I am new to using Vuforia in Unity3D. My goal is to import, for example a real car with an image and after turn around it with the phone. I use the "extended tracked" function. I see two problems on my androïd application.
First, I can't import real size model. My scale on Unity is (1,1,1) but when I switch on the phone the model is very little.
Secondly, The model is not fixed, it move when i move with the phone (little rotation).
Someone can have an idea of how we can solve this two problems.
