How to play blend shape animations or morph animations exported from blender in Vision Pro apps using Reality Kit
So I am exporting a .usdc file from blender that already has some morph animations. The animations play well in blender but when I export I cannot seem to play them in RealityKit or RCP. Entity.availableAnimations is an empty array. Not of the child objects in the entity hierarchy has an animation library component with it. Maybe I am exporting it wrong but I tried multiple combinations but doesn't seem to work. Here are my export settings in blender The original file I purchased is an FBX file that has the animation but when I try to directly get it in RealityConverter it doesn't seem to play animations.

Can we access a "Locked in Place" value when a window has been locked without being snapped to a surface?
Starting in visionOS 26, users can snap windows to surfaces. These windows are locked in place and are later restored by visionOS. We can access the snapped data with surfaceSnappingInfo docs. Users can also lock a free-floating (unsnapped) window from a context menu in the window controls. Is there a way to tell when a window has been locked without being snapped to a surface?

Please provide access to face tracking blendshapes on vision os
Apple, please provide access to face tracking blend shapes on vision os, just like you do on iOS. You have the best eye and face tracking implementation on the market, please let us use it. There is a sizable audience who will buy the headset just for it. I personally know multiple people who are not buying the headset simply because you locked those features out. No raw camera access is needed, just abstracted blendshapes values. You will make the headset so much more useful if you do this simple thing.

Alternatives to SceneView
Hey there, since SceneView has been marked as „deprecated“ for SwiftUI, I‘m wondering which alternatives should be considered for the following situation: I have a SwiftUI app (for iOS and iPadOS) where users can view (with rotate, scale, move gestures) 3D models (USDZ) in a scene. The models will be downloaded from web backend and called via local URL paths. What I tested: I‘ve tried ARView in .nonAR mode, RealityView, however I didn‘t get the expected response -> User can rotate, scale the 3D models in a virtual space. ARView in nonAR mode still shows the object like in normal AR mode without camera stream. I tried to add Gestures to the RealityView on iOS - loading USDZ 3D models worked but the gestures didn’t). Model3D is only available for visionOS (that would be amazing to have it for iOS) I also checked QuickLook Preview however it works pretty strange via Filepicker etc, which is not the way how the user should load the 3D models in my app. Maybe I missed something, I couldn’t find anything which can help me. I‘m pretty much stucked adopting the latest and greatest frameworks/APIs in my App and taking the next steps porting my app to visionOS. Long story short 😃: Does someone have an idea what is the alternative to SceneView for USDZ 3D models? I appreciate your support!! Thanks in advance!

[WWDC25] For GuessTogether, can you initiate a FaceTime call via the custom SharePlay button?
Hello, For GuessTogether source code, it seems like the code assumes that you're already in a FaceTime call before pressing the custom SharePlay button (labeled "Play Guess Together"). If not already on a FaceTime call, my Apple Vision Pro and the visionOS simulator both do nothing after throwing warnings. Is this intended behavior? If so, how do I make it so that pressing the button can also initiate FaceTime calls? Is this allowed? Thank you!

Using AVAsynchronousKeyValueLoading.load() on an AVAssetTrack gives an error
I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like: let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics) This is now giving a compiler error: Type of expression is ambiguous without a type annotation I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.: let naturalSize = try? await videoTrack.load(.naturalSize) let formatDescriptions = try? await videoTrack.load(.formatDescriptions) let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)

CustomMaterial disable unlit tone mapping
Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://developer.apple.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!

RealityKit Trace Metric Max/Range for VisionOS app
Hi Nathaniel, I spoke with you yesterday in the WWDC lab. Thanks for chatting with me! Is it possible to get a link to a doc that has some key metrics I'd find in a RealityKit trace so I know if that metric is exceeding limits and probably causing a problem? Right now, I just see numbers and have no idea if a metric is high or low :). This is specifically for a VisionOS app. Thanks, Bob

Immersive environment learning material
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.

Vision OS: HUD mode windows
If I correctly understand, a new Enterprise API has been introduced In visionOS 26 allowing to fix windows to the user frame of reference, implementing a something like an "head up display", with the window tracking the user movements. Is this API only available to enterprise applications, and if so is there a plan to make it available for every kind of app?
