I'm trying to develop an immersive visionOS app, which you can move an Entity having a PerspectiveCamera as its child in immersive space, and render the camera view on 2D window. According to this thread, this seems to can be achieved using RealityRenderer. But when I added the scene entity loaded from realityKitContentBundle to realityRenderer.entities, I needed to clone all entities of the scene, otherwise all entities in the immersive space will disappear. @Observable @MainActor final class OffscreenRenderModel { private let renderer: RealityRenderer private let colorTexture: MTLTexture init(scene: Entity) throws { renderer = try RealityRenderer() // If not clone entities in the scene, all entities in the immersive space will disappear renderer.entities.append(scene.clone(recursive: true)) let camera = PerspectiveCamera() renderer.activeCamera = camera renderer.entities.append(camera) ... } } Is this the expected behavior? Or is there any other way to do this (move camera in immersive space and render its output on 2D window)? Here is my sample code: https://github.com/TAATHub/RealityKitPerspectiveCamera

Hello, I was looking back into downloading the Tracking geographic locations in AR sample app from https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar Unfortunately the Download links to the .zip of the DisplayingAPointCloudUsingSceneDepth sample project. The exact same issue occurs when trying to download the sample code from https://developer.apple.com/documentation/ARKit/creating-a-fog-effect-using-scene-depth Wondering if those links are deliberately broken because of possible deprecations. Thanks to any Apple Engineer willing to look into that.

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.

Hi, On visionOS to manage entity rotation we can rely on RotateGesture3D. We can even with the constrainedToAxis parameter authorize only rotation on an x, y or z axis or even make combinations. What I want to know is if it is possible to constrain the rotation on axis automatically. Let me explain, the functionality that I would like to implement is to constrain the rotation on an axis only once the user has started his gesture. The initial gesture the user makes should let us know which axis they want to rotate on. This would be equivalent to activating a constraint automatically on one of the axes, as if we were defining the gesture on one of the axes. RotateGesture3D(constrainedToAxis: .x) RotateGesture3D(constrainedToAxis: .y) RotateGesture3D(constrainedToAxis: .z) Is it possible to do this? If so, what would be the best way to do it? A code example would be greatly appreciated. Regards Tof

Hello, We've been working for months now on an App for the Vision Pro. (it's been great btw!) We already have an App in the App Store for iOS, and have been migrating our platform from the Microsoft Hololens 2 to the AVP: https://apps.microsoft.com/detail/9NPPP031VHD1 We require the Main Camera access and already have gotten the Enterprise.license for development purposes. Unfortunately, we cannot publish our Business App (which uses an Enterprise API) under the same Name/Bundle ID as our iOS App because it would conflict with our current Distribution Method. We arrived at the conclusion that we need a new Enterprise.license under a different Bundle ID to create a new App for the Business Store. Has anyone been in the same boat as us, and tried to publish to the Business Store while already having an App in the Public App Store under the same name? We applied to get another license for distribution under another name (with "Pro" at the end), but it's been stuck in limbo for over a month now (probably because the new bundle ID doesn't have any track record). Anyhow, thanks for any help, we're open to suggestions as to how to proceed!

I’m facing an issue while using CustomHoverEffect. In my view, there is a long title, which causes the title to be truncated. When the user hovers over it, the title should scroll. Although I have already implemented the scrolling effect, I am unsure how to trigger the scroll on hover. How should I approach this?

I found some snapshot API in developer documents, like blows: RealityKit / Views and attachments / ARView / /snapshot(saveToHDR:completion:) SceneKit / SCNView / snapshot() Is there a similar API in visionOS？and if not, how can I implement snapshot for realityview and usdz?

Hello, we have a RealityKit app that also runs on macOS via Catalyst. For specific USD assets containing particle systems we have observed a reproducible crash.

In the DestinationVideo demo, the onAppear in UpNextView is triggered again when it is closed, but I only want it to be triggered once. How can I achieve this? Alternatively, I would like to capture the button click events in the player menu, as shown in the screenshot below.

We use SceneReconstructionProvider to detect meshes in the surrounding environment and apply an OcclusionMaterial to them. // Assuming `entity` represents one of the detected mesh in the environment entity.components.set(ModelComponent( mesh: mesh, materials: [OcclusionMaterial()] )) While this correctly occludes entities placed in the immersive space, it also occludes system windows. This becomes problematic when a window is dragged into an occluded area (before or after entering the immersive space), preventing interaction with its elements. In some cases, it also makes it impossible to focus on the window’s drag handle, since this might become occluded as well after moving the window nearby. More generally, system windows can be occluded when they come into proximity with a model that has OcclusionMaterial applied. I'm aware of a change introduced in visionOS 2 regarding how occlusions interact with UI elements (as noted in the release notes). I believe this change was intended to ensure windows do not remain visible when opened in another room. However, this also introduces some challenges, as described in the scenario above. Is there a way to prevent system window occlusion while still allowing entities to be occluded by environmental features? Perhaps not using OcclusionMaterial at all? Development environment: Xcode 16.2, macOS 15.2 Run-time configuration: visionOS 2.2 and 2.3

I was watching the Developer videos, and there was mention that RealityView handles persistent world data differently and also automatically for us. I am having an issue finding the material I need to get up to speed on that. In ARKit, I was able to place a model with the world data and recall that .map data. It even stored a reference image for the scene to help match the world data. I'm looking for the information on how to implement and work with those same features with RealityView, as it seems to be better/automatically integrated? I need help being pointed in the right direction. Sample code would be amazing.

TODO Item DONE Item 问题： 点击背景三道横线的按钮时候，进行事件埋点，在onAppear方法里进行埋点操作，后续点击关闭按钮的时候，onAppear方法会重新走一遍，造成了方法重复走，无法正确统计埋点事件

When you click the button in the background of three horizontal lines, when the view is about to appear, add buried event statistics, but click the button to close it, it will repeat the view will appear method API, equivalent to the view method repeated execution twice, resulting in incorrect buried event statistics

How do I obtain the device's camera permissions when developing camera apps?

Hello All, I'm desperate to found a solution and I need your help please. I've create a simple cube in Vision OS. I can get it by hand (close my hand on it) and move it pretty where I want. But, I would like to throw it (exemple like a basket ball). Not push it, I want to have it in hand and throw it away of me with a velocity and direction = my hand move (and finger opened to release it). Please put me on the wait to do that. Cheers and thanks Mathis

my coworkers and i are guessing at what data defines an anchor. i tried searching but struggled to find anything helpful. our best guess was a combination Triangular Irregular Networks (TIN), gps, magnetic compass direction and maybe elevation sensors. is this documented anywhere? if not, can a definition or description be provided?

Hi, We are trying to port our Unity app from other XR devices to Vision Pro. Thus it's way easier for us to use the Metal rendering layer, fully immersive. And to stay true to the platform, we want to keep the gaze/pinch interaction system. But we just noticed that, unlike Polyspatial XR apps, VisionOS XR in Metal does not provide gaze info unless the user is actively pinching... Which forbids any attempt to give visual feedback on what they are looking at (buttons, etc). Is this planned in Apple's roadmap ? Thanks

How do you force quit apps on the Vision Pro simulator? I've read online you can double press the digital crown on a real Vision Pro device but there is no such button on the simulator. So far I've tried Pressing the home button twice (⇧⌘H) Pressing the Siri button twice (⌥⇧⌘H) None of them works I'm on Xcode 15.0 beta 5 (15A5209g) & visionOS 1.0 beta 2 (21N5207e)

My friend cannot build my visionOS project in the simulator. He gets the following error. Error: [xrsimulator] Exception thrown during compile: cannotGetRkassetsContents(path: "/Users/path/to/Packages/RealityKitContent/Sources/RealityKitContent/RealityKitContent.rkassets") In Xcode, he is able to open the RealityKitContent package in realityComposer Pro by clicking on the Package.realitycomposerpro file. No warnings show up wrt this error in RCP either. All scenes appear to be usable/navigable in RCP. This error only comes up when he tries to build the project in Xcode command+b. The is no other information in the Report Navigator's Build logs for this error. The error is always followed by this next error. Error: Tool exited with code 1 Yikes, please help!

Hi, When I'm looking at the RoomAnchor documentation I can see the planeAnchorIDs property. My question: How I can get an array of PlaneAnchor with planeAnchorIDs? A code example would be greatly appreciated. Regards Tof
