Hello, I'm using Vuforia Engine 10.3 in Unity 2021.2.3f1 to process the Area Target I made with the Vuforia Creator App using an Ipad Pro Lidar.
All seemed to go well, I followed the instructions from the Vuforia website but when I select my area target in Unity it loads it but says that the Preview Prefab is not available.
Here is the detailed error:
"DllNotFoundException: VuforiaEngine.dll assembly:<unknown assembly> type:<unknown type> member:(null) Vuforia.Internal.Utility.GLTFLoading.GLTFExtractorUtility.Initialize (System.String path, UnityEngine.Material sourceMaterial, System.Boolean ignoreMaterials) (at <322f9cfa037e43d487f9bdce5f865d45>:0) Vuforia.EditorClasses.GLTFAssetCreator.Initialize (System.String filePath, System.Boolean ignoreMaterials) (at <0213e6f0fa134fa89db6bafa02899715>:0) Vuforia.EditorClasses.ExtractorUtilities.ExportAndSaveMeshAndTextureData (System.String rootFolder, System.Collections.Generic.List`1[T] glTFFiles, System.String prefabFileName) (at <0213e6f0fa134fa89db6bafa02899715>:0) UnityEngine.Debug:LogException(Exception) Vuforia.EditorClasses.ExtractorUtilit"
I'm attaching the zip of my area target scan if anybody can confirm you get the same behavior on yourr end.
Thanks,
Arnaud

I went to check the release notes and found this in the known issues:

Hey Arnaud,
Hey Arnaud,
The known GLB mesh issue seems not related to your Unity issue. I tested your area target and it seems to work fine for me.
Can you try to create a new Unity project, add Vuforia Engine, and see if the issue persists?
Hello Patrick, thanks for
Hello Patrick, thanks for your prompt answer. I did try more than 10 times so far creating new projects and always had the no prefab error message. I also tried with other area targets. What unity version are you using?

Hey there,
I'm still using Unity Engine 2020.3.22f1 and seems that Unity 2020.3.24f1 also doesn't provide the error.
You could check with those versions and see if it solves the error?
I'm sorry you're experiencing the issue.
Hey Patrick, so I gave it a
Hey Patrick, so I gave it a try with Unity 2020.3.24f1 and I was able to see the cloud point prefab of the scanned location.
Clearly there seems to be an issue related to Unity 2021 and Vuforia Engine 10.3
