AR Foundation tracking is doing great so far but drifting has become a bit of a problem. I've got several items I want to put in 3d space but sometimes it's too many to do by hand so I've started modeling the 3d space in Unity and then using that to place objects more precisely. Is there any way to force it to 'rebuild' the 3D space around it with a very distinctive, easy to understand image like a QR code if I have several 3D models and I know exactly where I want them in 3D space. For example, let's say I have my desk mapped out in Unity, and have it 'furnished' in AR. Aligning these objects one by one can be untenable and doing it as a group is very sensitive to drifting with extended use. If I had a QR code could I hover over the QR code and force it to re-center all of the objects based on that QR code? Thanks!
