To resume the rotation/dragGesture is working only on défaut xyz point I tried to add a custom anchor and apply the same code but cannot be dragged My guess is that the red line is causing the issue (see screenshot)

I'm trying to implement the playback of an HLS content with FairPlay, and I want to insert it into a RealityView using a VideoMaterial of a sphere. When I use unencrypted HLS content everything works correctly, but when I use FairPlay it doesn't. To initialize FairPlay I am using the following in the view: let contentKeyDelegate = ContentKeySessionDelegate(licenseURL: licenseURL, certificateURL: certificateURL) // Create the Content Key Session using the FairPlay Streaming key system. let contentKeySession = AVContentKeySession(keySystem: .fairPlayStreaming) contentKeySession.setDelegate(contentKeyDelegate, queue: DispatchQueue.main) contentKeySession.addContentKeyRecipient(asset) Has anyone else encountered this problem? Note: I'm testing in Vision Pro directly because the simulator hasn't support for FairPlay.

Every time I dismiss ImmersiveSpace with progressive ImmersionStyle and open another one I get about 30-40% of immersion level. Can immersion be set to 100% in progressive by default?

I'm currently developing an application where the models present inside a volumetric window may exceed the clipping boundaries of the window. ( Which I currently understand to be a maximum of 2m ) Because of this, as models move through the clipping boundaries, the interior of the models becomes visible. If possible, I'd like to cap these interiors with a solid fill so as to make them more visually appealing. However, as far as I can tell, I'm quite limited in how I might be able to achieve this when using RealityKit on VisionOS. Some approaches I've seen to accomplish similar effects seem to use multiple passes of model geometries rendering into stencil buffers and using that to inform whether or not a cap should be drawn. However, afiact, if I have opted into using a RealityView and RealityKit, I don't have the level of control over my render pipeline such that I can render ModelEntities and also have multiple rendering passes over the set of contained entities to render into a stencil buffer that I then provide to a separate set of "capping planes" ( how I currently imagine I might accomplish this effect ). Alternatively ( due to the nature of the models I'm using ) I considered using a height map to construct an approximation of a surface cap, but how I might use a shader to construct a height map of rendered entities seems similarly difficult using the VisionOS RealityView pipeline. It is not obvious to me how I could use a ShaderGraphMaterial to render to an arbitrary image buffer that I might then pass to other functions to use as an input; ShaderGraphMaterial seems biased to the fact that all image inputs and outputs are either literal files or the actual rendered buffer. Would anyone out there have already created an effect like this that might have some advice? Or, potentially correct any misunderstandings I have with regards to accessing the Metal pipeline for RealityView or using ShaderGraphMaterial to construct a height map?

Hello, I would like to change the aspect (scale, texture, color) of a 3D element (Model Entity) when I hovered it with my eyes. What should I do If I want to create a request for this feature? And how would I know if it will ever be considered or when it will appear?

I'm trying to build a project with a moderately complex Reality Composer Pro project, but am unable to because my Mac mini (2023, 8GB RAM) keeps running out of memory. I'm wondering if there are any known memory leaks in realitytool, but basically the tool is taking up 20-30GB (!) memory during builds. I have a Mac Pro for content creation, which is why I didn't go for more RAM on the mini – it was supposed to just be a build machine for Apple Silicon compatibility, as my Pro is Intel. But, I'm kinda stuck here. I have a scene that builds fine, but any time I had a USD – in this case a tree asset – with lots of instances, or a lot of geometry, I run into the memory issue. I've tried greatly simplifying the model, but even a 2MB USD is resulting in the crash. I'm failing to see how adding a 2MB asset would cause the memory of realitytool to balloon so much during builds. If someone from Apple is willing to look, I can provide the scene – but it's proprietary so I can't just post it publicly here.

SwiftUI in visionOS has a modifier called preferredSurroundingsEffect that takes a SurroundingsEffect. From what I can tell, there is only a single effect available: .systemDark. ImmersiveSpace(id: "MyView") { MyView() .preferredSurroundingsEffect(.systemDark) } I'd like to create another effect to tint the color of passthrough video if possible. Does anyone know how to create custom SurroundingsEffects?

When isAutoFocusEnabled is set to true, the entity in the scene keeps shaking. No focus when isAutoFocusEnabled is set to false. How to set up to solve this problem. override func viewDidLoad() { super.viewDidLoad() arView.session.delegate = self guard let arCGImage = UIImage(named: "111", in: .main, with: .none)?.cgImage else { return } let arReferenceImage = ARReferenceImage(arCGImage, orientation: .up, physicalWidth: CGFloat(0.1)) let arImages: Set<ARReferenceImage> = [arReferenceImage] let configuration = ARImageTrackingConfiguration() configuration.trackingImages = arImages configuration.maximumNumberOfTrackedImages = 1 configuration.isAutoFocusEnabled = false arView.session.run(configuration) } func session(_ session: ARSession, didAdd anchors: [ARAnchor]) { anchors.compactMap { $0 as? ARImageAnchor }.forEach { let anchor = AnchorEntity(anchor: $0) let mesh = MeshResource.generateBox(size: 0.1, cornerRadius: 0.005) let material = SimpleMaterial(color: .gray, roughness: 0.15, isMetallic: true) let model = ModelEntity(mesh: mesh, materials: [material]) model.transform.translation.y = 0.05 anchor.children.append(model) arView.scene.addAnchor(anchor) } }

I am trying to change the color of usdz asset provide by my designer. But I am unable to do. Can some help me with some sample code

I'm trying to get a similar experience to Apple TV's immersive videos, but I cannot figure out how to present the AVPlayerViewController controls detached from the video. I am able to use the same AVPlayer in a window and projected on a VideoMaterial, but I can't figure out how to just present the controls, while displaying the video only in the 3D entity, without having a 2D projection in any view. Is this even possible?

This is easy to replicate with the ObjectPlacement sample app. Just run the app, position the View behind you and enjoy building a tower with the blocks. Eventually the App will enter the background and exit Immersive Space. This is actually a big problem because while you can ignore the change of scenePhase to .background this removes the chance you have to knowing the user pinched the circle X button to close the view. You can run the Hello World app, enter Immersive Space and then close the View. Immersive Space stays up and you can't get the View back. As such you need to close Immersive Space if the user closes the View (like ObjectPlacement does). Obviously if you do that and the user doesn't look at the View then it exits Immersive Space. Either option is a bad user experience. Being able to hide the View while in Immersive Space (such that the user can't close it) would be a good option. Unfortunately while you can hide all the content, the bar and circle X button are still visible. A second option would be to have the View not go into the background if the user doesn't look at it iff they are in Immersive Space.

Hello. I am trying to load my own Image Based Lighting file in a visionOS RealityView. I used the code you get when creating a new project from scratch and selecting the immersive space to full when creating the project. With the sample file Apple provides, it works. But when I put my image in PNG, HEIC or EXR format in the same location the example file was in, it doesn't load and the error states: Failed to find resource with name "SkyboxUpscaled2" in bundle In this image you can see the file "ImageBasedLight", which is the one that comes with the project and the file "SkyboxUpscaled2" which is my own in the .exr format. if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) do{ let resource = try await EnvironmentResource(named: "SkyboxUpscaled2") let iblComponent = ImageBasedLightComponent(source: .single(resource), intensityExponent: 0.25) immersiveContentEntity.components.set(iblComponent) immersiveContentEntity.components.set(ImageBasedLightReceiverComponent(imageBasedLight: immersiveContentEntity)) }catch{ print(error.localizedDescription) } Does anyone have an idea why the file is not found? Thanks in advance!

The transparency in reality kit is not rendered properly from specific ordinal axes. It seems like it is a depth sorting issue where it is rejecting some transparent surfaces when it should not. Some view directions relative to specific ordinal axes are fine. I have not narrowed down which specific axes is the problem. This is true across particle systems and/or meshes. It is very easy to replicate this issues using multiple transparent meshes or particle systems. In the above gif you can see the problem in multiple instances, the fire and snow particles are sorted behind the terrain, which has transparency since it is a procedural blend of grass, rock, and ice, but it is correctly sorted in front of the opaque materials such the rocks and wood. In the above gif, it is two back to back grid meshes (since dual sided rendering is not supported) that have a custom surface shader to animate the mesh in a wave and also apply transperency. You can see in the distance, where the transparency seems to be rendered/overlapped correctely, but at the overlap approaches the screen (and crosses an ordinal axes) it renders black for the transparent portion of the surface, when the green of the mesh that is behind should be rendered. This is a blocking problem for the development of this demo.

I am planning to build a VisionOS app and need to get access to the persona (avatar). I have not found any information regarding integration possibilities in the docs. Does anyone know if and how I can access the user's persona? Other applications like Zoom and Teams for VisionOS use the persona, so I think it is basically possible. Apparently (if it's not fake) there is also a chess game with integrated persona: https://www.youtube.com/watch?v=mMzK8C3t14I Any help is very welcome, thanks.

For me, any View that is an Attachment will rebuild at full frame rate even with nothing changing, indeed, even with no variables in the view. In addition to causing CPU usage that isn't needed, if there are @State variables in the View they do not always update. I am updating the var on DispatchQueue.main.async and most of the time it works. On occasions it is updated instantly. On other occasions it might take 30 seconds or more before the var changes are visible. If I set a BP where the @State variables are changed I can see that the change... but the new value is not visible in the View (on VisionPro). I have also used print("title (\title)") and I can see the correct version in the console but what you see in AVP in the View is not correct (though it will, eventually update). Important to note, 70% of the time the values are updated immediately. I've tried @StateObject with a class with ObservableObject and while that made it better, it doesn't fix the issue. The App is in FullImmersion at the time. I have no way of knowing if the is related or not. Below is the latest iteration of the variable. @StateObject var alertState = AlertState() class AlertState: ObservableObject { @Published var description: String = "" @Published var title: String = "" }
