[ARKit]How to bind mash to the area with markers?Which marker technology is best used? Any ideas?

I have big model of residential area/ And i need create something like AR apple campus app.

I would like to know this also! A tutorial that shows you how to place a level in the real world would be super helpful.

I asked a similar question the other week about using something like a QR code to set the origin of the scene. That way you could align a scene just like this on a surface or real world location. I didn’t really get anywhere. It was suggested it was only possible with additional plugins.
