When I click the AR quick look icon on my website it doesn’t show the 3d model and I get the message “object could not be opened”. The USDZ is currently hosted in a google bucket. Could the problem be with the way im hosting the USDZ? If so is there a recommend place for me to host USDZ files?
I had the same problem. The Quick Look behavior seemed very weird: When clicking on the AR button, "object could not be opened" was shown, but when opening the link in a new tab the model could be opened.
Finally, I figured out why: I was referencing the USDZ file on a password protected directory (HTTP Basic Auth) of my webserver. After removing the protection, the USDZ file could be opened. Apparently, Safari does not use the current session when accessing the USDZ file.
