I've been looking for a solution for this for a while.
I have a sprite that appears on opening the app with instructions on how to use it.
Once the track is found the sprite dissappears.
What i'm looking to do is return the AR camera to its original position (facing the sprite)
So that the instructiojns appear everytime the track is lost.
If anyone has a way of doing this wether its this way or some other clever way it would be greatly appreciated.
