Opening USDZ from full URL still works fine, 3D model is displayed in AR. Note that opening USDZ file blob from Chrome on same device still works, 3D model is displayed in AR. So it appears to be a Safari regression, handling blob urls? More information in the Model-Viewer thread here: https://github.com/google/model-viewer/issues/4354 Repro links: https://modelviewer.dev/examples/scenegraph/#variants Select a material variant. Tap the AR icon. Tis will attempt to open a USDZ blob in QuickLook. 1966370 1 mail 2023-07-12 02:22:28 -0700 Also reproduces in iPadOS and visionOS (in the simulator) 1966393 2 webkit-bug-importer 2023-07-12 09:17:36 -0700 <rdar://problem/112142092> 1966441 3 ap 2023-07-12 12:59:18 -0700 *** This bug has been marked as a duplicate of bug 258957 ***
