[Unity 4.6.1] Failed to load data set

January 29, 2015 - 12:27pm #1

Hello, I'm trying to approach object recognition through Vuforia 4 (I'm using the latest version of the open beta plugin and scanner app) and Unity 3D but I encoutered some problem and I'm not sure how to solve it.

This is what I did:
1) via the scanner app I created the .od file from the 3D object
2) I uplodaded the file to the developer portal, created an object target and downloaded the data set in Unity format
3) I imported the package into Unity, set up the scene and activated the data set in the inspector

When I hit the play button of Unity I receive the following two errors logged in the console:

=========================================================
Did not load: QCAR/TestObjects_OT.xml
UnityEngine.Debug:LogError(Object)
Vuforia.DataSetImpl:Load(String, StorageType)
Vuforia.DataSetImpl:Load(String)
Vuforia.DataSetLoadAbstractBehaviour:LoadDatasets()
Vuforia.QCARAbstractBehaviour:Start()
=========================================================
Failed to load data set TestObjects_OT.
UnityEngine.Debug:LogError(Object)
Vuforia.DataSetLoadAbstractBehaviour:LoadDatasets()
Vuforia.QCARAbstractBehaviour:Start()
=========================================================

Anyone can help, please?

Oook, new version, new issue! :P

I'm seriously starting to think I'm doing something really wrong... but I can't understand where...

Now the old error is gone but popped up a new one and here it is:

Could not associate DataSetTrackableBehaviour 'TestObjectA' - no matching Trackable found in DataSet!
UnityEngine.Debug:LogError(Object)
Vuforia.StateManagerImpl:AssociateTrackableBehavioursForDataSet(DataSet)
Vuforia.DataSetImpl:Load(String, StorageType)
Vuforia.DataSetImpl:Load(String)
Vuforia.DataSetLoadAbstractBehaviour:LoadDatasets()
Vuforia.QCARAbstractBehaviour:Start()
 
What can be the reason of this?

That  message suggests there might be some mismatch between the Target associaed to one of your Target in the Scene with the actual targets available in the Datasset (the one entered in the ARCamera inspector),

I would suggest trying the following:

- close Unity

- REMOVE the "Library" folder under your project root

- reopen your project in Unity

- check that the right Dataset is selected in the ARCamera inspector (Load Dataset XXX and Activate Dataset XXX checkboxes)

- select the Object target in your Scene

- in the target inspector, deselect and re-select the Dataset and the Target name that you want to associate to the target

You may want to try the latest 4.0 beta 11 release which went out few days ago; we tested it with the latest Unity 4.6.2 (BTW: this version also supports iOS 64bit arm64):

The following steps work for me, with 4.0 beta and Unity 4.6.2:

- Create new Unity project

- add ARCamera

- copy-paste App license key from License Manager into ARCamera license field

 - add ObjectTarget prefab to scene

- import OT Dataset (unitypackage) into scene

- select Dataset and Target in Object Target

- Load and Activate dataset in ARCamera inspector

- Run in Play Mode

Well... that's quite what I did...

I still can't figure out why keeps logging those errors.

I have the same Issue using unity 4.6.2 and even the samples, have you set the datasets within the object target? might not fix the problem cause I already did that, but maybe.
