Hello Strasza

I just want to use simply (front and back device cameras) as texture of 3D objects while a user is detecting something. isn't possible in unity?

thank you so much 

Hello mohsenz,

The Vuforia ARCamera will take control of your webcam/device camera while Vuforia is active and therefor a webcam texture will not be available during this time. Is there something you are looking to get from the webcam texture that you cannot get from the ARCamera/Vuforia?

Thanks,

Vuforia Support
