Hi,

I believe the issue there are 2 issues both of them related to the old VE version beind used.

For 2019.4 we recommend at least 9.4. here is more on the supported versions: info: https://library.vuforia.com/platform-support/supported-versions.html

Please upgrade to our latest version as you used the latest Vuforia scanner app version.

How to install our latest VE version:  https://library.vuforia.com/articles/Solution/vuforia-engine-package-hosting-for-unity.html

Thank you.

Hi, 

Any solution to that issue?

The example are working fine for me, also are my old database with scanned object. I have downloaded the Vuforia Scanner App on my S7 today, and it seems to scan my object well. The Scan test run fine, and it seems that I can build up a conventional object database on the developer portal. 

Now, when I import my database into unity (I am using Unity 2019.4.10 and Vuforia 8.1.12 which is the one recommended for that version of unity in the package manager) and use Object Tracker, I have the following error:

Could not associate DataSetTrackableBehaviour 'babypotatoe' - no matching Trackable found in DataSet!

UnityEngine.Debug:LogError(Object)

Vuforia.StateManager:AssociateTrackableBehavioursForDataSet(DataSet)

Vuforia.DataSet:Load(String, StorageType)

Vuforia.DataSet:Load(String)

Vuforia.DatabaseLoadARController:LoadDatasets()

Vuforia.VuforiaARController:StartAfterInitializationCompleted()

Vuforia.VuforiaARController:UpdateState(Boolean, Boolean)

Vuforia.DigitalEyewearARController:Update()

System.Delegate:DynamicInvoke(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

Vuforia.DelegateHelper:InvokeWithExceptionHandling(Action)

Vuforia.VuforiaBehaviour:Update()

I have not been able to find anything that solved this issue. I would appreciate if you guys could have a look at it. See my package attached.

Did someone had a solution for this? I'm getting the same error. Can't use any user defined 3d scans to perform object recognition on my game.

I'm currently using Unity 2019.2 + Vuforia 8.5.9

Hello, I am getting this error with the user defined option

Unity 2018.3.11f1 + Vuforia 8.1.7

I happens in play mode

However even with a predefined target image I am getting an error too in play mode.

NullReferenceException: Object reference not set to an instance of an object

Vuforia.EditorClasses.WorkerToMainScheduler.UpdateFromMainThread () (at <f16efb4dbc12426aabe71918aeadff8b>:0)

UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/Editor/Mono/EditorApplication.cs:200)

I just updated my Vuforia yesterday, it was working for the predefined target before

Thanks

p.s. actually I opened another project and the predefined is still working there, so cant be the update I guess

I have the same problem here!.. could you find a solution for this? I'm using Unity 2018.2.2f1

Hello overbytestudio,

Which version of Unity + Vuforia are you using? Is this happening when you change the value and playmode is not running? Or is this happening after you've changed it and you are running the app in playmode/on device? Do you see this behaviour in the samples?

Thanks,

Vuforia Support
