I'd appreciate if someone could advise on my problem.
I use one on-device image target and a single 3D model. I use Unity extension and then export the scene to Android project. I also use Extended tracking.
My 3D model is looking fine when it's small, see Screenshot1.png.
But if I try to make my 3D model larger by increasing the scale, and when I move camera far from the target, the model gets partially invisible, see Screenshot2.png.
