When viewing an immersive space and I open a spatial photo in Quick Look, which hides the entire app interface to show the photo. Is there a memory limit? If the inmersive space is not active, the application keep the interface.

We’re trying to build a custom player for Unity. For this, we’re using AVPlayer with AVPlayerItemVideoOutput to get textures. However, we noticed that playback is not smooth and the stream often freezes. For testing, we used this 8K video: https://deovr.com/nwfnq1 The video was played using the following code: @objc public func playVideo(urlString: String) { guard let url = URL(string: urlString) else { return } let pItem = AVPlayerItem(url: url) playerItem = pItem pItem.preferredForwardBufferDuration = 10.0 let pixelBufferAttributes: [String: Any] = [ kCVPixelBufferPixelFormatTypeKey as String: kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange, kCVPixelBufferMetalCompatibilityKey as String: true, ] let output = AVPlayerItemVideoOutput( pixelBufferAttributes: pixelBufferAttributes ) pItem.add(output) playerItemObserver = pItem.observe(\.status) { [weak self] pItem, _ in guard pItem.status == .readyToPlay else { return } self?.playerItemObserver = nil self?.player.play() } player = AVPlayer(playerItem: pItem) player.currentItem?.preferredPeakBitRate = 35_000_000 } When AVPlayerItemVideoOutput is attached, the video stutters and the log looks like this: 🟢 Playback likely to keep up 🟡 Buffer ahead: 4.08s | buffer: 4.08s 🟡 Buffer ahead: 4.08s | buffer: 4.08s 🟡 Buffer ahead: -0.07s | buffer: 0.00s 🟡 Buffer ahead: 2.94s | buffer: 3.49s 🟡 Buffer ahead: 2.50s | buffer: 4.06s 🟡 Buffer ahead: 1.74s | buffer: 4.30s 🟡 Buffer ahead: 0.74s | buffer: 4.30s 🟠 Playback may stall 🛑 Buffer empty 🟡 Buffer ahead: 0.09s | buffer: 4.30s 🟠 Playback may stall 🟠 Playback may stall 🛑 Buffer empty 🟠 Playback may stall 🟣 Buffer full 🟡 Buffer ahead: 1.41s | buffer: 1.43s 🟡 Buffer ahead: 1.41s | buffer: 1.43s 🟡 Buffer ahead: 1.07s | buffer: 1.43s 🟣 Buffer full 🟡 Buffer ahead: 0.47s | buffer: 1.65s 🟠 Playback may stall 🛑 Buffer empty 🟡 Buffer ahead: 0.10s | buffer: 1.65s 🟠 Playback may stall 🟡 Buffer ahead: 1.99s | buffer: 2.03s 🟡 Buffer ahead: 1.99s | buffer: 2.03s 🟣 Buffer full 🟣 Buffer full 🟡 Buffer ahead: 1.41s | buffer: 2.00s 🟡 Buffer ahead: 0.68s | buffer: 2.27s 🟡 Buffer ahead: 0.09s | buffer: 2.27s 🟠 Playback may stall 🛑 Buffer empty 🟠 Playback may stall When we remove AVPlayerItemVideoOutput from the player, the video plays smoothly, and the output looks like this: 🟢 Playback likely to keep up 🟡 Buffer ahead: 1.94s | buffer: 1.94s 🟡 Buffer ahead: 1.94s | buffer: 1.94s 🟡 Buffer ahead: 1.22s | buffer: 2.22s 🟡 Buffer ahead: 1.05s | buffer: 3.05s 🟡 Buffer ahead: 1.12s | buffer: 4.12s 🟡 Buffer ahead: 1.18s | buffer: 5.18s 🟡 Buffer ahead: 0.72s | buffer: 5.72s 🟡 Buffer ahead: 1.27s | buffer: 7.28s 🟡 Buffer ahead: 2.09s | buffer: 3.03s 🟡 Buffer ahead: 4.16s | buffer: 6.10s 🟡 Buffer ahead: 6.66s | buffer: 7.09s 🟡 Buffer ahead: 5.66s | buffer: 7.09s 🟡 Buffer ahead: 4.66s | buffer: 7.09s 🟡 Buffer ahead: 4.02s | buffer: 7.45s 🟡 Buffer ahead: 3.62s | buffer: 8.05s 🟡 Buffer ahead: 2.62s | buffer: 8.05s 🟡 Buffer ahead: 2.49s | buffer: 3.53s 🟡 Buffer ahead: 2.43s | buffer: 3.38s 🟡 Buffer ahead: 1.90s | buffer: 3.85s We’ve tried different attribute settings for AVPlayerItemVideoOutput. We also removed all logic related to reading frame data, but the choppy playback still remained. Can you advise whether this is a player issue or if we’re doing something wrong?

In visionOS, I'm trying to create an immersive environment which would feature several spheres in which immersive movies are visible. I'm starting from a sample code which creates a sphere, sets an immersive movie as its material, and opens it as an immersive environment. This works fine. But if I create a sphere in an open immersive environment using Reality Composer Pro and sets its material to an immersive movie, I can see the movie on the sphere while I move outside of it but if I try to get inside the sphere, it disappears. What would be the right way of doing this ?

I have a visionOS 2 project created on Xcode 16, when I updated to Xcode 26 beta5, I can't build it any more, every time it stuck in process like the picture shows below: Already tried many methods to fix this issue, such as clear build folders, but don't work.

VisionPro 开发，XCode，我想在窗口中找到一个显示模型的图片。这个模型可以改变它的材料，它不是唯一的形象，它正在改变。如何将此模型转换为图像

Are there any changes to RotationSystem: System and RotationComponent: Component that I should be aware of to see if I need to update my use in my visionOS app?

When I get close to an Entity in RealityKit wearing VisionPro. The Entity will become transparent so I can distinguish it is rendering by VisionPro instead of an object in reality world. How can I make it not transparent when I get close to the Entity?

Since using Quick Look exits you from both your app and Immersive Space. Is there a way to view immersive images within Immersive Space?

Hello When processing an ARPlaneAnchor geometry using its ARPlaneGeometry, the triangleIndices is an array of Int16. It's supposed to be an index buffer, which can only be uint16 or uint32 metal. What am I supposed to do with negative indices ? Negative indices are rare but do appear sometimes. Thank you

A few users have recently reported no longer being able to capture point clouds using our app, specifically on iPhone 15 Pro devices. We recently found an in-house device that exhibits this behavior and found that the confidenceMap contains only low confidence values, regardless of the environment being captured. Our app uses a higher confidence threshold; setting the threshold to a lower value produces noisy results as expected, so that is a non-viable option. Other LiDAR based apps have been tested with this device and the results are the same. No points, or noisy point clouds in apps that allow a lower confidence threshold setting. On devices that exhibit this behavior the "Displaying a point cloud using scene depth" Apple sample app can be used to visualize the issue. First reports of this new behavior occurred as early as iOS 18.4. Looking for recommendations on which team(s) at Apple to reach out to with these findings since the behavior manifests on only a small sample of devices.

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://developer.apple.com/documentation/realitykit/unlitmaterial/init(applypostprocesstonemap:) Is it possible to do the same for CustomMaterial? I tried initializing a CustomMaterial based on an UnlitMaterial where tone mapping is disabled, like so: let unlitMat = UnlitMaterial(applyPostProcessToneMap: false) let customMaterial = try CustomMaterial( from: unlitMat, surfaceShader: surfaceShader, geometryModifier: geometryModifier ) but that does not seem to work. The colors of my texture still look altered in comparison to a plain UnlitMaterial or a ShaderGraphMaterial where its disabled. Any hints? Thank you!

While using Screen Mirroring in developer mode within my immersive space, I noticed an alignment issue with the computer cursor (transparent circle). When I move it toward an attachment view, the cursor remains horizontal instead of aligning with the surface of the attachment view. It shows correctly on a 2D window only wrong on attachment view. Is this behavior a bug, or could it be caused by a missing or incorrect configuration on the attachment view? Want help, thanks.

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.

I have two cubes in my blender project. But one gets lost after importing the USDZ file which is exported from the blender project. It seems that Apple frameworks don't support non-English USDZ.

In an earlier beta, BillboardComponent had rotationAxis and upDirection properties which allowed more fine-grained control of how an entity rotates towards the camera. Currently, it is only possible to orient the z axis of the entity. Looking at the robot in the documentation, the rotation of its z axis causes its feet to lift off the ground. Before, it was possible to restrain the rotation to one axis (y, for example) so that the robot's feet stayed on the ground with billboard.upDirection = [0, 1, 0] billboard.rotationAxis = [0, 1, 0] Is there an alternative way to achieve this? Are these properties (or similar) coming back?

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!

I am trying to run widgets on visionOS 26. Specifically I am trying to pin them to the simulator room's walls, however I am unable to do so. Is this a limitation with the visionOS simulator right now, or am I missing a trick here?

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.

Spatial widget is a new feature of visionos 26. I notice The system’s Photo app can add a Spatial Image in the widget. I wonder if third apps can use spatial image or any 3D content in it's widget? I try to use RealityView in widget and it run with a crash. So does spatial Image in widget only supported by the system Photo app, and not available to developers now?

Apple, please provide access to face tracking blend shapes on vision os, just like you do on iOS. You have the best eye and face tracking implementation on the market, please let us use it. There is a sizable audience who will buy the headset just for it. I personally know multiple people who are not buying the headset simply because you locked those features out. No raw camera access is needed, just abstracted blendshapes values. You will make the headset so much more useful if you do this simple thing.
