Currently I want to recreate a window which is similar to system window in ImmersiveSpace. But we only can use the meter unit in RealityKit. I create a plane entity, I don't know how to set the size using meter unit to make the plane's size totally consistent with the system window.
Also, I want to know the z and y position of the system window in the immersive space.

I am experiencing an issue where USDZ files exported from Blender do not display textures when opened in Apple Vision Pro Quick Look. Instead of the expected materials, the model appears completely white, as if the textures are missing or not being recognized by the rendering engine.

We got very excited when we saw support for the PSVR2 on WWDC!
Particularly interesting is WebXR to us, so we got the controllers to give it a try.
Unfortunately they only register as gamepads in the navigator but not as XRInputDevice's
We went through the experimental flags and didn't find something that is directly related. Is there a flag we missed? If not, when do you have PSVR2 support planned for WebXR?
Hi all,
I am currently developing a game in Unity for VisionOS and I'd prefer to use the PSVR2 controllers as a source of the raycast for menu selection instead of the default VisionOS gaze for my specific use case. Is there a way to access the IMU of PSVR2 controllers to do this instead of just using eyegaze + controller click for selection? Is there a specific configuration for GCController from within Unity maybe?
Thank you!
Has anyone had success with MeshInstancesComponent? I tried to follow the sample code from What's New in RealityKit but it wouldn't compile. I was able to use one of the init overloads to get it to compile, but using it crashes both my device and the simulator. Even with one instance.
Happy new year to all!
I have created an iOS app that also runs on Apple Vision Pro.
On iOS, when you activate the fileImporter modal, you can swipe down the modal in iOS to dismiss.
However, in visionOS, this same modal CANNOT be swiped down to cancel/dismiss. If you are drilled deep into a file hierarchy, you have to navigate back to the top level to tap X to dismiss.
Is there a way to add swipe down to the visionOS implementation of fileImporter, or any other workaround so the user doesn't have to navigate back to the top to dismiss?
Again, this is not a visionOS app but an iOS app compatible for use in Vision Pro.
Thanks!
Suppose there was an immersiveSpace, and an Entity() being added to the space as child entity of the content. This entity is responsible for playing background music by calling prepareAudio, gaining a controller and play the music. (check the basic code below)
When it was playing music, a .plain window and an immersiveSpace are both presented. I believe this immersiveSpace is holding the handle of the controller so as long as immersiveSpace is open, the music won't stop.
However if I close the .plain window (by closing system-level close button), the music just stopped. But the immersiveSpace is still open. If right now I check the value of controller.isPlaying, it was still true. But you just cannot hear the music anymore.
To reproduce, simply open an visionOS template App project, selecting volume and full immersive, and replace some code inImmersiveView.swift with the code below. Also simply drag any .mp3 file and replace the AudioFileResource's name. And you could reproduce this bug.
RealityView { content in
// Add the initial RealityKit content
if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) {
content.add(immersiveContentEntity)
// Put skybox here. See example in World project available at
// https://developer.apple.com/
if let audioResource = try? await AudioFileResource(named: "anyMP3file.mp3") {
let ent = Entity()
immersiveContentEntity.addChild(ent)
let controller = ent.prepareAudio(audioResource)
controller.play()
}
}
}
I wonder why this happen? I mean how should I keep the music playing when I close the .plain window?
Thanks!
Hello, I am currently developing a Vision Pro VR application with Unreal Engine 5.5. Is it possible to interact with objects (grabbing, clicking on buttons)? I cannot find any information on this. Thank you.

Hello everyone
I would like to create my own spatial video on my Apple Vision Pro. According to all the documentation from Apple, this requires two camera angles that enhance the spatial perception. I have purchased the Enterprise license with main camera access for this purpose. However, this only gives me access to the left main camera of the glasses. Is there a way to access the right camera as well? Or is the one camera image enough to create a spatial video by splitting the image, for example?
I am open to any help and ideas. My goal is to create the video with the cameras on the glasses, not externally.
Can I combine FromToByAction and BindTarget.MaterialPath to animate my ShaderGraphMaterial. I don't know how to use the BindTarget.MaterialPath.
I'm playing about with the hand tracking systems in reality kit / Vision Pro
I thought it would be interesting if I could attach a virtual object to a hand when the hand is gripping (thought it would be fun to attach a basic cylinder to mimic a wand from Harry Potter)
I'm able to detect when the user is gripping but having trouble placing an object as though it's within the hand.
The simplest version of this is using an AnchorEntity pointing to the user's palm which kind of works, but quickly breaks the illusion when you rotate the wrist or hand.
It seems as though I will have to roll my own anchor entity using the various points of the user's hand and I thought calculating some median point between the thumb and little finger tips would be a good start but it's proven a little difficult as we need both rotation and position.
I'm already out of my depth with reality kit and matrices (and thanks to ChatGPT) I have some code, but as soon as I apply the position manually (as opposed to a hand anchor entity) it fails to render on the user's hand.
It feels like this should already have been something someone has looked in to, any ideas on what might be the issue here?
Note: HandTrackingSystem.handTracking is a HandTrackingProvider()
guard let anchors = HandTrackingSystem.handTracking.latestAnchors.leftHand else {
return
}
if
let thumb = anchors.handSkeleton?.joint(.thumbTip),
let little = anchors.handSkeleton?.joint(.littleFingerTip)
{
let thumbPos = simd_make_float3(thumb.anchorFromJointTransform.columns.3)
let littlePos = simd_make_float3(little.anchorFromJointTransform.columns.3)
let midPos = (thumbPos + littlePos) / 2
let direction = normalize(littlePos - thumbPos)
let rotation = simd_quatf(from: [0, 1, 0], to: direction)
wandEntity.transform.translation = midPos
wandEntity.transform.rotation = rotation
content.add(wandEntity)
}
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.

I like the toolbar visionOS's Safari uses for back & forward page, share, etc. It floats above the window.
My attempt to do this with ornaments isn't as satisfying as they partially cover the window. My attempts with toolbar haven't produced visible results.
Is this Safari-style toolbar for visionOS exposed by Apple in the API's? If so, could someone point me to documentation or sample code? Thanks!
I started a new project using RealityKit and RealityView, intended as an AR app on iPhone and iPad, but eventually VisionOS as well. I'm challenged because I find much of the recent documentations, WWDC videos, etc, include features that are VisionOS only.
Right now, I would simply like to create some gesture functionality that is similar to AR Quick Look defaults, meaning drag to reposition, two fingers to rotate or zoom. In the past, this would be implemented with something like:
arView.installGestures([.all], for: entity)
however, with RealityView I don't know how (or if possible) to access an ARView.
In RealityKit, I have found this doc: https://developer.apple.com/documentation/realitykit/transforming-realitykit-entities-with-gestures
However, many of the features in that posting are VisionOS only, and I've found no good documentation on the topic that is specific or at least compatible with iOS.
I know reverting to an ARView is an option, but I want to use RealityView if at all possible as I see it as more forward-looking.

In Vision OS app, We have two types of windows:
Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content.
Immersive Space Window – This opens only when a user starts streaming or playing a video.
Issue:
When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting. However, this causes the app to restart instead of resuming from its previous state.
Desired Behavior:
I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting.
Attempts & Challenges:
Tried managing opacity, visibility, and state preservation, but none worked as expected.
Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground.
Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.
Hello,
In my project, I have attached a ManipulationComponent to Entity A and as expected, I'm able interact with it using the built-in gestures. I have another Entity B which is a child of A that I would like to interact with as well, so I attempted to add a ManipulationComponent to B. However, no gestures seem to be registered on B; I can still interact with A but B cannot be interacted with despite having ManipulationComponents on both entities.
So I'm wondering if I'm just doing something wrong, if this is an issue with the ManipulationComponent, or if this is a limitation of the API.
Attached is the code used to add the ManipulationComponent to an Entity and it was done on both A and B:
let mc = ManipulationComponent()
model.components.set(mc)
var boxShape = ShapeResource.generateBox(width: 0.25, height: 0.05, depth: 0.25)
boxShape = boxShape.offsetBy(translation: simd_float3(0, -0.05, -0.25))
ManipulationComponent.configureEntity(model, collisionShapes: [boxShape])
if var mc = model.components[ManipulationComponent.self] {
mc.releaseBehavior = .stay
mc.dynamics.inertia = .low
model.components.set(mc)
}
I am using visionOS 26.0; let me know if there's any additional information needed.
I want to display a model image in the windowGroup window. This image is not unique. To display the model image, how should I convert it into an image
As in the title: openImmersiveSpace works as expected. The ImmersiveSpace in the ID opens normally but the function never resolves a Result. Here is a workaround I used to make user it was on the UI thread and scenePhase was active:
`
@MainActor func openSpaceWithStateCheck() async {
if scenePhase == .active {
Task {
switch await openImmersiveSpace(id: "RoomCaptureInteraction") {
case .opened:
isCapturingImagery = true
break
case .error:
print("!! An error occurred when trying to open the immersive space captureRoomImagery")
case .userCancelled:
print("!! The user declined opening immersive space captureRoomImagery")
@unknown default:
print("!! unknown default result of opening space")
break
}
}
} else {
print("Scene not active, deferring immersive space opening")
}
}
I'm on visionOS 2.4 and SDK 2.2.
I have tried uninstalling the app and rebuilding. Tried simply opening an empty ImmersiveSpace.
The consistency of the ImmersiveSpace opening at least means I can work around it. Even dismissImmersiveSpace works normally and closes the immersive space. But a workaround seems hamfisted.
The purpose is to create a simple web-based gallery of spatial photos and videos using static html files. I have successfully displayed spatial photos using the img tag and IMG.heic files. I can tap and hold the image to bring up the contextual menu and from there select View Spatial Photo. Is there any way to add a control to the image, like a link or overlay on the image itself, that a user can simply tap to show the image in 3D? And how to host a video file on a web page without going through a CDN/streaming service? Sample html would be much appreciated.

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!
