I could really use some help here. I tried to simplify this as much as possible so I created a bare bones app with the standard template for a volumetric view. I downloaded this usdz file from Apple.com: https://developer.apple.com/augmented-reality/quick-look/models/stratocaster/fender_stratocaster.usdz I copied that to asset to my main app bundle. I load it with this code: RealityView { content in // Add the initial RealityKit content if let scene = try? await Entity(named: "fender_stratocaster") { print("success!") content.add(scene) } But when I run it on the simulator or the device I see "success" in the console but I don't see the image.

I added error checking and also print "success" when the call is call to init the entity is successful. I see success every time. I removed the code for "scaling" and the made the usdz file from apple work. So then I changed to one that I downloaded from sketchfab - here is the link: https://sketchfab.com/search?q=Amethyst_Trunced_Dodecahedron&type=models And that one does not show. I downloaded this and added it to my main bundle. This works with Model3D. I'm not sure if this will be helpful but I print the entity object after a successful load and this is what I see: Success ▿ '' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'scene' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'Meshes' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'Sketchfab_model' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'root' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'GLTF_SceneRootNode' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'Fragment_Icosphere_2' : Entity, children: 2 ⟐ Transform ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ▿ 'Object_4' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ▿ 'Object_0' : ModelEntity ⟐ ModelComponent ⟐ Transform ⟐ SynchronizationComponent ▿ 'Object_5' : Entity, children: 1 ⟐ Transform ⟐ SynchronizationComponent ▿ 'Object_1' : ModelEntity ⟐ ModelComponent ⟐ Transform ⟐ SynchronizationComponent Updating
