    I'm struggling to get reliable tracking using the ARKIT AunityARImageAnchor Example.
    The spawne prefab always seems to wobble a bit.

    Here's what I know about sizing:
    Physical size on the scene is set at 0.06m for the marker
    This seems to relate to the diagonal size of the marker.
    The horizontal size would be 0.043m

    I have tried both, but still getting wobbles.

    Does anyone know the exact right size to print out the markers?
    Am I right in assuming that the size of the printed maret has to be perfect?

    Thanks for any tips :)

    In case anyone else is having trouble - be aware that unity seems to autoscale imported images to the nearest number like 1024x1024 or 2048x2048 - just untick the appropriate box to stop your AR anchor image being rescaled by the unity IDE.
    This improved my Image recognition results.
