是对原本VisionPro每个App的内存限制做了扩展嘛？放宽了内存限制么？

I'm having a heck of a time getting this to work. I'm trying to add an event notification at the end of a timeline animation to trigger something in code but I'm not receiving the notification from RC Pro. I've watched that Compose Interactive 3D Content video quite a few times now and have tried many different ways. RC Pro has the correct ID names on the notifications. I'm not a programmer at all. Just a lowly 3D artist. Here is my code... import SwiftUI import RealityKit import RealityKitContent extension Notification.Name { static let button1Pressed = Notification.Name("button1pressed") static let button2Pressed = Notification.Name("button2pressed") static let button3Pressed = Notification.Name("button3pressed") } struct MainButtons: View { @State private var transitionToNextSceneForButton1 = false @State private var transitionToNextSceneForButton2 = false @State private var transitionToNextSceneForButton3 = false @Environment(AppModel.self) var appModel @Environment(\.dismissWindow) var dismissWindow // Notification publishers for each button private let button1PressedReceived = NotificationCenter.default.publisher(for: .button1Pressed) private let button2PressedReceived = NotificationCenter.default.publisher(for: .button2Pressed) private let button3PressedReceived = NotificationCenter.default.publisher(for: .button3Pressed) var body: some View { ZStack { RealityView { content in // Load your RC Pro scene that contains the 3D buttons. if let immersiveContentEntity = try? await Entity(named: "MainButtons", in: realityKitContentBundle) { content.add(immersiveContentEntity) } } // Optionally attach a gesture if you want to debug a generic tap: .gesture( TapGesture().targetedToAnyEntity().onEnded { value in print("3D Object tapped") _ = value.entity.applyTapForBehaviors() // Do not post a test notification here—rely on RC Pro timeline events. } ) } .onAppear { dismissWindow(id: "main") // Remove any test notification posting code. } // Listen for distinct button notifications. .onReceive(button1PressedReceived) { (output) in print("Button 1 pressed notification received") transitionToNextSceneForButton1 = true } .onReceive(button2PressedReceived.receive(on: DispatchQueue.main)) { _ in print("Button 2 pressed notification received") transitionToNextSceneForButton2 = true } .onReceive(button3PressedReceived.receive(on: DispatchQueue.main)) { _ in print("Button 3 pressed notification received") transitionToNextSceneForButton3 = true } // Present next scenes for each button as needed. For example, for button 1: .fullScreenCover(isPresented: $transitionToNextSceneForButton1) { FacilityTour() .environment(appModel) } // You can add additional fullScreenCover modifiers for button 2 and 3 transitions. } }

Is there any way to convert TextureResource to Image

I downloaded the file through Scoot, and when I remove VisionPro, the app will call the StreamDelegate method and return ". endEncountered". How can I solve this problem? Thank you！

Hi, I'm developing a prototype VisionOS game. How to access the bones or joints information when exporting a USD file from Blender to RCP? The animation in RCP works fine and the joints' information is correctly embedded in the USDA file (with usdchecker). However, RCP does not read it in USDA, USDC or USDZ. It should be possible based on Apple WWDC24 (Compose Interactive 3D content in RCP). I want to attach and detach an entity to a particular bone in certain moments. So I need the bones' data. They are standard mixamo animations. My mesh is a single unified mesh. Using Blender 4.4

I developed an app on VisionPro and created a button that allows users to exit the app instead of being forced to exit. I use the ”exit (0)“ scheme to exit the application, but when I re-enter, the loaded window is not the initial window, so is there any relevant code that can be used? Thank you

I want to render a 3d/stereoscopic video in an Apple Vision Pro window using RealityKit/RealityView. The video is a left-right stereo. The straight forward approach would be to spawn a quad, and give it a custom Shader Graph material, which has a CameraIndexSwitch. The CameraIndexSwitch chooses between the right texture vs the left texture. https://i.sstatic.net/XawqjNcg.png The issue I have here is that I have to extract the video frames from my AVSampleBufferVideoRenderer. This should work ok, but not if I'm playing FairPlay content. So, my question is, how to render stereo FairPlay videos in a SwiftUI RealityView?

That title would have made a great WWDC Sessions. Unfortunately, it seems like nothing is new in Reality Composer Pro this year. I've noticed at all versions of the Xcode Beta this summer have shipped with Reality Composer Pro version 2.0. There have been slight bumps in the build number. I haven't found any new features or seen any documentation to indicate that anything has changed. So the question is, what is the state of Reality Composer Pro? Should we continue to use this tool or start doing everything in code? A huge number of Sample Projects use Reality Composer Pro, so it seems like Apple is still using it even if they didn't update it this year.

Most models are only available as glb or fbx, so I usually reexport them into usdz using Blender. When I import them into Reality Composer Pro, Mesh, Textures etc look great, but in the Animation Library subsection all I can see is one default subtree animation. In Blender I can see all available animations and play them individually. The default subtree animation just plays the default idle animation. In fact when I open the nonlinear animation view in Blender and select a different animation as the default animation, the exported usdz shows the newly selected animation as default subtree animation. I can see in the Apple sample apps models can have multiple animations in their Animation Library. I'm using the latest Blender 4.5 and the usdz exporter should be working properly?

I have a simple visionOS app that creates an Entity, writes it to the device, and then attempts to load it. However, when the entity file get overwritten, it affects the ability for the app to load it correctly. Here is my code for saving the entity. import SwiftUI import RealityKit import UniformTypeIdentifiers struct ContentView: View { var body: some View { VStack { ToggleImmersiveSpaceButton() Button("Save Entity") { Task { // if let entity = await buildEntityHierarchy(from: urdfPath) { let type = UTType.realityFile let filename = "testing.\(type.preferredFilenameExtension ?? "bin")" let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent(filename) do { let mesh = MeshResource.generateBox(size: 1, cornerRadius: 0.05) let material = SimpleMaterial(color: .blue, isMetallic: true) let modelComponent = ModelComponent(mesh: mesh, materials: [material]) let entity = Entity() entity.components.set(modelComponent) print("Writing \(fileURL)") try await entity.write(to: fileURL) } catch { print("Failed writing") } } } } .padding() } } Every time I press "Save Entity", I see a warning similar to: Writing file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality Failed to set dependencies on asset 1941054755064863441 because NetworkAssetManager does not have an asset entity for that id. When I open the immersive space, I attempt to load the same file: import SwiftUI import RealityKit import UniformTypeIdentifiers struct ImmersiveView: View { @Environment(AppModel.self) private var appModel var body: some View { RealityView { content in guard let type = UTType.realityFile.preferredFilenameExtension else { return } let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent("testing.\(type)") guard FileManager.default.fileExists(atPath: fileURL.path) else { print("❌ File does not exist at path: \(fileURL.path)") return } if let entity = try? await Entity(contentsOf: fileURL) { content.add(entity) } } } } I also get errors after I overwrite the entity (by pressing "Save Entity" after I have successfully loaded it once). The warnings that appear when the Immersive space attempts to load the new entity are: Asset 13277375032756336327 Mesh (RealityFileAsset)URL/file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality/Mesh_0.compiledmesh failure: Asset provider load failed: type 'RealityFileAsset' -- RERealityArchive: Failed to open load stream for entry 'assets/Mesh_0.compiledmesh'.

The order of operations to make this happen: Launch app Press "Save Entity" to save the entity "Open Immersive Space" to view entity Press "Save Entity" to overwrite the entity "Open Immersive Space" to view entity, failed asset load request Also Launch app, the entity should still be save from last time the app ran "Open Immersive Space" to view entity Press "Save Entity" to overwrite the entity "Open Immersive Space" to view entity, failed asset load request NOTE: It appears I can get it to work slightly better by pressing the "Save Entity" button twice before attempting to view it again in the immersive space.

I have a scene that has been assembled in RCP but I'm losing the correct hierarchy and transforms when running the scene in the headset or the simulator. This is in RCP: This is at runtime with the debugger: As you can see the "MAIN_WAGON" entity is gone and part of the hierarchy are now children of "TRAIN_ROOT" instead. Another issue is that not only part of the hieararchy disappears, it also reverts back to default values of the transform instead of what is set in RCP: This is in RCP: This is in the simulator/headset: I'm filing a feedback ticket too and will post the number here. Anyone had a similar issue and found a fix or workaround ?

Hi there, I'm developing a visionOS app that is using the anchor points and mesh from SceneReconstructionProvider anchor updates. I load an ImmersiveSpace using a RealityView and apply a ShaderGraphMaterial (from a Shader Graph in Reality Composer Pro) to the mesh and use calls to setParameter to dynamically update the material on very rapid frequency. The mesh is locked (no more updates) before the calls to setParameter. This process works for a few minutes but then eventually I get the following error in the console: assertion failure: Index out of range (operator[]:line 789) index = 13662, max = 1 With the following stack trace: Thread 1 Queue : com.apple.main-thread (serial) #0 0x00000002880f90d0 in __abort_with_payload () #1 0x000000028812a6dc in abort_with_payload_wrapper_internal () #2 0x000000028812a710 in abort_with_payload () #3 0x0000000288003f40 in _os_crash_msg () #4 0x00000001dc9ff624 in re::ecs2::ComponentBucketsBase::addComponent () #5 0x00000001dc9ffadc in re::ecs2::ComponentBucketsBase::moveComponent () #6 0x00000001dc8b0278 in re::ecs2::MaterialParameterBlockArrayComponentStateImpl::processPreparingComponents () #7 0x00000001dc8b05e4 in re::ecs2::MaterialParameterBlockArraySystem::update () #8 0x00000001dd008744 in re::Scheduler::executePhase () #9 0x00000001dc032ec4 in re::Engine::executePhase () #10 0x0000000248121898 in RCPSharedSimulationExecuteUpdate () #11 0x00000002264e488c in __59-[MRUISharedSimulation _doJoinWithConnectionContext:error:]_block_invoke.44 () #12 0x0000000268c5fe9c in _UIUpdateSequenceRunNext () #13 0x00000002696ea540 in schedulerStepScheduledMainSectionContinue () #14 0x000000026af8d284 in UC::DriverCore::continueProcessing () #15 0x00000001a1bd4e6c in CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION () #16 0x00000001a1bd4db0 in __CFRunLoopDoSource0 () #17 0x00000001a1bd44f0 in __CFRunLoopDoSources0 () #18 0x00000001a1bd3640 in __CFRunLoopRun () #19 0x00000001a1bce284 in _CFRunLoopRunSpecificWithOptions () #20 0x00000001eff12d2c in GSEventRunModal () #21 0x00000002697de878 in -[UIApplication _run] () #22 0x00000002697e33c0 in UIApplicationMain () #23 0x00000001b56651e4 in closure #1 (Swift.UnsafeMutablePointer<Swift.Optional<Swift.UnsafeMutablePointer<Swift.Int8>>>) -> Swift.Never in SwiftUI.KitRendererCommon(Swift.AnyObject.Type) -> Swift.Never () #24 0x00000001b5664f08 in SwiftUI.runApp<τ_0_0 where τ_0_0: SwiftUI.App>(τ_0_0) -> Swift.Never () #25 0x00000001b53ad570 in static SwiftUI.App.main() -> () () #26 0x0000000101bc7b9c in static MetalRendererApp.$main() () #27 0x0000000101bc7bdc in main () #28 0x0000000197fd0284 in start () Any advice on how to solve this or prevent the error?

I've been using the MacOS XCode Reality Composer to export interactive .reality files that can be hosted on the web and linked to, triggering QuickLook to open the interactive AR experience. That works really well. I've just downloaded XCode 15 Beta which ships with the new Reality Composer Pro and I can't see a way to export to .reality files anymore. It seems that this is only for building apps that ship as native iOS etc apps, rather than that can be viewed in QuickLook. Am I missing something, or is it no longer possible to export .reality files? Thanks.

`error: [xrsimulator] Component Compatibility: EnvironmentLightingConfiguration not available for 'xros 1.0', please update 'platforms' array in Package.swift error: [xrsimulator] Exception thrown during compile: compileFailedBecause(reason: "compatibility faults") error: Tool exited with code 1

Reality Composer is no longer available in XCode 15 Release. Is this intended or will be available in later releases? Do I need to revert to Xcode15 Beta8 to get Reality Composer?

Any way to extend the video recording time in Reality Composer Pro from 3:00 to any longer value, such as editing preferences in Terminal or other workaround? Is there any way to use the strap and a USB-C cable as a live video stream input source that would mirror to Quicktime or some other video capture tool? I am assuming there is no online documentation or user manual for the strap, but please correct me if I'm wrong. Thank you.

Hello, I'm working on a visionOS project that uses Reality Composer Pro, and we are managing our project files with Git. We've noticed that simply opening and closing the Reality Composer Pro application consistently generates changes in the following files, even when no explicit modifications have been made by the developer: {ProjectName}/Packages/RealityKitContent/Package.realitycomposerpro/PluginData/*******/ShaderGraphEditorPluginID/ShaderGraphEditorPluginID {ProjectName}/Packages/RealityKitContent/Package.realitycomposerpro/WorkspaceData/SceneMetadataList.json Could you please clarify the purpose of these files? Why do they appear as modified when no direct changes are made from our end? More importantly, is it safe to add these files to our .gitignore to prevent them from being tracked by Git? We are concerned that ignoring these files might lead to unexpected issues or inconsistencies when other team members pull the latest changes, especially if these files contain critical project metadata or state that needs to be synchronized. Any insights or recommended best practices for managing Reality Composer Pro projects with Git would be greatly appreciated. Thank you for your time and assistance.

I sketched a idea for a project in Reality Composer on my iPad, thinking when I had a chance to sit down I would work it up in Xcode. However, when I got back to my computer, I discovered I cannot open a file created in Reality Composer (or the exported Reality file) in Reality Composer Pro. Am I missing something obvious here, because this seems like a huge oversight. If anyone, can let me know how to open a file created in Reality Composer in Reality Composer Pro, I would greatly appreciate it. Partly, because there seems to be objects available in Reality Composer that are not in Reality Composer Pro. Thanks Stan

Hi, I’m currently using Reality Composer Pro on macOS, and I’m trying to work with particle emitters using only the built-in tools — no Xcode, no custom Swift code. Here’s what I’m trying to achieve: 1. Is it possible to trigger a particle emitter with a tap gesture, directly inside Reality Composer Pro? 2. Can I add a particle emitter to a timeline, so that it emits at a specific time during an animation or behavior sequence? 3. Most importantly, is there a way to precisely control emission behavior — such as when particles start or stop — using visual and intuitive controls, without scripting? My goal is to set up particle effects that are interactive and timeline-controlled, but managed entirely through Reality Composer Pro’s GUI, not through code. Any suggestions, tips, or examples would be very helpful. Thanks in advance!

In Reality Composer Pro 2.0 (448.120.2), if I use the "Create new scene in the project" button more than once, this feature doesn't seem to work. The second time I use "Create new scene in the project", Reality Composer Pro displays a new empty USDA file in the project browser with the wrong icon (a yellow document icon instead of a 3D box icon). Also, it doesn't create the new scene's USDA file on disk or display the scene in entity hierarchy browser or create a new tab. Consequently, whenever I want to add more than one new scene to my project, I have to repeatedly quit and restart Reality Composer Pro. In my use of RCP just now, I had to quit and restart RCP six times to create seven new scenes. Is this a known issue? Repro steps: In a Reality Composer Pro project, create a new folder using the "add folder" icon button in the project browser. Inside the new folder, click the "Create new scene in the project" icon button. Click the "Create new scene in the project" icon button a second time. Expected behavior: A new USDA file is created on disk. The new USDA file's root entity appears in the entity hierarchy browser and a corresponding new tab is created. Observed behavior: The USDA file for this scene is not created on disk and it does not appear in the entity hierarchy browser in a new tab. In the project browser view, a yellow document icon appears and it does not appear to correspond to an actual USDA file. Thank you for any insight you can provide about this issue.
