I attempted to use a LowLevelMesh and I referenced this sample.. I tried to change the .topology of the LowLevelMesh.Partin the initializeMeshParts function to .point. Referencing the documentation for MTLPrimitiveType.point states that "The vertex shader must provide [[point_size]], or the point size is undefined." However, in this sample, the vertex shader function is not defined. What would be the best way to implement this simply?

Not sure what is different, but I can now interact with it: struct ImmersiveView: View { @Environment(AppModel.self) private var appModel var body: some View { RealityView { content, attachments in let anchor = AnchorEntity(AnchoringComponent.Target.head) if let sceneAttachment = attachments.entity(for: "test") { sceneAttachment.position = SIMD3<Float>(0,0,-3.5) anchor.addChild(sceneAttachment) } content.add(anchor) } attachments: { Attachment(id: "test") { WebViewWrapper(webView: WKWebView()) } } } } @MainActor @Observable class AppModel { let immersiveSpaceID = "ImmersiveSpace" enum ImmersiveSpaceState { case closed case inTransition case open } var immersiveSpaceState = ImmersiveSpaceState.closed } struct WebViewWrapper: UIViewRepresentable { let webView: WKWebView func makeUIView(context: Context) -> WKWebView { let url = URL(string: "http://apple.com") webView.load(URLRequest(url: url!)) return webView } func updateUIView(_ uiView: WKWebView, context: Context) { } }
