Hi Apple Team and Developers, First of all, I’d like to express my appreciation for the incredible results achieved using PhotogrammetrySession. I’ve been developing a portrait scanning app using Object Capture, and in many tests—especially with human models—I’ve found the reconstructed body surfaces are remarkably smooth and clean, often outperforming tools like Metashape and RealityCapture in terms of aesthetic results. However, I’ve encountered some challenges when working with complex areas like long hair overlapping the face. For instance, with female models where strands of hair partially occlude the face, the resulting mesh tends to merge the hair and facial geometry. This leads to distorted or “melted” facial features, likely due to ambiguity in the geometry estimation phase. Feature Suggestion: Would it be possible to allow developers to supply two versions of the input images: • One version (original) for texture generation • A pre-processed version (e.g., contrast-enhanced or CLAHE filtered) to guide mesh reconstruction only This would give us the flexibility to enhance edge features or shadow detail without affecting the final texture appearance. In other photogrammetry pipelines, applying image enhancement selectively before dense reconstruction improves geometry quality in low-contrast areas. Question: Is there any plan to support this kind of two-path workflow in future versions of PhotogrammetrySession? Or perhaps expose more intermediate stages or tunable parameters to developers? Also, any hints on what we can expect from WWDC 2025 regarding improvements to Object Capture or related vision/3D technologies? Thanks again for this powerful API. Looking forward to hearing insights from the team and other developers. Warm regards, KitCheng

In Reality Composer Pro, why is the Sky Sphere so much larger than the Sky Dome? By my estimate, the Sky Sphere has a radius of 100m, while the Sky only has a radius of only 12m.

Hi everyone, I’m currently using the RoomPlan API, which has been working reliably until recently. However, I’ve started encountering an intermittent error and I’m trying to understand what might be causing it. The error is triggered in the ARSession observer method: session(_ session: ARSession, didFailWithError error: Error) It has occurred on at least two devices: iPhone 14 Pro iPhone 17 Pro Here’s the full error message: ARSession failed domain=com.apple.arkit.error code=102 desc=Required sensor failed. userInfo=["NSLocalizedFailureReason": A sensor failed to deliver the required input., "NSUnderlyingError": Error Domain=AVFoundationErrorDomain Code=-11819 "Cannot Complete Action" UserInfo={NSLocalizedDescription=Cannot Complete Action, NSLocalizedRecoverySuggestion=Try again later.}, "NSLocalizedDescription": Required sensor failed.] This seems to indicate that a required sensor (likely LiDAR or camera) failed to provide input, but I’m not sure what’s causing it or why it happens only occasionally. Has anyone experienced something similar or has insight into possible causes or fixes? Thanks in advance!

Problem Description: I am developing an application that runs in the Shared Space on Apple Vision Pro using Unity. When using the UI ScrollView (Scroll View) component, I found that the Mask / RectMask2D does not function in the Shared Space. Scrolling content is not masked or cropped; it extends beyond the view boundary and is displayed directly. The same UI works correctly across platforms such as Unity Editor, iOS, and macOS, but the issue only occurs in the shared space of Vision Pro. Reproduction steps: Create a ScrollView in Unity. Add a Mask or RectMask2D to the viewport. Deploy the application to Apple Vision Pro and run it in Shared Space mode. Sliding content will not be clipped by the mask, and the masked area is entirely ineffective. Expected behavior: The content of ScrollView should be properly clipped by Mask / RectMask2D and should not render outside the mask boundary. Actual results: In the shared space of Vision Pro, the mask is ineffective, causing scrolling content to extend beyond the designated area and resulting in severe UI distortion. Environmental Information: Device: Apple Vision Pro Mode: Shared Space Unity Version: 6000.0.40f1 visionOS version: visionOS 26.0 Unity PolySpatial Version: 2.0.4 Impact This issue causes Unity UI to fail to display correctly on Vision Pro, preventing ScrollView from properly clipping content, which impacts the UI experience and interaction effects in practical applications. Expected Result: When running a Unity app in the shared space of visionOS, the Mask / RectMask2D of ScrollView functions correctly

Hello, I know that Apple bans user from accessing to raw gaze data like gaze vector (x,y,z) or eye position. But when you do research on gaze data, how did you collect them from vision pro? Is there any App to solve this problem?

Hello, I am trying to build an AVP app for real-time "zero-latency" spatial video streaming. I am trying to figure out, on a high level, the best way to do this. Currently this is my method: Server sends stereo images via a WebRTC service (ie, livekit) The WebRTC stream is converted to a CVPixelBuffer, writes them to file, plays via AVPlayer, and applies a VideoMaterial to a plane entity. However, this is a bit hacky and it seems like this won't be compatible with Apple's spatial experinces. To my understanding, Apple supports HLS streaming for spatial experiences and APMP content. However, HLS (and even Low Latency HLS) introduces a second or more of latency, likely do to the segmentation nature of HLS. Thus, HLS will not work for us. Some other alternatives I've thought of are streaming the live stream video via webrtc from the server to a local computer in the AVP's network, and then using LL-HLS to stream from the local computer to the vision pro. Still, it seems like this would introduce latency on the order of seconds. Is my current approach the best way to implement this? Or could anyone suggest a better way, perhaps something compatible with AVP's spatial experiences

I want an AR character to be able to look at a position while still playing the characters animation. So far, I managed to manually adjust a single bone rotation using skeletalComponent.poses.default = Transform( scale: baseTransform.scale, rotation: lookAtRotation, translation: baseTransform.translation ) which I run at every rendering update, while a full body animation is running. But of course, hardcoding single joints to point into a direction (in my case the head) does not look as nice, as if I were to run some inverse cinematic that includes, hips + neck + head joints. I found some good IKRig code in Composing interactive 3D content with RealityKit and Reality Composer Pro. But when I try to adjust rigs while animations are playing, the animations are usually winning over the IKRig changes to the mesh.

I am developing an IOS App that allow users to scan rooms, view the scans on device, and add notes. I need to preserve actual geometry (odd angles, chamfers, fixtures), not simplified RoomPlan boxes. Are there any easy ways to incorporate high quality texture mapping or PBR? Where is the documentation for scene reconstruction?

So with the new ManipulationComponent, we can choose "stay" and then if you drag it out of your volume, once you let go it will instantly disappear. We can "animate" it back to inside the volume, eg.: content.subscribe(to: ManipulationEvents.WillRelease.self) { event in Entity.animate( .easeInOut(duration: 1), body: { event.entity.position = [0, 0.2, 0] }, completion: {} ) }, Howeve,r for the duration that it travels outside of the volume it's invisible the whole time. In this apple video, it seems to be visible when dragging and when letting go, but perhaps that's not a volume they're dragging it out of? https://youtu.be/VtenPKrvPOU?si=y1zoZOs2IMyDzOm6&t=1748 Does anyone know how to keep the entity visible even when after letting the entity go while you animate it back towards inside of your volume?

Entity.animate() makes entity animation much easier, but in many cases, I want to break the progress because of some gestures, I couldn't find any way to do this, including tried entity.stopAllAnimations(), I have to wait till Entity.animate() completes. iOS 26 / visionOS 26

While using apple's vision pro, we noticed that we can continue to use the visionOS keyboard when we no longer actually see it in passthrough. In other words, when we focus on a field to type, visionOS displays the keyboard for us in such a way that we actually see it. Then, we noticed if we look away a little bit, either up, or down, or left, or right, in such a way that the keyboard is no longer visible by us in the passthrough, the keyboard still remains responsive to taps from our fingers at the location where it is. It seems the keyboard remains functional and responsive to taps even though we can no longer observe/see it. We are trying to figure out how to implement similar functionality in our app whereby the user can continue to manipulate a 3d entity when the user can no longer actually observe it in passthrough (like the visionOS keyboard appears to allow). I assume the visionOS keyboard has this functionality thanks to the downward facing sensors on the hardware that allow hand tracking even though the hands can no longer be observed by the user. That is likely how we can rest our hands on our lap is still be able to interact with visionOS. How can we implement a similar functionality for 3D entities? Is there a way to tap in, or to allow hand tracking, from those toward facing cameras? Is it possible to manipulate a 3D entity when it is no longer observed by the user for example when they shift their attention somewhere else in the field of vision? How does the visionOS keyboard achieve this?

I have a mesh based animation 3D model, that means every frame it’s a new mesh. I import it into RealityView, but can’t play it‘s animation, RealityKit tells me this model has no animations by using print(entity.availableAnimations).

I really love the immersive environments, but I don’t have experience with creating them. Do you have resources or tutorials you can recommend for creating these from scratch? I’ve seen the sample projects and videos, but they usually start in the middle, assuming you already have the assets created.

iOS currently restricts background Bluetooth advertising and scanning in order to preserve battery life and protect user privacy. While these restrictions serve important purposes, they also limit legitimate use cases where users have explicitly opted in to proximity-based experiences. The core challenge is that modern social applications need a way to detect when users are physically present at the same location or event without requiring every participant to keep their app in the foreground. Under the current system, background BLE advertising is heavily throttled and can only transmit a limited payload, background scanning intervals are sparse and unpredictable, peer-to-peer proximity detection cannot be maintained reliably when apps are in the background, and Background App Refresh is non-deterministic, making any kind of time-based proximity validation impossible. A proposed enhancement would be to introduce an “Enhanced Proximity Permission.” This would allow developers to enable reliable background BLE advertising and scanning for declared time windows, such as a maximum of eight hours. It would also allow devices running the same app to detect each other’s proximity using ephemeral, rotating identifiers that preserve privacy, with clear user consent and prominent indicators whenever the feature is active. Unlocking this capability would open up new categories of applications. Live events could offer automatic attendance tracking at concerts, conferences, or sports venues. Retail environments could support opt-in foot traffic analysis and dwell-time insights. Social apps could allow users to find friends at festivals, campuses, or other large venues. Safety applications could extend to crowd density monitoring and contact tracing beyond COVID-era needs. Gaming could offer real-world multiplayer experiences based on physical proximity, and transportation providers could verify rideshare pickups or measure public transit flows automatically. Privacy safeguards would remain central. Permissions would be time-boxed and expire after an event or session. A mandatory visual indicator would be displayed whenever proximity tracking is active. A user-facing dashboard would show all apps granted enhanced proximity access. Permissions would automatically be revoked after a period of non-use, and only ephemeral tokens not permanent identifiers would be broadcast. The industry impact would be significant. With this enhancement, iOS could power the next generation of location-aware social platforms while maintaining Apple’s leadership in privacy through explicit user control and transparency. Current alternatives, such as requiring users to keep apps in the foreground or deploying dedicated hardware beacons, produce poor user experiences and constrain innovation in spatial computing and social applications. Can anyone from Apple consider this change? Having to buy iBeacons is brutal and means slower adoption. Please reconsider this for users who opt in.

How can I renew visionOS Enterprise API? I've spent so much time contacting Apple Developer Support. They said they don't know the renewal process either and are "checking with the internal operations team" - but it's been 2 months with no updates. The official documentation (https://aninterestingwebsite.com/documentation/visionOS/building-spatial-experiences-for-business-apps-with-enterprise-apis#Request-the-entitlements) says: "The license file comes with an expiration date, so you need to renew it before then to ensure your entitlements continue to function." But it doesn't explain HOW to renew. When I asked Apple Support about this, they told me: "After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions." But I never received any instructions when I was first approved, and I still don't know how to renew. There's also no direct way to contact the Enterprise API team. Now my visionOS Enterprise API license has been expired for 2 months. I submitted a renewal request, but I still haven't heard anything back. Is it normal to take more than 2 months for approval? Any advice or shared experiences would be really helpful. Thanks!

When I was developing the visionOS 26beta Widget, I found that it could not work normally when the real vision OS was running, and an error would appear. Please adopt container background api It is worth mentioning that this problem does not occur on the visionOS virtual machine. Does anyone know what the reason and solution are, or whether this is a visionOS error that needs Feedback? Thank you!

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://aninterestingwebsite.com/documentation/realitykit/unlitmaterial/init(applypostprocesstonemap:) Is it possible to do the same for CustomMaterial? I tried initializing a CustomMaterial based on an UnlitMaterial where tone mapping is disabled, like so: let unlitMat = UnlitMaterial(applyPostProcessToneMap: false) let customMaterial = try CustomMaterial( from: unlitMat, surfaceShader: surfaceShader, geometryModifier: geometryModifier ) but that does not seem to work. The colors of my texture still look altered in comparison to a plain UnlitMaterial or a ShaderGraphMaterial where its disabled. Any hints? Thank you!

I am creating a vision pro app with a 3D model, it has a mesh hierarchy of head, hands, feet etc. I want the character to look towards the camera, but am not able to access head of character through sceneKit nor reality kit. when I try to print names of the child meshes, it only prints till the character, it does iterate through all the body parts. Can anyone help?

Hi, Is there a resource or sample code about how to draw an outline around a mesh in RealityKit? Typically, this is useful for visualizing a selection, like in Reality Composer Pro. How to achieve such effect? A shader material? A post-process effect in ARView or RealityRenderer? Methods such as duplicating the entity mesh, scaling it, and using material.faceCulling = .front did not look good in my experiments. Thank you.

Seeing this magical sand table, the unfolding and folding effects are similar to spreading out cards, which is very interesting. But I don't know how to achieve it. I want to see if there are any ways to achieve this effect and give some ideas. May I ask if this effect can be achieved under the existing API
