Vuforia 8.3.8 DataSet.Load always fails

I've been using a script to load datasets on runtime from a known path (Android, iOS).

It worked fine in Unity 2018.3.0f2, but I had to update because of other errors with Unity and Vuforia that were patched on newer versions.

If I try

Code (CSharp):

1.  
2. ObjectTracker objectTracker = TrackerManager.Instance.GetTracker<ObjectTracker>();
3.  
4. if (objectTracker != null)
5. {
6.   objectTracker.Stop();
7.  
8.   if(File.Exists(dataSetXMLOutputPath)&&File.Exists(dataSetDatOutputPath))
9.   {
10.     Debug.Log("File exists");
11.     DataSet dataSet = objectTracker.CreateDataSet();
12.     if(dataSet.Load(dataSetXMLOutputPath, VuforiaUnity.StorageType.STORAGE_ABSOLUTE))
13.     {
14.       objectTracker.ActivateDataSet(dataSet);
15.     }
16.     else
17.     {
18.       Debug.Log("Could not load dataset");
19.     }
20.   }
21.   else
22.   {
23.     Debug.Log("XML and/or DAT file does not exist");
24.   }
25.  
26. }
27.  

File.Exists returns true, but dataSet.Load always fails. I've checked the files multiple times. The code just stopped working when I updated Unity and Vuforia.

These are the versions I'm developing my project on:

Unity 2018.4.3f1
Vuforia 8.3.8

Any ideas?

Thanks

 

No one? Nothing?

 

Hello,

You can find reference code for loading a dataset using Vuforia APIs in the 8.3 version of the Core Samples: /Assets/SamplesResources/SceneAssets/ModelTargets/Scripts/ModelTargetsManager.cs

The Vuforia Engine Core Samples are available for free on the Unity Asset Store.

Thanks,
Vuforia Engine Support
