No model or meshes

October 15, 2018 - 5:15am #1

Hello,

I have a problem with the model target prefab of my object.

I have a .fbx of sunglasses and use it on the model target generator. I then import the unity package (and it says "Json node is null"). I configure vuforia with the licence and all but when i create the modelTarget, the model is not in the editor or default preview. Moreover, in the associate file (in models) there is an empty prefab and an empty file meshes.

I don't understand why the model is not created.

Best regards.

Hello @sitagy,

Many issues related to Model Targets device databases failing to load are license related. Classic and Cloud licenses are not valid for the Model Targets feature.

To test this, I suggest you create, download and integrate a Developer license into your project to see if this resolves the issue.

Thanks,

Hello,

 

I have tried it on the apk and the database works fine. The 2D model is displaying but the targetting doesn't work. Why could it not displaying on unity or even why didn't he creates a good prefab ? Moreover, it says "failed to load data set SunGlasses" on Unity.

 

Best regards.

Hello,

Can you try loading the device database into our Android test app?

https://developer.vuforia.com/downloads/tool (under the Vuforia Model Target Generator section)

https://library.vuforia.com/content/vuforia-library/en/articles/Solution/model-target-test-app-user-guide.html (User Guide)

This will eliminate any issues importing into Unity and test if your Model Targets dataset actually works.

Thanks,
