.
Hi, thanks you for the tutorial but i have a several issue, when I install the plugins, I add the AR Session and the AR Session Origin but the screen is in black and it looks like the shader doesn't work properly, does anyone know how to solve it? Thanks you!
Hi, I did all the steps of the tutorial. When I run the app on the android mobile to show the cube this works fine, but when I continue with the tutorial making the changes to show the Placement Indicator, when running the app the Placement Indicator is not visible on any surface. I am using Windows 10, Unity 2018.1.7 and ARCore.
Luis, I'll look into this when I can find some time. It might be a couple weeks, though (sorry!). Can you try this with 2018.3 and see if you get different results? (That's the version I used for the tutorial.)
appear same problem too.... so i try to solve this problem to revise 'TrackableType.plane -> TrackableType.FeaturePoint'. this solution is a temporary measure. this link show how to operate th-cam.com/video/cuWEoh7PFTQ/w-d-xo.html i am using widows10, unity 2018.3 and ARcore
If you add the ARPlaneManager component to the AR Session Origin gameobject the marker will appear. However, it does not perform as smooth as in the video and i'm not sure why. According to the scripting API: "When [ARPlaneManager component is] enabled, this component subscribes to planeAdded, planeUpdated, and planeRemoved. If this component is disabled, and there are no other subscribers to those events, plane detection will be disabled on the device." So it seems like you have to have the ARPlaneManager or at least something else subscribing to those events to get plane detection to enable. using Unity 2018.3.3f1
I got it working! This is what i did: 1. To your AR Session Origin gameobject add the component "ARPlaneManager". (You do not need to provide a plane prefab unless you want to visualize the detected planes) 2. In the Tracked Pose Driver component of you AR Camera change the Update Type to "Update" (The marker will still show if you omit this step but it will be super jittrey) 3. Enjoy a smooth marker! :D
I would like to thank you for this tutorial. I find it very helpful. Unfortunately, under the new builds ARFoundation is different with respect to the AR Session Origin. This is something I need to learn to take this fine tutorial and adjust it to the new build(s). I have tried to go back to the version you use, but I encounter a number of build errors. Regardless; thank you for this tutorial. I enjoy your teaching style as it resonate well with me.
Immediately, when I add this code i get an error. var cameraForward = cameraForward.current.transform.forward; var cameraBearing = new Vector3(cameraForward.x, 0, cameraForward.z).normalized; placementPose.rotation = Quaternion.LookRotation(cameraBearing); When I erase it code builds just fine
Your tutorial was very helpful, but my device (iPhone 12 mini, ios15) doesn't ask me for permission for camera access so I can only see a black background and the cube. what can I do? I can't find any helpful tips. thank u!
not working anymore. i use the latest unity 2019.3.3 and xcode 11 follow all your steps. and tried to load the cube in arkit. my app just crashed all the time. by the way it's iphone xr with ios 13.3.1 running. i promise i follow all the steps with no faults but the app still crash all the time.
Hi Kris, How do I access the arplanemanager.enabled to temporary hide the plane indicator? This way I can walk around to see the model without the appearance distraction of the arrow. By the way, I was able to follow your tutorial and create a working ARFoundation app on iPhone :) Thanks.
Henry, you don't have to access arplanemanager to accomplish what you describe. Just set the visibility of the placement indicator game object to false at the same time you add the prefab instance. LMK if that isn't enough detail.
Hi there, I am having trouble in building this project on my android device. During the first stage on displaying the cube, the build was successful and the app runs automatically on my phone but after the welcome to Unity screen the AR camera won't start, it's just all black. Anyone who might know the problem? I follow all from the tutorials and I encounter no problems during the build process. Any help to clarify the issue will help. Thank you
Thank you very much for your tutorial. I have followed tutorial, and try with iOS is work well, but when I try to increasing the size of 3D model and placement indicator, it faced some problem: . Does it possible to recognize the floor, if I want to placement with big 3D object ( around 3 meter x 1.5 meter )? . When I touched the screen, it always added new 3D object. Is it possible, if I want to add 3D object only one on first touching screen? and then, can disable or enable (buttons) plane detection and still appear 3D object that have added to interact on 3D object. . After added one 3D object, How can we make interaction on 3D object? such as, rotation or scale. Could you make tutorial for solving above issues? Thank you very much.

All the steps that follow are in the same script you are working in during this tutorial.
2.- Add to the top:
using UnityEngine.XR.ARSubsystems;
3.- Create a variable:
private ARRaycastManager aRRaycastManager;
4.- In the Start Method add:
aRRaycastManager = FindObjectOfType();
5.- Instead of arOrigin use aRRaycastManager
Should look like this:
aRRaycastManager.Raycast(screenCenter, hits, TrackableType.Planes);
That should cover it.

@@TheUnityWorkbench Thanks! One thing that I think would be really interesting to see is how to create indoor maps also showing you on the map. Please see link for sample video: th-cam.com/video/kGkT3YKOGXU/w-d-xo.html
I'm trying to figure out how the corner map is done. I haven't been able to find any tutorials.
This was really excellent. Not only in content, but also in production quality. I can see you put a ton of time to make it so clear. Thank you.
Holy cow... I don't have a mac or an android device so I need to wait until I have access to either of those to build to a device, but this is a fantastic tutorial. I'm already proficient in unity, but I didn't feel like you were wasting any time at all. You were really easy to follow and explained everything perfectly. Thanks!
For many of you with problems, ARFoundation have evolved a lot since this video (it is in preview after all). To be able to follow this, look at 4:17 at the versions of each Package. Try to get those specific versions of the packages in the Package Manager, by clicking the arrow beside the package name and then "See all versions". Having said that, for some reason, it only worked here with AR Foundation "preview.6 - 1.1.0", which is one version above what is shown in the video. Also, if you are using Android, there is a comment by Conviley which fixes the Indicator not showing.
Thank you so much i was about to kill myself
First of all thanks for the amazing tutorial, was really helpful. For those who were unable to see the placement indicator:
1. Device should support arcore( i have rooted redmi note 7 device which officially does not support ARcore after root everything should work fine).
2. Depending on your camera quality and lighting conditions it may take some time for indicator to appear
3. If scene is not working uncheck x86 under target architectures in player settings
4. In the new versions of AR foundation you don't need to check AR core support under XR settings
Thanks again. I am planning to create AR application using Chrome browser, hopefully you can give me some tips
Best Explained tutorial I ever saw on any AR related topic. Cheers !!
Make part 2! Very good tutorial for people that have to make application on ios + android at same time!
At the 4:40 mark, if you don't see XR in the menu options, quit Unity and open it back up. XR should now be in the menu.
Amazing, explained it very good, knows how to speak English and shows how to do everything, that earned my sub.
Brilliant stuff and so well explained. Not many people have the knack of explaining things well enough but you do....👍
Very good tutorial for ARFoundation, especially for beginners. Please continue create content on ARFoundation and keep up the good work!
For everyone having issues with Unity 2019.2.0f1 and ARCore - ARFoundation 2.2.0 on Android here is a working code

Placement Indicator is unfortunately still staying in place for me. Using 2019.2 latest versions.
When it runs it seems to take a long time recognizing the floor. I'm still placing cubes but they are in mid-air and not on the floor.
Thanks a lot! Clear explanation. Can't wait for your new tutorials.
Great explanation!
I would like many more tutorials from Unity Workbench
Thank you so much for this tutorial. The voicing was professional and clear, which made it easy to follow. I would love to see a version of this, or a video addendum, that addresses using tracking images.
Wow I just learned mobile and AR with this video was struggling with the settings, thanks for the detailed and to the point veio. ENJOYED IT
I'm just starting off with AR I'd appreciate any help i can get. I deployed the app to my iPhone from Xcode but all i get is a black screen. How can i fix that?
How to Update 'Raycast' in this line of code to AR Foundation New version?
arOrigin.Raycast(screenCenter, hits, TrackableType.Planes);
Thanks for the tutorial!
I'm following without any errors up until 09:00. After that it stops - I can't launch the first iOS build on my iPhone 7. When I try to run the iOS build from Xcode, I'm getting 76 error messages about "undefined symbols". Any ideas on what might be causing these issues?
I had the same problem and found a fix for me, it was because at the package manager in min 4:11 I installed the updated ARFoundation-Arkit-ARcore 2.0 versions, the correct versions are the 1.0 versions, if you see closely the moment he installs in the video and pause youll see the correct versions.. same answer here => forum.unity.com/threads/error-when-building-samplescene-from-arfoundation-to-iphone-6s.545338/#post-4629886
Thanks for the great tutorial! Please do more. I have never seen as good explanation as yours. It helped me a lot in my project.
For Unity 2019.1.4 with try this:
Instead of:
arOrigin.Raycast(screenCenter, hits, TrackableType.Planes);
use the new raycast manager (add the ARRaycastManager component to the AR Session Origin Game Object first)
public ARRaycastManager raycastManager;
raycastManager.Raycast(screenCenter, hits, TrackableType.All);
if you get the error "The name 'TrackableType' does not exist in the current context", add using UnityEngine.XR.ARSubsystems; at the top of your code will fix it
Fantastic!
Finally a great ARFoundation tutorial.
Even I could follow along.
Have a problem getting the Raycasting. The compiling does not occur and throws up this error. Any help is appreciated :) .Error CS1061: 'ARSessionOrigin' does not contain a definition for 'Raycast' and no accessible extension method 'Raycast' accepting a first argument of type 'ARSessionOrigin' could be found (are you missing a using directive or an assembly reference?)

for those ios user who encounter the problem of camera not opening. try to add the audio listener component into the AR Session origin camera.
ARSessionOrigin is not exposing the Raycast method anymore. What should we use instead?
same problem.
Use ARRaycastManager instead of ARSessionOrigin

Very useful, well thought out and organised tutorial. Really appreciate the upload sir. Thank you.
Edit: Why aren't you uploading anymore?
This tutorial was EXCELLENT! Thank you so much The Unity Workbench!
Thanks for the shadow tip. So useful.
One question, so the ARKit XR package features used in your scene are basically ARKit Plugin (from bitbucket) features? Or is there a difference in terms of camera scripts, plane detection and so on?
Thank you for the tutorial! It's really well done! I'm having an issue that I can't seem to resolve. I was able to do the first test and make the Cube appear so clearly something is working. When I go to the next step (placement indicator and plane detection), the build is successful, the app starts and the camera feed works as well but no placement indicator shows up. The one thing I know is that the version I'm using is not the same than in this video which may have caused a few updates (such as the ARRaycastManager not being part of ARSessionOrigin anymore). I use Unity 2019.2.13f1 and ARFoundation 2.0.2 and my phone is a Nexus 5X with Nougat installed on it. I'm pasting the code below to see if anyone can find what I'm doing wrong. Thank you for you help!!

}
}
}
Update: I switched to AR Foundation 3 (not sure that it helped but it's still something I did), added the ARPlaneManager as it was suggested by Conviley below. That's when I started seeing something (the placement indicator). The final fix was that for the vector3 I'm giving to ViewportToScreenPoint I had to do 0.5f,0.5f,0 (vs 0.5f,0,0.5f). I think this fixed it. I hope it helpes anyone else!
The Unity Workbech the imported asset placement indicator on transparent quad, is made in image design editor, saved in ".png", I'll try it right away
I still missing the arOrigin.Raycast and TrackableType.Planes, need help! all 3 plugins are installed
Hi Kris,
I was able to follow and successfully complete your tutorial.
My question is how do I put only one airplane on the plane and then pinch-and-zoom to see the airplane bigger.
Thanks!
Henry, if you look through the comments you’ll see my suggestions for how to limit placement to a single object. As for the additional functionality to resize the object interactively, others have suggested that as well so I’ll be sure to consider that for a future tutorial!
Here's the full answer for easy access...
Limiting to placing a single object is not too difficult. Here's one approach...
Add a new property at the top of the script to track whether the user has placed an object, and initially set it to false...
private bool placementIsComplete = false;
Then, in the PlaceObject() method add this line...
placementIsComplete = true;
Finally, in the UpdatePlacementIndicator() method, change the first line of the "if" statement to this...
if (!placementIsComplete && placementPoseIsValid)
This isn't necessarily the most efficient approach but it's the easiest to describe adequately in a comment. :) I hope this helps!
That was a better tutorial than anything I've seen for ARKit. Thanks so much
Please make it as a series.

Dark mode is our friend...
I followed til 09:14 and I am using android device. The app opens but It never shows the cube. It asked for camera permission too, i gave it but I can't see the cube
Having the same issue!
In android,the placement indicator is being shown at the start,but it just stays there and does not move along with the camera. any idea why ?
And also the cube is not being placed on the click.
I have the same issue so if someone could help with this it would be greatly appreciated
Add or require an ar raycast manager to the arr session origin if you are using unity 2019.2
And also a plane manager i think in the ar session origin

Hi, thanks you for the tutorial but i have a several issue, when I install the plugins, I add the AR Session and the AR Session Origin but the screen is in black and it looks like the shader doesn't work properly, does anyone know how to solve it?
Thanks you!
Hi, I did all the steps of the tutorial. When I run the app on the android mobile to show the cube this works fine, but when I continue with the tutorial making the changes to show the Placement Indicator, when running the app the Placement Indicator is not visible on any surface. I am using Windows 10, Unity 2018.1.7 and ARCore.
Luis, I'll look into this when I can find some time. It might be a couple weeks, though (sorry!). Can you try this with 2018.3 and see if you get different results? (That's the version I used for the tutorial.)
@@TheUnityWorkbench hi, i have the same problem with unity 2018.3
appear same problem too.... so i try to solve this problem to revise 'TrackableType.plane -> TrackableType.FeaturePoint'. this solution is a temporary measure. this link show how to operate th-cam.com/video/cuWEoh7PFTQ/w-d-xo.html
i am using widows10, unity 2018.3 and ARcore
If you add the ARPlaneManager component to the AR Session Origin gameobject the marker will appear. However, it does not perform as smooth as in the video and i'm not sure why. According to the scripting API: "When [ARPlaneManager component is] enabled, this component subscribes to planeAdded, planeUpdated, and planeRemoved. If this component is disabled, and there are no other subscribers to those events, plane detection will be disabled on the device." So it seems like you have to have the ARPlaneManager or at least something else subscribing to those events to get plane detection to enable.
using Unity 2018.3.3f1
I got it working! This is what i did:
1. To your AR Session Origin gameobject add the component "ARPlaneManager". (You do not need to provide a plane prefab unless you want to visualize the detected planes)
2. In the Tracked Pose Driver component of you AR Camera change the Update Type to "Update" (The marker will still show if you omit this step but it will be super jittrey)
3. Enjoy a smooth marker! :D
Great tutorial, thank you so much! Please, consider make some more of this :)

How to Update 'Raycast' in this line of code to AR Foundation New version?
arOrigin.Raycast(screenCenter, hits, TrackableType.Planes);
In visual studio code, the functions and methods linked with unity don't autocomplete. What should be done for the cut completion to work properly?
Anyone else have the problem that the model instantiates to air? Not on the surface? How to fix this?
I would like to thank you for this tutorial. I find it very helpful. Unfortunately, under the new builds ARFoundation is different with respect to the AR Session Origin. This is something I need to learn to take this fine tutorial and adjust it to the new build(s). I have tried to go back to the version you use, but I encounter a number of build errors.
Regardless; thank you for this tutorial. I enjoy your teaching style as it resonate well with me.
Immediately, when I add this code i get an error. var cameraForward = cameraForward.current.transform.forward;
var cameraBearing = new Vector3(cameraForward.x, 0, cameraForward.z).normalized;
placementPose.rotation = Quaternion.LookRotation(cameraBearing); When I erase it code builds just fine
amazing tutorial.. thanks a lot.would be really cool to see some UI tutorials in the future.
Your tutorial was very helpful, but my device (iPhone 12 mini, ios15) doesn't ask me for permission for camera access so I can only see a black background and the cube. what can I do? I can't find any helpful tips. thank u!

Hi Kris,
How do I access the arplanemanager.enabled to temporary hide the plane indicator? This way I can walk around to see the model without the appearance distraction of the arrow. By the way, I was able to follow your tutorial and create a working ARFoundation app on iPhone :)
Thanks.
Henry, you don't have to access arplanemanager to accomplish what you describe. Just set the visibility of the placement indicator game object to false at the same time you add the prefab instance. LMK if that isn't enough detail.

Thank you very much for your tutorial.
I have followed tutorial, and try with iOS is work well, but when I try to increasing the size of 3D model and placement indicator, it faced some problem:
. Does it possible to recognize the floor, if I want to placement with big 3D object ( around 3 meter x 1.5 meter )?
. When I touched the screen, it always added new 3D object. Is it possible, if I want to add 3D object only one on first touching screen? and then, can disable or enable (buttons) plane detection and still appear 3D object that have added to interact on 3D object.
. After added one 3D object, How can we make interaction on 3D object? such as, rotation or scale.
Could you make tutorial for solving above issues?
