Hi,
When viewing a spatial photo scene on the Apple Vision Pro Photos app, you can tap on the immersive icon on the top right corner to transaction from the window presenting the image as spatial3d to an immersive photo scene with spatial3DImmersive where the window borders disappear. Could someone explain how to achieve that? I tried to do it but once I transition from spatial3d to spatial3DImmersive I can see still see a rectangle around the spatial image.
Thanks.

Apple's WWDC video What’s new for the spatial web says the spatial-backdrop markup may change as it goes through the standards process (at 27:26 mark).
I have started adding spatial-backdrops to web pages, so I want to keep an eye out for status updates by Apple and follow the standards progress.
Is there any place I can keep an eye on this standards process?
Has Apple announced any feature updates or news on spatial-backdrops?
After updating to visionOS 26.2 Beta 2 (and Beta 3), I'm unable to establish a spatial connection to Vision Pro. This was working fine before the update.
To test, I've created a fresh spatialApp project from the Xcode template with zero modifications, but I'm hitting the same issue - the Vision Pro is discovered but won't connect.
Am I forgetting to update the config somewhere? Any ideas what might be causing this and how to fix it?
Thanks!

Hi everyone,
I’m trying to verify something mentioned in the WWDC session “Explore enhancements to your spatial business app.”
At timestamp 3:36, the presenter states:
“You can now access your enterprise license files directly within your Apple Developer account.”
I’ve checked every section of my Developer account, including:
• Membership and Agreements
• Certificates, Identifiers & Profiles
• App Store Connect
• Additional Resources
• Account settings
…but no UI or section exposes these enterprise license files.
Since the Vision Entitlement Services framework actively checks these licenses (for example, mainCameraAccess entitlement approval), I need to confirm the location of the new license file.
Could someone from Apple or anyone who has seen this feature clarify:
1. Where exactly do these enterprise license files appear in the Developer account UI, or
2. Whether this feature has not rolled out yet?
Any guidance or screenshots from those who have access would be invaluable.
Thanks,

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?
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!
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.
Hi. I am mixing content destined for Vision Pro. Locked to video. I have the AAX installer and the ASAF video player demonstrated in the quicktimes is nit included in the install package for pro tools. Would it be possible to post a link ?
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.

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

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?

My app is getting video from UVC device, and I wish to display it in an Immersive Space. But when I open Immersive Space, the UVC capture will just stop.AI said it's due to confliction in Camera pipeline. But I don't really understand, I don't need to use any on device camera, why it conflict with my UVC...
For the M2 Apple Vision Pro, there's "a general guideline, we recommend no more than 500 thousand triangles for an immersive scene, with 250 thousand for applications in the shared space." --https://developer.apple.com/videos/play/wwdc2024/10186/?time=147
Is there a revised recommendation for the M5 Apple Vision Pro?
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.
Hi, I'm currently implementing 180° / 360° property for immersive video in my app.
I was able to implement 360° easily by just giving VideoMaterial to flipped sphere.
However, I'm bit stuck at 180°. I want to implement by setting VideoMaterial to hemisphere mesh. But since RealityKit doesn't provide default function such like MeshResource.generateHemisphere yet, I just want to apply VideoMaterial half front visible, and half back transparent. I thought this would make my sphere looks like hemisphere.
But I can't find my way to implement this method.. I would appreciate any advice / idea / information that might help.
I am testing out the Gen 2 of the developer strap on my Vision Pro M2 and I have only been able to get USB 2 speeds when connecting it to my MacBook Pro Max M3. I used the official Apple Thunderbolt 4 cable, which does get Thunderbolt speeds on my T7 Touch drive. Has anyone figured out a solution for this issue?
The Gen 2 developer strap does advertise 20 Gb/s speeds.

Hi I know it's possible to play equirectangular VR180 video either SBS or MV-HEVC. And for fisheye video, the only way I know is to convert it into an AIVU for playback.
Is there any way to directly play fisheye video using AVPlayer? Thanks a lot!
