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. } }

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 ?

I exported some usd assets from IsaacSim but they are not showing up correctly on my Apple Vision Pro. Even though the mesh looks to be the correct color in Finder and I can see the Diffuse Color looks correct, the object is still just gray. It should be green!

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?

I made an animation in Blender using geometry nodes that I exported to USDC file (then I used Reality Converter to convert to USDZ) and I can see the animation when viewing from the finder but does not play after importing to RCP. Any idea how I can play the animation? Or can the animation be accessed through Xcode? Thanks!

Hi, I'm very new to 3D and am currently porting a SwiftUI iOS app to visionOS 2.0. I saw WWDC24 feature Blender in multiple spatial videos, and have begun integrating Blender models and animations into my VisionOS app (I would also like to integrate skeletons and programmatic rigging, more on that later). I'm wondering if there are “Best Practices” for this workflow - from Blender to USD to RCP 2.0 to visionOS 2 in Xcode. I’ve cobbled together the following that has some obvious holes: I’ve been able to find some pre-rigged and pre-animated models online that can serve as a great starting point. As a reference, here is a free model from SketchFab - a simple rigged skeleton with 6 built in animations: https://sketchfab.com/3d-models/skeleton-character-low-poly-8856e0138f424d68a8e0b40e185951f6 When exporting to USD from Blender, I haven’t been able to export more than one animation per USD file. Is there a workflow to export multiple animations in a single USDC file, or is this just not possible? As a temporary workaround, here is a python script I’ve been using to loop through all Blender animations, and export a model for each animation: import bpy import os # Set the directory where you want to save the USD files output_directory = “/path/to/export” # Ensure the directory exists if not os.path.exists(output_directory): os.makedirs(output_directory) # Function to export current scene as USD def export_scene_as_usd(output_path, start_frame, end_frame): bpy.context.scene.frame_start = start_frame bpy.context.scene.frame_end = end_frame # Export the scene as a USD file bpy.ops.wm.usd_export( filepath=output_path, export_animation=True ) # Save the current scene name original_scene = bpy.context.scene.name # Iterate through each action and export it as a USD file for action in bpy.data.actions: # Create a new scene for each action bpy.context.window.scene = bpy.data.scenes[original_scene].copy() new_scene = bpy.context.scene # Link the action to all relevant objects for obj in new_scene.objects: if obj.animation_data is not None: obj.animation_data.action = action # Determine the frame range for the action start_frame, end_frame = action.frame_range # Export the scene as a USD file output_path = os.path.join(output_directory, f"{action.name}.usdc") export_scene_as_usd(output_path, int(start_frame), int(end_frame)) # Delete the temporary scene to free memory bpy.data.scenes.remove(new_scene) print("Export completed.") I have also been able to successfully export rigging armatures as a single Skeleton - each “bone” showing getting imported into Reality Composer Pro 2.0 when exporting/importing manually. I would like to have all of these animations available in a single scene to be used in a RealityView in visionOS - so I have placed all animation models in a RCP scene and created named Timeline Action animations for each, showing the correct model and hiding the rest when triggering specific animations. I apply materials/textures to each so they appear the same, using Shader Graph. Then in SwiftUI I use notifications (as shown here - https://forums.developer.apple.com/forums/thread/756978) to trigger each RCP Timeline Action animation from code. Two questions: Is there a better way than to have multiple models of the same skeleton - each with a different animation - in a scene to be able to trigger multiple animations? Or would this require recreating Blender animations using skeleton rigging and keyframes from within RCP Timelines? If I want to programmatically create custom animations and move parts of the skeleton/armatures - do I need to do this by defining custom components in RCP, using IKRig and define movement of each of the “bones” in Xcode? I’m looking for any tips/tricks/workflow from experienced engineers or 3D artists that can create a more efficient/optimized workflow using Blender, USD, RCP 2 and visionOS 2 with SwiftUI. Thanks so much, I appreciate any help! I am very excited about all the new tools that keep evolving to make spatial apps really fun to build!

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

In courses like Compose interactive 3D content in Reality Composer Pro Realitykit Engineers recommended working with Reality Composer Pro to create RealityKit packages to embed in our Realitykit Xcode projects. And, comparing the workflow to Unity/Unreal, I can see the reasoning since it is nice to prepare scenes/materials/assets visually. Now when we also want to run a Xcode Cloud CI/CD pipeline this seems to come into conflict: When adding a basic *.usdz to the RealityKitContent.rkassets folder, every build we run on Xcode cloud fails with: Compile Reality Asset RealityKitContent.rkassets ❌realitytool requires Metal for this operation and it is not available in this build environment I have also found this related forum post here but it was specifically about compiling a *.skybox.

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.

Hi, I'm trying to achieve 3D photo effects using a photo and a depth map, using GeomertyModifier. The offset is getting applied correctly in Reality Composer Pro, and in Xcode, but when I launch the app, the model offset is not getting applied. here are the screenshots of shader graphs and how it looks in the app

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?

randomly, the app does not work after small changes in Reality Composer. Small changes like scaling a object a tiny bit. to fix the error, i have to change another element in reality composer and hope for the best. if this does not help, i change (transform) something else, or deactive/activate something to get the project working again. I can't see a pattern why the Reality Composer Project sometimes gets in a state where it does not compile anymore.

Hi! I have been struggling with this for a little while and most of what I've found has not helped much. I hope to find more success here. Essentially, I have a model I've made in Blender. I rigged it using Auto Rig Pro, and I've also used ARP to add a Mixamo animation to it. That all works fine in Blender. However, when I try to import this model into RCP, I don't get the animation. The "default subtree animation" is completely empty. I attribute this to my lack of experience in this field but here's what I've attempted thus far: Pushing the Mixamo keyframes into an NLA strip. I'm pretty sure this is the correct line of action, but I'm definitely not doing something right. Baking the animation (?) I've made sure that I have animation checked when I export the model! Any ideas or reference projects would be lovely. I haven't really found much that has pushed me in the right direction. This project is, unfortunately, kind of time sensitive, so I would appreciate help ASAP. Thank you and let me know if I can add anymore context!

What is recommended best practice for importing a Blender 3D file into RCP? I assume as a .usdz file? Is there a WWDC24 session or other Apple resource that best explains this. I want to make sure I provide the right format/file to RCP from Blender.

Hey everyone, I'm working on an object viewer where users can place objects in a real room using AR, and I want both visionOS (Apple Vision Pro) and iOS devices (iPad, iPhone) to participate in the same shared spatial experience. The idea is that a user with a Vision Pro can place an object, and peers using iPhones/iPads can see the same object in the same position in their AR view. I've looked into ARKit's Shared ARWorldMap and MultipeerConnectivity, but I'm not sure if this extends seamlessly to visionOS or if Apple has an official way to sync spatial data between visionOS and iOS devices. Has anyone tried sharing a spatial world between visionOS and iOS? Are there any built-in frameworks that allow for a shared multiuser AR session across these devices? If not, what would be the best way to sync object positions between them? Would love to hear if anyone has insights or experience with this! 🚀 Thanks!

We have a project which is currently being built as a XCFramework. The framework contains a custom component to be used with entities in Reality Composer Pro. I have tried to se set the RCP Package.swift file to reference the framework package for the in the dependancies. Nothing that I do with the folder path to reference the code is working. Do I need to change the project to be using Swift source code instead of a XCFramework? The component needs to be in the framework as there is a class in the framework that works directly with the custom compoent. I am able to reference the XCFramework as a Swift Package with other projects.

I want to make a model with added bones move by dragging it with gestures，This is a model exported using Blender， What I understand is using IKComponent, but I don't know how to use it specifically

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
