I have an entity that was created using Mixamo, and it has an animation. after the animation completes the mesh of the robot is not where the entity is positioned. I want to do something like when the animation finishes, I set the root entity's transform to the mesh's transform. There are no transformations applied to any of the children of this root of the model, which means that the transformations are applied to the skeleton due the the playing of animations. Is there a way where I can apply the final position of the root of the skeleton to the root entity to make sure to position the entity where the animation has ended just before the next animation plays?

We used real-time object tracking, and with enterprise permissions, we can improve the smoothness to 30Hz, but there are still noticeable delays. On one hand, we want to know why this delay occurs; is it due to performance considerations? Because we found that the delay in hand tracking is actually very low. On the other hand, we consider that it may be due to the complexity of 3D objects, so I considered using image tracking. However, we found that there are even more serious delays in image tracking and QR code tracking. We hope to optimize it. Currently, the frame rate for recognizing images for tracking seems to be one frame per second, and we hope to increase it because object recognition and tracking can be very smooth on other Apple platforms, such as iOS. Additionally, can we appropriately consider interfaces for depth recognition to obtain depth data? We want to know what accuracy vision can achieve in measuring the physical world, as well as the accuracy in rendering on the screen. We wonder if this is related to hardware devices like radar. Also, what accuracy can we achieve in tracking the movement distance of objects?

Hi, after upgrading to 2.4.1 (from 1.0) my vision stucks on "Retrieving configuration" screen. Apple Store didn't support my case since it has been sold in USA and the product isn't still present in italian market. I don't have dev strap, how can I manage the issue? Thank you

I have an app with a visionOS target, and I want to add an iOS target. Both are based on RealityKit. I want to use a SpatialTapGesture to get the tap coordinate local to the entity tapped. In visionOS this is easy: SpatialTapGesture(coordinateSpace: .local) .targetedToAnyEntity() .onEnded { tap in let entity = tap.entity let localPoint3D = tap.convert(tap.location3D, from: .local, to: entity) // … } However, according to the docs, the convert function seems to exist only in visionOS, not in iOS. So how can I do this conversion in iOS? PS: This was already posted on StackOverflow without success. There, I tried to find a workaround, but I failed.

Hi, I'm working with CameraFrameProvider from Enterprise API. Is it always capped at 30fps, or is there something I can switch to get more? I assume it is capped at 30, so let me cram in additional question here :). If I'd get a developer strap and attach an external camera capable of doing >30fps, will I get the full stream, or some other limitation will kick in?

Hi, Could anyone share some insights on how to get and track the 3D coordinates of real objects in the environment in playgrounds? I searched for some resources and noticed ARKit, Reality may be helpful but not sure how to do it.

After re-launching the immersive space in my app 5-10 times, the WorldTrackingProvider stops working. Only restarting the app will allow it to start working again. Only on device, not the simulator. I get these errors when it happens: The device_anchor can only be queried when the world tracking provider is running. ARPredictorRemoteService <0x107cbb5e0>: Service configured with error: Error Domain=com.apple.arkit.error Code=501 "(null)" Remote Service was invalidated: <ARPredictorRemoteService: 0x107cbb5e0>, will stop all data_providers.

Hi team I don't know from this error has popped up any suggestions please Thanks Zippy Games

I have a visionOS app using immersive space with RealityView. The app adds RealityKit entities to the app's Scene instance, and uses raycast to find CollisionCastHits. I want now to write a unit test to check if the app finds the right hits.
To do so, I have to access the Scene instance to add entities, and to check if they are hit by scene.raycast. But how can I access the scene instance? I can access it e.g. after creating the RealityView via its content parameter, or via @Environment(\.realityKitScene). But this seems not to be possible in a unit test. I tried the following test function: @MainActor @Test func test() async throws { var scene: RealityKit.Scene? await withCheckedContinuation { continuation in _ = RealityView(make: { content in print("make") let entity = Entity() content.add(entity) scene = entity.scene continuation.resume() }) } #expect(scene != nil) } But this logs ◇ Test test() started.
SWIFT TASK CONTINUATION MISUSE: test() leaked its continuation! The reason is apparently that the make closure of RealityView is only called when SwiftUI calls it within the body of a SwiftUI View. So, is it possible at all to access the app's scene i a unit test?

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.

Hi! I'm currently trying to render another XR scene in front of a RealityKit one. Actually, I'm anchoring a plane to the head with a shader to display for left/right eye side-by-side images. By default, the camera has a near plane so I can directly draw at z=0. Is there a way to change the camera near plane? Or maybe there is a better solution to overlay image/texture for left/right eyes? Ideally, I would layer some kind of CompositorLayer on RealityKit, but that's sadly not possible from what I know. Thanks in advance and have a good day!

Hi, I have a question. In visionOS, when a user looks at a button and performs a pinch gesture with their index finger and thumb, the button responds. By default, this works with both the left and right hands. However, I want to disable the pinch gesture when performed with the left hand while keeping it functional with the right hand. I understand that the system settings allow users to configure input for both hands, the left hand only, or the right hand only. However, I would like to control this behavior within the app itself. Is this possible? Best regards.

I understand that the system helps maintain user comfort by automatically adjusting the opacity of content in certain situations, like when someone moves too quickly or gets too close to a physical object. The content in front of them dims briefly to allow a clearer view of their surroundings. And I'd like to know the specific distance at which the system begins to show the physical object, or what criteria are used for this adjustment.

Hello everyone, I’m developing an app for Apple Vision Pro, and I’m trying to retrieve motion data updates aligned to magnetic north by using the following method: startDeviceMotionUpdates(using: .xMagneticNorthZVertical, to: .main) { ... } The goal is to get motion data oriented to magnetic north while an ImmersiveSpace() with an immersiveStyle set to .mixed is active. However, with this setup, I receive no updates at all. If I switch to: startDeviceMotionUpdates(using: .xArbitraryZVertical, to: .main) { ... } or startDeviceMotionUpdates(to: .main) { ... } then I do receive data, but it’s not aligned as required (I specifically need .xMagneticNorthZVertical). Has anyone experienced a similar issue, or does anyone know how to enable updates aligned to magnetic north in this configuration? Thanks in advance for any insights! SDK: VisionOS 2.0

I am running a Spatial Rendering App template demo， it shows “No People Found ” “There is no one nearby to share with”. How can I stream videos rendered by Mac to my vision pro I am using macOS 26.0, visionOS 26, Xcode 26

I'm using Unity 2022.3.56f, with Apple VisionOS App Mode set to 'Virtual Reality - Fully Immersive Space'. It seems that the render resolution of my game in the Apple Vision Pro when I build is well below the native resolution of the AVP displays. I can't see a setting in XR Plug-in Management Apple visionOS options, or in Quality settings, to increase the render resolutions. Is this possible? I tried setting: UnityEngine.XR.XRSettings.eyeTextureResolutionScale= 2.0f For example, but this doesn't seem to do anything to the render resolution in the build.

As the title states, this severely limits the flexibility of multi-window applications in creating a good user experience. Even effects like the ones shown below cannot be achieved.

If I long press on an element, the sidebar disappears and then a Done appears on the screen, but nothing else changes, so what are the Environments in Vision Pro's Simulator?

Regarding the Apple Vision Pro, is there a possibility to get a kind of rental device or leasing device from Apple? Background: I'm a fresh VisionOS dev. I have a low budget. I'm living in Japan. That means Vision Pro is roughly 150% the USD price. Regards

I noticed in the latest macOS beta 3 that there was this update: A new algorithm significantly improves PhotogrammetrySession reconstruction quality of low-texture objects not captured with the ObjectCaptureSession front end. It will be downloaded and cached once in the background when the PhotogrammetrySession is used at runtime. If network isn’t available at that time, the old low quality model will be used until the new one can be downloaded. There is no code change needed to get this improved model. (145220451) I am not noticing any difference to before with the reconstructions I tested so I am assuming it's reverting to the old model but in the logs there is no way to see if it succeeds or fails to download that new model. do you have any more information on what was improved here with some examples and what we should be looking for? also how can confirm the download of that new model has not failed?
