Hi! There were questions similar to this in the past, but the fixes no longer work for Unity 5 or Vuforia 6.2. I'm trying to change the WORLD_CENTER_MODE to DEVICE_TRACKING but it doesn't save when I try to build the app to an iOS device or when I save the project. All the code for changing world center has been internalized so I can't add anything to the Vuforia scripts like the following question suggests. https://developer.vuforia.com/forum/unity-extension-technical-discussion/fix-world-center-mode-reset-when-building-or-entering-play-mode
Any ideas? Should I revert to an older version of Vuforia?
