Hello! I’m familiar with the discussion on “Sending messages to the scene”, and I’ve successfully used that code. However, I have several instances of the same model in my scene. Is it possible to make only one specific model respond to a notification? For example, can I pass something like RealityKit.NotificationTrigger.SourceEntity in userInfo or use another method to target just one instance?

help me please i cant remove little messed up pixels and they are getting more and more please help me!! 2025 Macbook pro no protection screen actual screen

I see no way to scale an entity with a hover effect. The closest I can find is by using HoverEffectComponent with a shader hover effect. Maybe I can change the scale with a ShaderGraph, but I cannot figure out how.

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.

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!

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.

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.

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?

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.

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

Is there any way to convert TextureResource to Image

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 have been experimenting some experiences in which I would like to use SharePlay to allow the app to be used by multiple users. Currently I achieved sharing a volume containing a Reality Composer Pro scene inside of it, the scene contains some entities with an animation. So far I have been able to correctly share the volume and its content, with the animation playing without problems, but once I activate SharePlay different users see different moments of the animation if no animation at all. Is there a way to synchronize animations between all the users, no matter when someone entered the SharePlay session, aside from communicating the animation time once someone joins?

I created a project using Reality Composer Pro. When I export to a .usdz file, it works well on iPhone 13, 14, 15, and 16 but not on iPhone 12 and 11. In the timeline, I use a behaviour that is on added to scene to active intro animation and loop background audio. But it does not work on old device like iPhone 12 and 11. Also, all interactive taps/touch points/audio don't seem to work too. Iphone 13,14,15,16 is on ios 18.1. iPhone 11, 12 is on ios 17.6.1. Here is sample usdz file exported from REality Composer Pro 2.0 that has problem above: https://drive.google.com/file/d/1sHZn9JABTswLq2flYjToTbWDuE5T7eNw/view?usp=sharing

I recently completed a freelance project where I was tasked with creating room-scale environments that could be used as AR elements. As a bonus, I suggested that these could be done to scale, and repurposed for eventual viewing in Vision Pro. To illustrate, I was able to quickly create a simple Immersive project in Xcode, add the USDZ file (authored in Maya, with baked lighting from Arnold) to Reality Composer Pro, and compile for quick sending to headset. I then would do screen recordings inside the immersive space, which the client loved to see. However, I am unable to walk around due to the boundary limitations. My next obvious thought is, how can I setup the “player” camera so that I can control with a PS5 controller inside AVP? In addition to Maya, I’m an Unreal Engine artist, and have been waiting patiently to get any projects compiled for AVP. With 5.5 release, I was able to get a VR Template test over to AVP, where I have rudimentary navigation control via the PS5 controller. Ideally, I’d also love to learn how to set this up natively, so I can take simple USDZ scenes created in Maya, import to RCP, setup a simple camera controller, and then be able to use this to navigate my VR Immersive spaces on Vision Pro. How can we go about doing this? Part two of this question/suggestion is, how would I go about controlling a rigged, animated character in AR/passthrough mode in a similar fashion? Thx!

Hello! Currently watching the Envision the Future: Build great apps for visionOS" webinar, and lots of questions coming up. Thx for offering this online! For those of us with "VR legs", how can we go about setting up custom hand/finger gestures that would enable us to add the functionality for teleporting and navigating within our fully Immersive environments? Both smooth, and snap turn/teleport options would be great, thx! This is adjacent to my previous question on how to setup a PS5 controller to do something similar. Think Half-Life: ALYX as the gold standard for VR navigation.

Hi, every one! I'm trying to bind timeline(animation + audio) and behaviors on an entity in reality composer pro. In xcode, I need to clone this entity and use the behavior, but I found that the behaviors are not clone(send notification but not received by reality composer pro and not execute the timeline). How can I solve this problem? Thanks!

Hi everyone, I’m working on a project in Reality Composer Pro, and I’ve encountered an issue with vertex animations. Here’s what I’ve done: I created a model in Blender, which includes two animations: One that scales the vertices of the model. Another that moves the model's position. I imported both animations into Reality Composer Pro, and the position animation works fine, but the vertex scaling animation does not seem to work. What I’m Trying to Achieve: I want the vertex scaling animation to play correctly in Reality Composer Pro alongside the movement animation. Problem: The position animation works as expected, but the vertex scaling animation does not work when applied in Reality Composer Pro. I have checked the vertex scaling animation in other software, and it works fine there. The issue seems to be specific to Reality Composer Pro. Is vertex animation scaling supported in Reality Composer Pro? If so, what might be causing this issue? Any advice or solutions would be greatly appreciated!

I need help to wrap my head around this... If I import the Reality Composer Pro package and load it into an ARView, I will see 1.3gb of memory usage and about 180-220% cpu usage. The frames will start at around 60fps, and then eventually drop to around 30fps. If I export the usdz from Reality Composer Pro and load that into the same ARView, I will see about 1gb of memory usage and around 150% cpu usage; fps holds longer at 60 but eventually drops. If I load that same usdz into a QuickLook view, I will see about 55mb of memory usage, 9-11% cpu, and the frames stay locked at 116fps. The only thing I notice is the button I have is slightly less responsive, but it all still works fine. I don't understand. How can I make the ARView work as efficiently as QuickLook?
