Vuforia SDK Version: 4.0 -
Description with steps to reproduce:
In the unity we place the 3d object 0,0,0 position which is directly above the marker also positioned 0,0,0 but when in play mode and even in phone after exported to apk, the 3d object is way above the marker. Also, when the marker is detected, the UI in the exported apk becomes white and there are some angles where in the screen went white but after we take the camera out of the marker the white disappears. I will post screenshots after this.
- Development OS (Mac OS X, Windows, Linux): Mac OS X - Mobile OS and Version: 7.1 - Mobile Device Manufacturer and Model name: Apple - Do the Vuforia Sample Applications show the same behavior?:

Hello? Anyone know how to fix this? Thank you.

I would like to know about this as well. My 3d model also appears to be way above the actual image marker.
In fact, I need to know more about the whole image tracking scale/position specifics.

Hello AlessandroB,

The shaking behaviour might depend on target quality (e.g. star rating) and also other factors;

Hello AlessandroB,
Thank you very much for your reply. I already checked and tried the one you sent but it is still shakey. Below is a video link in unity playmode so you can see how shakey/jerky the 3d object is.

Thank you

Thanks for the video. Play Mode is meant to be used for testing and debugging, but as it relies on a webcam, it is not representative of the tracking performance that you would get on a mobile device.
Try that on device, to see if it is better.

Thank you AlessandroB.

As I mentioned in my previous post, an important setting is the Continuous Autofocus; you can enable this with some simple code like the following:

Yes, attaching the script to the ARCamera is Ok. And yes, the fact that you see the focus changing as you move the camera is also an indication that autofocus is working as expected.
So, to summarize, you have tried:
- Continuous Autofocus
- Camera MODE QUALITY

Hello AlessandroB,
We tried the StoneAndChips dataset but it is still the same. The object is floating way above the marker and its a little bit jittery or shakey. What do you think may have cause this?
thanks,
