I'm experiencing the same issue.

It appears that the texture is being saved as a cubemap. The sample imagetargets textures are 2D. I made a copy of the texture file and renamed it. When I load that texture it displays properly, but anytime you click the imagetarget, it resets to the cubemap texture.

Edit:

I just did some more testing. Tracking still works, even though you can't see the texture in Unity. Esure that the dataset is loaded and activated in the VuforiaConfiguration file

Please share your Unity + Vuforia version, the device you are testing on, and if you see any errors or relevant info present in the logs when running your app.

Thanks,

Hello there,

I'm doing a standalone Apps in android to detect my own custom marker (i have inserted the development key and imported the necessary packages inside Unity).

I have tried the set up in unity using my laptop webcam and it's working perfectly fine with the marker detected and my 3D model appearing.

Then, I imported these settings into android (my phone) and run the app. However, when I hovered my phone camera to the marker, no 3D model appeared.

I'm using Vuforia engine 8.1.7 and Unity 2018.3.12f1

Please help! Thanks in advance.

Hello everyone

I am working on vuforia  but image is not detect with laptop cam.please help me.

Hey! The same question as yours,  do you address this problem? Thanks! 

Hi @cinsicky and @Nouman083,

From your print-screen I see that you are using the Vuforia Core samples. My advice is to please make sure you print the sample apps targets ( https://library.vuforia.com/content/vuforia-library/en/articles/Solution/sample-apps-target-pdfs.html) unaltered. In addition, please make sure to avoid any glossiness on the print.

We go into detail here: https://library.vuforia.com/articles/Solution/Optimizing-Target-Detection-and-Tracking-Stability on what is recommended for an optimal detection and tracking experience.

Thank you.
