Official ARFoundation v3.0

@mistergreen2016 If you want to use ARCore Cloud Anchors with ARFoundation then add the following package:

https://codelabs.developers.google.com/codelabs/arcore-extensions-cloud-anchors/#0

It should work cross platform with iOS and Android (have only tested this package with Android myself though).

 

We recommend Google's AR Foundation extension package if you are interested in using ARCore Cloud anchors: https://developers.google.com/ar/develop/unity-arf

 

Cool, I wasn't sure if ARCore Cloud anchor was iOS compatible.

 

hallo,
we trying to Work with CollaborationData,
The ARCollaborationDataExample scene works just fine.
the transform of the shown object is sent, so is
there a way to add more data or just a variable to it.
.

 

Tried this, doesn't work with -preview.1, you can't populate the Reference Object Assets and get a build error of either missing the reference or import error "Input string was not in the correct format"

 

Actual log:

Hello. Does adding an ARPointCloudManager in my scene will improve the tracking of an ARAnchor ?

 

How can we include AR Foundation 3.0.1, but still target a build for iOS 10.0? I want AR functionality on devices that support ARKit, and will offer up alternate content for older devices. The docs say that we can set the ARKitSettings to Optional, to support all devices. (https://docs.unity3d.com/Packages/com.unity.xr.arkit@3.0/manual/index.html#build-settings)

However, I receive this error when setting the Target Minimum iOS Version to 10.0:

BuildFailedException: You have selected a minimum target iOS version of 10.0.0 and have the ARKit package installed. ARKit requires at least iOS version 11.0 (See Player Settings > Other Settings > Target minimum iOS Version).

Using Unity 2019.2.9 w/ AR Foundation 3.0.1

Any thoughts?

 

You can't get around this.

 

I have used ARKit within an iOS app in the past that targeted iOS 10, but without AR Foundation. It was just the direct AR Kit plugin. I just detected if it was supported or not, and then loaded the appropriate scene.

Hoping there is a similar way with AR Foundation. The docs that I referenced above appears to indicate there is a way.

 

Does anyone know what version of AR Foundation / ARKit stopped allowing the ability to publish to iOS 10?

[UPDATE] It appears that it will publish to older iOS version if using ARFoundation version 2.0.2, which is Unity 2019.2 Verified.

 

Unity 2019.2.9 does successfully build to iOS10 using ARFoundation 2.0.2. However XCode fails when building to device with the error...

Unable to install. Requires the "arkit" capability which is not supported by [PHONE_NAME]

Shouldn't we be able to build to lower end devices and then do our own AR detection and serve up the appropriate scene if unsupported.

 

This says it. Some ARKit function can't be supported on iOS 10.

 

Hi I build an App with both Ground Tracking and Face Tracking and made a button which switches between them. The Problem is with the performance the Ground tracking which works on Rear camera gives 30 fps where as when i am using Face Tracking which uses Front Camera the fps drops to 20 fps which gives a lot of lag. Can you please help how should i increase the fps of the front camera face tracking.

 

I found the solution on building to an iOS version that is below 11.0 while still including ARFoundation/ARKit. You must create an ARKitSetting asset and set the Requirement to Optional.

https://docs.unity3d.com/Packages/com.unity.xr.arkit@2.0/manual/index.html#using-arkit-xr-plugin

 

sure you can do that. It doesn't mean ARkit will work on iOS 10.

Code (CSharp):

1. If ARKit is set to optional, the app may be installed on a device that does not support ARKit.

 

Yep, correct. I will serve up alternate content on those lower end devices.

 

Oh, you should have said that to begin with.

 

I did above.

 

Is Object tracking still an iOS only thing? The current documentation is confusing with the example projects on github saying the example requires iOS, but the manual seemingly implying that the functionality should work overall.

 

ARCore does not seem to support this at this time so it will not work on android.

 

Hello,
I am upgrading my app from an old version of ARFoundation.

I got an error when I tried to build Asset Bundles using the Asset Bundle Browser. I can make a build and export it to iOS, but I need to be able to build Asset Bundles as before.

The log is:

Code (log):

1. Plugin 'UnityARKit.a' is used from several locations:
2. Packages/com.unity.xr.arkit/Runtime/iOS/Xcode1100/UnityARKit.a would be copied to <PluginPath>/UnityARKit.a
3. Packages/com.unity.xr.arkit/Runtime/iOS/Xcode1000/UnityARKit.a would be copied to <PluginPath>/UnityARKit.a
4. Please fix plugin settings and try again.

How can I delete the Xcode1000 plugin?

I am using ARKit XR Plugin version 3.0.1, and Unity 2019.3.4f.

 

I also ran into the "Plugin 'UnityARKit.a' is used from several locations" issue today.

The ARKitBuildProcessor in the com.unity.xr.arkit package is responsible for selecting the proper version but it is wrapped in

#if UNITY_IOS

, which is a bad idea for editor code.

The reason is that UNITY_IOS is set based on the active build target but editor code does not get recompiled if you compile for another build target via

BuildPipeline.BuildPlayer

.

i.e. if your active build target is Android and you start an iOS build using

BuildPipeline.BuildPlayer

, then all editor code that is wrapped in

#if UNITY_IOS

will not be executed!

The quickest workaround is to make sure your active build target is iOS before doing an iOS build.

However, it would be better for Unity to switch to a dynamic build target check that does not rely on

#if UNITY_IOS

, or at least implement a check that errors out in that case.

 

@tdmowrer @todds_unity
I wanted the same thing as the OP : get Session pointer from Unity and pass it on to a Java/Kotlin library. The docs referenced would give me a void* pointer to session - how do I use that from the Java/Kotlin side of things? If there is an example repo out there, would love to get a link. @amichai2 did you get this working?

thx

 

You can use native pointers with the native APIs on the respective platforms. See ARCore API and ARKit API.

 

Hi @steego, we are encountering the same errors after upgrading from ARFoundation 2 to 3. Did you found any solution?

 

Not really no, the errors didn't impact any functionality for me, so I just ignored them.

 

ARCore is now in 1.16 for Unity. Can we use it within ARFoundation ?
Can I download ARCore 1.16 and upgrade my ARFoundation ? (because ARFoundation use 1.12)

 

Does ARFoundation Team has an issue tracker ? Like a Github issue page ?

I want to add this suggestion :
When using ARCore ImageLibrary it gives us a "score" of the picture :


But in ARFoundation it does not give the "score". I would love to see the score in ARFoundation !

 

I have a couple of issues when building to iOS.
Using Unity 2019.3.7f1, all ARFoundation packages at 4.0.0 preview 1, but experienced error with earlier packages too.

First, it crashes on launch, because it's lacking an image tracking library(and object tracking):
InvalidOperationException: Cannot start image tracking without an image library.

We aren't using any library atm. and would love to be able to build without going into the ARLoader-script and commenting out everything related to ImageTracking/ObjectTracking

Another issue I get, blocking the build in Unity is the ARKitLWRPBackground, not finding LWRP, since we are using URP. Can be solved by having both URP and LWRP in project, or replacing the "LWRP"-bit in the shader with "Universal", but thats messy!

 

Problem with imagetracking still happens, even with an imagetracking library set to the correct component, or when i don't have the component at all, really annoying!

 

Brother Is it possible to put our 3D Object (Human) binding on The Terrain in AR mode.? I mean when i shoot the Image Target with my android phone then it wil show me the model (3D Human) stand on The Terrain ...

 

Hello,

I am using Unity 2019.3.5f1 + URP 7.2.0 + ARFoundation 3.0.0 for an AR project on Android/iOS.

I am using PostProcessing for some 3D objects, and I want the postprocessing not affecting the camera feed from ARFoundation. How would I accomplish that?
Suggestions here didn't resulted to me: https://forum.unity.com/threads/urp...essing-exclude-the-arcamerabackground.811254/

I see we could do something similar to this (https://github.com/Unity-Technologies/UniversalRenderingExamples/wiki/3D-Skybox), rendering cameras in the anti natural order. But would that work with the ARFoundation's ARBackground RendererFeature?
It seems it doesnt work, in mobiles ARBackground renderer feature (in Overlay Camera) renders everything and overwrites the result of Base camera (no matter what the Stencil Buffer has).

Thanks!
Pablo

 

Post processing slows down the frame rate of AR, especially when it's set to post process 'global'. You'll have to use by 'volume'.

 

Yeah.. we are using Volume

 

AR Foundation 3.1.0 preview version implemented ARKit3 related features such as HumanBodySubsystem and OcclusionSubsystem, but in 3.1.3 all those features have been removed! why? Those seems that in the preview version of 4.0.0 is back again.
Nothing is written about this in the ChangeLog either. I am confused. I need explanation.

We have already released an app that implements people occlusion. What should we do? Should we continue to use the preview version of 3.1.0? Should we move to the 4.0.0 preview version? Is there a possibility that these features will be removed in the future?

 

Hello.
AR Foundation 3.0.1 documentation says

But when, in the hierarchy, I do Right Click => XR=> Session Origin
It add a ARSessionOrigin GameObject with a Camera with a ARPoseDriver. Not a TrackedPoseDriver. Should I remove the ARPoseDriver and add the TrackedPoseDriver ? Or should the documentation be updated ?

 

ARPoseDriver is a recent component to replace TrackedPoseDriver for AR. TrackedPoseDriver is a generic driver for AR & VR.

 

This is an unfortunate artifact of our internal package publishing processes between verified and preview packages.

ARHumanBodyManager and AROcclusionManager exist in the latest 4.0.0-preview.3 packages, and we are working to include them in the forthcoming 4.0.x verified packages.

 

Thank you for your reply. It would have been nice if such information was included in the Change log.

 

Hi,

Which version of ArFoundation and ArKit compatible with Unity 2019.4LTS and Xcode 11.5

I tried these combos:
1. ARFoundation 2.1.8 + ArKit 2.1.9, result: black screen on iOS device (ver 13.3.1)
2. ARFoundation 3.1.3 + ARKit 2.1.9, result: lot of error in Unity Editor
3. ARFoundation 3.1.3 + ARKit 3.1.3, result: black screen on iOS device (ver 13.3.1)

Camera usage description is set.

thank in advance

RESOLVED! the problem was I missed URP settings: https://forum.unity.com/threads/con...-0-0-preview-to-work-with-lwrp-or-urp.736583/

 

Hi,

I am trying to change the prefab referenced in Face Prefab (or update its materials) on AR Face Manager at runtime. (AR Foundation 4.1.0 Preview 6). The only way I've managed to make this work is to set the AR Session Origin game object to false and then set it back to true. This works but it's bit naff as a user experience, as the screen goes black for about 1 sec as the session restarts. Anyone know more elegant approach to this?

Thanks in advance
KeithT

 

Ok this is incredibly frustrating!

I have black screen issue.

Started with URP template.

Can someone _please_ help? I've spent hours today trying this on multiple platform combinations. What the hell is going on? Why is this such a PITA. This is the type of configuration sphaghetti that really makes me hate Unity's approach. Please help me learn to love Unity.

Any suggestions?

 

Please pass the reference to URP here:

 

Good catch. I just did this and made a new build, but it still seems to show black. I'm removing the app and doing a new build now. Lets hope it fixes it.

P.S. Ive been eyeing your toolset today. Likely you'll have another customer (I develop on a windows machine mainly and have to built on xcode).

 

Hey Kiril. Still having this issue. Still black. I've set the rendering pipeline in both Quality -> Rendering and Graphics -> Scriptable Render Pipeline Settings

 

Please make sure that you've assigned the URP reference to the Quality settings that are default for your target platform.

 

Ahah! That was the issue. Damn. So many gotcha's with Unity compared to Unreal.

Thank you so much Kirill!

 

Hello. Did you manage to solve this ?
