    Hi guys

    I'm starting the track with an image track, then when it finds the image, I want to place an anchor here so I can link my 3D geometry to this anchor so it stays put in real world.

    My question is, after placing this anchor and linking my CG to it, how far roughly can the user move before it looses this anchor? Or it wont loose it as its now placed in real life and user can walk 70m and turn around and the CG will be where it should be, because of the anchor I placed?

    Your device won't "lose" the anchor, but as you walk away the anchor might drift on the order of centimeters depending on how well ARKit can track your position. It might help to walk slowly, but factors like time of day and the terrain itself may play a factor in device tracking quality. Worth testing I think!
