Apple's new Spatial Personas use Gaussian Splatting, but I have not found any APIs for visionOS to display a Gaussian Splat like a PLY file. Am I just missing the Apple documentation? If not, are there common practices developers are using for displaying Gaussian Splats in visionOS?

I’m trying to use EXR lightmaps to overlay baked lighting on top of a base texture in the RCP Shader Graph. When I multiply an EXR image set to Image(float) with an 8-bit base texture, the output becomes Image(float). I can’t connect that to the BaseColor input on the UnlitSurface node, since it only accepts Color3f. I expected to be able to use a Convert node between the Multiply node and the BaseColor input, but when I do that, the result becomes black and white instead of the expected outcome: the EXR multiplied with the base texture using a baseline value of 1, where values below 1 in the EXR would darken the base texture and values above 1 would brighten it. Is there any documentation on how to properly overlay a 32-bit EXR lightmap in the RCP Shader Graph, or is the black-and-white output from the Convert node a bug?

Hi everyone! I am working on AR app and wanted to implement object occlusion because it removes drift pretty much from the object. This working great with RealityKit sample But I am unable to replicate such behaviour it with scenekit. Because scenekit does not offer object occlusion. Can we say scenekit is getting depricated, and we should re-write app in RealityKit (which is obviously a big task)?

Hi everyone, I’m encountering a memory overflow issue in my visionOS app and I’d like to confirm if this is expected behavior or if I’m missing something in cleanup. App Context The app showcases apartments in real scale using AR. Apartments are heavy USDZ models (hundreds of thousands of triangles, high-resolution textures). Users can walk inside the apartments, and performance is good even close to hardware limits. Flow The app starts in a full immersive space (RealityView) for selecting the apartment. When an apartment is selected, a new ImmersiveSpace opens and the apartment scene loads. The scene includes multiple USDZ models, EnvironmentResources, and dynamic textures for skyboxes. When the user dismisses the experience, we attempt cleanup: Nulling out all entity references. Removing ModelComponents. Clearing cached textures and skyboxes. Forcing dictionaries/collections to empty. Despite this cleanup, memory usage remains very high. Problem After dismissing the ImmersiveSpace, memory does not return to baseline. Check the attached screenshot of the profiling made using Instruments: Initial state: ~30MB (main menu). After loading models sequentially: ~3.3GB. Skybox textures bring it near ~4GB. After dismissing the experience (at ~01:00 mark): memory only drops slightly (to ~2.66GB). When loading the second apartment, memory continues to increase until ~5GB, at which point the app crashes due to memory pressure. The issue is consistently visible under VM: IOSurface in Instruments. No leaks are detected. So it looks like RealityKit (or lower-level frameworks) keeps caching meshes and textures, and does not free them when RealityView is ended. But for my use case, these resources should be fully released once the ImmersiveSpace is dismissed, since new apartments will load entirely different models and textures. Cleanup Code Example Here’s a simplified version of the cleanup I’m doing: func clearAllRoomEntities() { for (entityName, entity) in entityFromMarker { entity.removeFromParent() if let modelEntity = entity as? ModelEntity { modelEntity.components.removeAll() modelEntity.children.forEach { $0.removeFromParent() } modelEntity.clearTexturesAndMaterials() } entityFromMarker[entityName] = nil removeSkyboxPortals(from: entityName) } entityFromMarker.removeAll() } extension ModelEntity { func clearTexturesAndMaterials() { guard var modelComponent = self.model else { return } for index in modelComponent.materials.indices { removeTextures(from: &modelComponent.materials[index]) } modelComponent.materials.removeAll() self.model = modelComponent self.model = nil } private func removeTextures(from material: inout any Material) { if var pbr = material as? PhysicallyBasedMaterial { pbr.baseColor.texture = nil pbr.emissiveColor.texture = nil pbr.metallic.texture = nil pbr.roughness.texture = nil pbr.normal.texture = nil pbr.ambientOcclusion.texture = nil pbr.clearcoat.texture = nil material = pbr } else if var simple = material as? SimpleMaterial { simple.color.texture = nil material = simple } } } Questions Is this expected RealityKit behavior (textures/meshes cached internally)? Is there a way to force RealityKit to release GPU resources tied to USDZ models when they’re no longer used? Should dismissing the ImmersiveSpace automatically free those IOSurfaces, or do I need to handle this differently? Any guidance, best practices, or confirmation would be hugely appreciated. Thanks in advance!

I'm working on an application for viewing AMF models on macOS, using RealityKit. AMF supports several different ways to color models, including per-vertex color (where the color of a triangle is interpolated from vertex to vertex) as well as per-face color (where the color of the triangle is the same across the entire face). I'm trying to figure out how to support those color models using a RealityKit mesh. Apple's documentation (https://developer.apple.com/documentation/realitykit/modifying-realitykit-rendering-using-custom-materials) talks about per-vertex colors, but I haven't found a way to create a mesh that includes per-vertex colors, other than use a texture map (which might be the correct solution). Can someone give me some pointers?

Summary After updating to visionOS 26, we’ve encountered severe transparency rendering issues in RealityKit that did not exist in visionOS 2.6 and earlier. These regressions affect applications that dynamically control scene opacity (via OpacityComponent). Our app renders ultra-realistic apartment environments in real time, where users can walk or teleport inside 3D spaces. When the user moves above a speed threshold, we apply a global transparency effect to prevent physical collisions with real-world objects. Everything worked perfectly in visionOS 2.6 — the problems appeared only after upgrading to 26. Scene Setup Overview The environment consists of multiple USDZ models (e.g., architecture, rooms, furniture). We manage LODs manually for performance (e.g., walls and floors always visible in full-res, while rooms swap between low/high-res versions based on user position and field of view). Transparency is achieved using OpacityComponent, applied dynamically when the user moves. Some meshes (e.g., portals to skyboxes, glass windows) use alpha materials We also use OcclusionMaterials to prevent things to be seen through walls when scene is transparent Observed Behavior by Scenario (I can share a video showing the results of each scenario if needed.) Scenario 1 — Severe Flickering (Root Opacity) Setup: OpacityComponent applied to the root entity NO ModelSortGroupComponent used Symptoms: Strong flickering when transparency is active Triangles within the same mesh render at inconsistent opacity levels Appears as if per-triangle alpha sorting is broken Workaround: Moving the OpacityComponent from the root to each individual USDZ entity removes the per-triangle flicker Pros: No conflicts with portals or alpha materials Scenario 2 — Partially Stable, But Alpha Conflicts Setup: OpacityComponent applied per USDZ entity ModelSortGroupComponent(planarUIAlwaysBehind) applied to portal meshes Other entities have NO ModelSortGroupComponent Symptoms: Frequent alpha blending conflicts: Transparent surfaces behind other transparent surfaces flicker or disappear Example: Wine glasses behind glass doors — sometimes neither is rendered, or only one Even opaque meshes behind glass flicker due to depth buffer confusion Alpha materials sometimes render portals or the real world behind them, ignoring other geometry entirely Analysis: Appears related to internal changes in alpha sorting or depth pre-pass behavior introduced in visionOS 26 Pros: Most stable setup so far Cons: Still unreliable when OpacityComponent is active Scenario 3 — Layer Separation Attempt (Regression) Setup: Same as Scenario 2, but: Entities with alpha materials moved to separate USDZs Explicit ModelSortGroupComponent order set (alpha surfaces rendered last) Symptoms: Transparent surfaces behind other transparent surfaces flicker or disappear Depth is completely broken when there's a large transparent surface Alpha materials sometimes render portals or the real world behind them, ignoring other geometry entirely Workaround Attempt: Re-ordering and further separating models did not solve it Pros: None — this setup makes transparency unusable Conclusion There appears to be a regression in RealityKit’s handling of transparency and sorting in visionOS 26, particularly when: OpacityComponent is applied dynamically, and Scenes rely on multiple overlapping transparent materials. These issues did not exist prior to 26, and the same project (no code changes) behaves correctly on previous versions. Request We’d appreciate any insight or confirmation from Apple engineers regarding: Whether alpha sorting or opacity blending behavior changed in visionOS 26 If there are new recommended practices for combining OpacityComponent with transparent materials If a bug report already exists for this regression Thanks in advance!

Is there any support pr plans for support for for raytraced reflections in RealityKit on the Vision Pro M5? I cannot find any documentation regarding this topic.

Hello, Question re: iOS RealityView postProcess. I've got a working postProcess kernel and I'd like to add some depth-based effects to it. Theoretically I should be able to just do: encoder.setTexture(context.sourceDepthTexture, index: 1) and then in the kernel: texture2d<float, access::read> depthIn [[texture(1)]] ... outTexture.write(depthIn.read(gid), gid); And I consistently see all black rendered to the view. The postProcess shader works, so that's not the issue. It just seems to not be receiving actual depth information. (If I set a breakpoint at the encoder setTexture step, I can see preview the color texture of the scene, but the context's depthTexture looks like all NaN / blank.) I've looked at all the WWDC samples, but they include ARView for all the depth sample code, which has a different set of configuration options than RealityView. So far I haven't seen anywhere to explicitly tell RealityView "include the depth information". So I'm not sure if I'm missing something there. It appears that there is indeed a depth texture being passed, but it looks blank. Is there a working example somewhere that we can reference?

Game Controller Input Limitations in visionOS Volumetric Windows Hello Apple Developer Community, I'm developing a game for visionOS and have encountered significant limitations with game controller input when using volumetric windows (WindowGroup with .volumetric style). I'd appreciate clarification on whether this is expected behavior and any guidance on best practices. 🧩 Issue Summary When using a DualSense controller with a volumetric window in visionOS, only a subset of controller inputs are available to the app. The remaining inputs appear to be reserved by the system for UI navigation. ✅ Working Inputs (Volumetric Window) D-Pad (all directions) L3 (left thumbstick button click) R3 (right thumbstick button click) Menu button Options button ❌ Not Working Inputs (Volumetric Window) Left thumbstick analog movement (used for UI scrolling instead) Right thumbstick analog movement (used for UI scrolling instead) Face buttons (Cross, Circle, Square, Triangle / A, B, X, Y) Shoulder buttons (L1, R1) Triggers (L2, R2) Key observation: When moving the left thumbstick in a volumetric window, the window's UI scrolls vertically instead of sending input to my app's GameController handlers. Similarly, face buttons seem to be reserved for system UI interactions. ⚙️ Implementation Details I'm using the standard GameController framework: Connect to controller via GCController.controllers() Access extendedGamepad profile Set up valueChangedHandler and pressedChangedHandler for all inputs Handlers confirmed registered via logging Working inputs (D-Pad, L3, R3) trigger immediately and consistently Non-working inputs (thumbsticks, face buttons) never trigger 🧠 Critical Finding: ImmersiveSpace Works Perfectly When testing the exact same code in an ImmersiveSpace (.mixed immersion style), all controller inputs work perfectly: ✅ Both thumbsticks provide full analog input ✅ All face buttons trigger their handlers ✅ All shoulder buttons and triggers work correctly ✅ 100% success rate with no intermittent issues This suggests the issue isn't with my code, but rather how visionOS handles controller input differently between Volumetric Windows and ImmersiveSpace. 🧪 Test Environment I created a minimal test project (Controller-Playground) to isolate the issue: A simple ControllerTester class that registers all GameController handlers A visual UI showing real-time input state No game logic, RealityKit physics, or other complexity Results In volumetric window: Only D-Pad, L3, R3, Menu, Options work In ImmersiveSpace: All inputs work perfectly This confirms the limitation exists at the visionOS platform level, not in app code. 🧰 Attempted Workarounds I tried the following without success: Setting GCSupportsControllerUserInteraction = false in Info.plist Setting UIRequiresFullScreen = true Changing window styles (.plain, .volumetric) Polling vs. handler-based input approaches Various threading models (MainActor, separate thread) Result: The only way to enable full controller support is to switch to ImmersiveSpace. ❓ Questions for Apple Is this input reservation behavior in volumetric windows intended and documented? Are game controllers expected to have limited functionality in volumetric windows while full functionality is reserved for ImmersiveSpace? Is there a way to request full controller input access in a volumetric window, or is ImmersiveSpace the only option for complete controller support? Where can I find official documentation about controller input differences between window types? Are there any APIs or configuration options to disable system controller shortcuts in volumetric windows? 🎯 Impact This limitation has a significant effect on game design and architecture: Volumetric windows offer a multitasking-friendly, less immersive experience ImmersiveSpace provides full controller support but may be more immersive than some games require Games that only need basic D-Pad and button input can work fine in volumetric windows Games requiring analog sticks or face buttons must currently use ImmersiveSpace It would be very helpful if Apple could clarify or reference existing documentation regarding controller input handling in different visionOS window types. If such documentation doesn't exist yet, it might be valuable to include this information in future developer guides or best-practice documents. 🕹 Current Workaround For now, I'm using: D-Pad for character movement (digital 8-direction) R3 (right stick click) as a substitute for the "X" button This setup allows the game to function within a volumetric window, though full controller support still requires ImmersiveSpace. 📄 Request If this is expected behavior, I may have simply missed the relevant documentation — could you please point me to any existing resources that explain this design? If there isn't one yet, it would be great if future visionOS documentation could: Clearly outline controller input behavior across window types Provide guidance on when to use Volumetric Windows vs. ImmersiveSpace for games Consider adding an API option to request full controller access when appropriate If this is not expected behavior, I'm happy to file a detailed bug report with sample code. 💻 System Information visionOS: Latest Simulator Xcode: Latest version Controller: Sony DualSense Framework: GameController (standard extendedGamepad profile) Test project: Minimal reproducible example available Thank you for any clarification or guidance you can provide. This information would be valuable for many developers working on visionOS games.

When assigning a ManipulationComponent to an Entity SceneEvents.WillRemoveEntity will be called for that Entity. Expected Behavior: the Entity is not (even if temporarily) removed from the Scene and no SceneEvents will be triggered as a result of assigning a ManipulationComponent. FB20872220

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?

Can the event of long pressing the digital display in VisionPro be monitored in RealityView

I used colorpick on the view, but after converting it to a model, colorpick doesn't work. Is there any way to use colorpick

Hi, Toggling a SwiftUI menu in iOS 26 significantly reduces the framerate of an underlying SKView or ARView. Below are test cases for SpriteKit and RealityKit. I ran these tests on iOS 26.1 Beta using an iPhone 13 (A15 chip). Results were similar on iOS 26.0.1. Both scenes consist of circles and balls bouncing on the ground. The restitution of the physics bodies is set for near-perfect elasticity, so they keep bouncing indefinitely. In both SKView and ARView, the framerate drops significantly whenever the SwiftUI menu is toggled. The menu itself is simple and uses standard SwiftUI animations and styling.

Hello, I am in the process of implementing SharePlay support in my visionOS app. Everything runs fine when I test locally, but when my app is distributed via TestFlight, calling try await activity.activate() shows the SharePlay dialog as usual, but then when I start a new FaceTime call, my ImmersiveSpace gets dismissed. This is only happening when the app is distributed via TestFlight, when I run it locally the ImmersiveSpace stays active as expected. Looking at the console on my Mac I found this log: Invalid initial client settings class: UIApplicationSceneClientSettings; expected class: MRUISharedApplicationSceneClientSettings; bundle ID: com.apple.facetime; scene ID: com.apple.facetime:SFBSystemService-DDA8C751-C0C4-487E-AD85-59EF4E6C6050 Does anyone have an idea how I can fix this? It's driving me nuts and I wasted over a day looking for a workaround but so far been unsuccessful. Thanks!

Breaking Through PolySpatial's ~8k Object Limit – Seeking Alternative Approaches for Large-Scale Digital Twins Confirmed: PolySpatial make Doubles MeshFilter Count – Hard Limit at ~8k Active Objects (15.9k Total) Project Context & Research Goals I’m developing an industrial digital twin application for Apple Vision Pro using Unity’s PolySpatial framework (RealityKit rendering in Unbounded_Volume mode). The scene contains complex factory environments with: Production line equipment Many fragmented grid objects need to be merged.) Dynamic product racks (state-switchable assets) Animated worker avatars To optimize performance, I’m systematically testing visionOS’s rendering capacity limits. Through controlled stress tests, I’ve identified a critical threshold: Key Finding When the total MeshFilter count reaches 15,970 (system baseline + 7,985 user-created objects × 2 due to PolySpatial cloning), the application crashes consistently. This suggests: PolySpatial’s mirroring mechanism effectively doubles GameObject overhead An apparent hard limit exists around ~8k active mesh objects in practice Objectives for This Discussion Verify if others have encountered similar limits with PolySpatial/RealityKit Understand whether this is a: Memory constraint (per-app allocation) Render pipeline limit (Metal draw calls) Unity-specific PolySpatial behavior Explore optimization strategies beyond brute-force object reduction Why This Matters Industrial metaverse applications require rendering thousands of interactive objects . Confirming these limits will help our team: Design safer content guidelines Prioritize GPU instancing/LOD investments Potentially contribute back to PolySpatial’s optimization I’d appreciate insights from engineers who’ve: Pushed similar large-scale scenes in visionOS Worked around PolySpatial’s cloning overhead Discovered alternative capacity limits (vertices/draw calls)

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 found that unofficial apps like ChatGPT and Shadowrocket can use widgets in VisionOS 26. How is this achieved? How can I also enable widgets for apps I develop?

When using the new RealityKit Manipulation Component on Entities, indirect input will never translate the entity - no matter what settings are applied. Direct manipulation works as expected for both translation and rotation. Is this intended behaviour? This is different from how indirect manipulation works on Model3D. How else can we get translation from this component? visionOS 26 Beta 2 Build from macOS 26 Beta 2 and Xcode 26 Beta 2 Attached is replicable sample code, I have tried this in other projects with the same results. var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "MovieFilmReel", in: reelRCPBundle) { ManipulationComponent.configureEntity(immersiveContentEntity, allowedInputTypes: .all, collisionShapes: [ShapeResource.generateBox(width: 0.2, height: 0.2, depth: 0.2)]) immersiveContentEntity.position.y = 1 immersiveContentEntity.position.z = -0.5 var mc = ManipulationComponent() mc.releaseBehavior = .stay immersiveContentEntity.components.set(mc) content.add(immersiveContentEntity) } } }

Since updating to iOS 26.0 (and confirmed on 26.1), ARBodyTrackingConfiguration no longer detects a valid ARBodyAnchor on devices with LiDAR (e.g., iPhone 15 Pro, iPhone 17 Pro Max). This issue reproduces in custom projects and Apple’s official sample “Capturing Body Motion in 3D”. The AR session runs normally, but the delegate call: func session(_ session: ARSession, didUpdate anchors: [ARAnchor]) never yields an ARBodyAnchor with valid joint transforms. All joints return nil when calling: body.skeleton.modelTransform(for: jointName) resulting in 0 valid joints per frame. Environment • Device: iPhone 17 Pro Max (LiDAR) • iOS: 26.0 / 26.1 • Xcode: 16.0 (stable) • Framework: ARKit + RealityKit • Configuration used: config.worldAlignment = .gravityAndHeading config.isAutoFocusEnabled = true config.environmentTexturing = .none session.run(config) Also tested: with and without frameSemantics = .bodyDetection Expected Behavior ARBodyAnchor should be detected and body.skeleton should contain ~89 valid joints with continuous updates.
