File format for android and ios

[Arumugamsix]

Can we move the object to the top and bottom in AR mode?

Can we same file format for android and iOS?

If you mean place the object on the ceiling, I believe Quick Look mode does that on iOS (though it turns the model upside-down). We don't currently support it on Android.

Yes, you can use only a GLB and we will auto-generate a USDZ on the fly for iOS: https://modelviewer.dev/examples/augmentedreality/#webXR
