I am experiencing an issue where USDZ files exported from Blender do not display textures when opened in Apple Vision Pro Quick Look. Instead of the expected materials, the model appears completely white, as if the textures are missing or not being recognized by the rendering engine.

https://developer.apple.com/cn/augmented-reality/tools/. Why is this address missing? Reality Converter, what should we use now to convert the model

I am considering adding finger pad haptics (Data flow for haptic feedback is directed from the AVP to the fingers, not vice versa). Simple piezos wired to a wrist connection holding the driver/battery. But I'm concerned it will impact the hand tracking. Any guidance regarding gloves and/or the size of any peripherals attached to fingers? Or, if anyone has another (inexpensive) low profile option on the market please LMK. Thanks

Hi, Few days ago, Apple had another "Meet with Apple" event regarding immersive video : Create immersive media experiences for visionOS | Meet with Apple days one and 2 and it is not appearing on my Developer app in Mac. The same happened to IETF HLS Interest Day | Meet with Apple. Any tip? Kind regards , Bruno

Hi! I'm currently trying to render another XR scene in front of a RealityKit one. Actually, I'm anchoring a plane to the head with a shader to display for left/right eye side-by-side images. By default, the camera has a near plane so I can directly draw at z=0. Is there a way to change the camera near plane? Or maybe there is a better solution to overlay image/texture for left/right eyes? Ideally, I would layer some kind of CompositorLayer on RealityKit, but that's sadly not possible from what I know. Thanks in advance and have a good day!

I want to let users place 2D/3D “artworks” on detected walls and have them reappear in exactly the same real‑world spot after quitting and relaunching the app (like widgets do, but for my own entities).Environment: Xcode 26, visionOS 2.0, RealityKit + ARKitSession/WorldTrackingProvider Entities are parented to a holder that’s aligned to a wall via plane/mesh raycasts. What I’ve tried: Create a WorldAnchor at placement, save UUID + full 4×4 transform On next launch, re-create the WorldAnchor (or set the saved transform) and attach the entity Gate restore on relocalization/mesh updates and disable all raycast/search after restore Issue: After relaunch, placement still resolves relative to current device pose, not the same wall position. Questions: Is there a public API in visionOS 2.0 to persist app‑managed world anchors across sessions (room‑fixed), e.g., AnchorStore or equivalent? If not, what’s the recommended pattern to reliably restore wall‑anchored content? Are persistence features mentioned for widgets/windows available to third‑party RealityKit entities?

Hi, I am a new developer. I want to add articulated objects and deformable objects into my AR game. I haven't found any tutorial on this, I hope to interact with these objects. Please let me know if this is available in visionOS.

I am building a 360 photo viewer in VisionOS 26. Which allows the user to choose a 2 by 1 jpg and then renders it with a sphere mesh entity. And I use: TextureResource(contentsOf: url, options: options). I noticed two situations here in terms of mipmaps options. When setting "mipmapsMode: .none": The graphic quality within the "gaze area" looks sharp and clear The two poles (top and bottom) are perfectly rendered Massive shimmer around the "gaze area" When setting "mipmapsMode: .allocateAndGenerateAll": The graphic looks slightly blurrier than in ".none" within the "gaze area" The two poles are very blurry and hard to recognize the texture Much less shimmer around the "gaze area" My question would be: Is there a way to have the perfect graphic quality in ".none" without the massive shimmer? Thank you! Screenshots: mipmapsMode: .none mipmapsMode: .allocateAndGenerateAll

I want to step into portal world. I've know PortalCrossingComponent can make an entity to cross portal, but how to make device cross into portal world?

I'm currently implementing 180° / 360° immersive video for my app. I easily implemented 360° by just applying VideoMaterial to flipped sphere. But I'm stuck at 180°. I'm trying to implement by applying VideoMaterial to hemisphere (half sphere). I want to make VideoMaterial to be visible half front sphere and half back sphere transparent / clear. Would there be any advice / information / idea to implement this? Your help would be grateful.

I want to record animation with entity, then export it to .usd without using Reality Composer Pro, how to achieve that?

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.

I've encountered an unexpected crash with RoomPlan on iOS 16 devices. The odd part is the code is protected by an available check, since I'm using newer RoomPlan features. Xcode error dyld[40588]: Symbol not found: _$s8RoomPlan08CapturedA0V16USDExportOptionsV5modelAEvgZ I can repro using the Apple sample code. https://developer.apple.com/documentation/roomplan/create-a-3d-model-of-an-interior-room-by-guiding-the-user-through-an-ar-experience Modify RoomCaptureViewController.swift as follows. Remove try finalResults?.export(to: destinationURL, exportOptions: .parametric) Add if #available(iOS 17.0, *) { try finalResults?.export(to: destinationURL, exportOptions: .model) } else { try finalResults?.export(to: destinationURL, exportOptions: .parametric) } I would have expected this code to at least compile and run on older devices. When the app was targeting iOS 15, the available checks worked as expected and the app is able to launch properly.

Hey all, I'm working on a visionOS app that captures live frames from the left and right cameras of Apple Vision Pro using cameraFrame.sample(for: .left/.right). Apple provides documentation on encoding side-by-side frames into MV-HEVC spatial video using CMTaggedBuffer: Converting Side-by-Side 3D Video to MV-HEVC My question: Is there any way to render tagged frames (e.g. CMTaggedBuffer with .stereoView(.leftEye/.rightEye)) live, directly to a surface in RealityKit or Metal, without saving them to a file? I’d like to create a true stereoscopic (spatial) live video preview, not just render two images side-by-side. Any advice or insights would be greatly appreciated!

I am developing a Unity application for the Apple Vision Pro using PolySpatial and RealityKit integration. The goal is to create a graspable object (for example, a handheld cube) that includes a secondary camera. When the user grabs and moves the object, the secondary camera should render its view to a RenderTexture, which is displayed on a quad attached to the object, simulating a live camera screen. In the Unity Editor, this setup works correctly. The RenderTexture updates in real time, and the quad displays the camera’s view as expected. However, when building and running the application on the Vision Pro, the quad only displays the clear background color of the secondary camera. No scene content appears. The graspable interaction itself works fine: the object can be grabbed and moved as intended. Steps I have taken: Created a new layer (CameraFeed) and assigned the relevant objects to it. Set the secondary camera’s culling mask to render only the CameraFeed layer. Assigned the RenderTexture as the camera’s target texture. Applied the RenderTexture to an Unlit/Texture material on a quad. Confirmed the camera is active and correctly positioned relative to the object. From my research, it appears that once objects are managed by RealityKit through PolySpatial (for example, made graspable), they are no longer rendered through Unity's normal camera pipeline. Only the main XR camera (managed by RealityKit) seems able to see these objects. Secondary Unity cameras cannot render RealityKit-synced content to a RenderTexture. If this is correct, it seems there is currently no way to implement a true live secondary camera feed showing graspable objects on Vision Pro using Unity PolySpatial. My questions are: Is there any official way to enable multiple camera rendering of RealityKit-managed objects through PolySpatial? Are there known workarounds to simulate a live camera feed that still allows objects to be grabbed? Has anyone found alternative design patterns or methods for this kind of interaction? Environment: Unity 6.0 , PolySpatial 2.2.4, Apple Vision OS XR 2.2.4 Any insight or suggestions would be greatly appreciated. Thank you.

I want to create a screenshot (static image) of the current view on the Apple Vision Pro using written code in visionOS. Unfortunately, I currently can’t find a way to achieve this. The only option I’ve found so far is through Reality Composer Pro. However, since I want to accomplish this directly through code, this approach is not an option for me.

.glassEffect(.regular, in: .rect(cornerRadius: 24)) error; 'glassEffect(_:in:isEnabled:)' is unavailable in visionOS This is not surprising since visionOS already has a native glass interface that formed a model for the other OS's, but this error will create additional overhead for developers creating multi-platform apps that include visionOS.

I am working on an app that will allow a user to load and share their model files (usdz, usda, usdc). I'm looking at security options to prevent bad actors. Are there security or validation methods built into ARKit/RealityKit/CloudKit when loading models or saving them on the cloud? I want to ensure no one can inject any sort of exploit through these file types.

Hello, I am currently developing a Vision Pro VR application with Unreal Engine 5.5. Is it possible to interact with objects (grabbing, clicking on buttons)? I cannot find any information on this. Thank you.

According to the official documentation, the .blur(radius:) modifier could apply gaussian blur to a realityview. However, when applied directly to a RealityView, nothing inside it (neither 2D attachments nor 3D entities) appears to be blurred. Here’s the test code: struct ContentView: View { var body: some View { VStack(spacing: 20) { Text("Above the RealityView") .font(.title) RealityView { content, attachments in if let text = attachments.entity(for: "2dView") { text.position.y = 0.1 content.add(text) } let box = ModelEntity( mesh: .generateBox(size: 0.1), materials: [SimpleMaterial(color: .red, isMetallic: true)] ) content.add(box) } attachments: { Attachment(id: "2dView") { Text("Above the Box") .font(.title) } } .frame(width: 300, height: 300) .border(.blue) .blur(radius: 99) // Has no visual effect Text("Below the RealityView") .font(.subheadline) } .padding() } } My question: How can I make .blur(radius:) visually affect the content rendered in a RealityView? Can you provide a working example that .blur() to visually affect any part of a RealityView? Thanks!
