I believe I have created a videoMaterial and assigned it to a mesh with code I found in the Developer's Documentation but Im getting this error. "Trailing closure passed to parameter of type 'String' that does not accept a closure" I have attached a photo of the code and where the error happens. Any help will greatly be appreciated.

help me please i cant remove little messed up pixels and they are getting more and more please help me!! 2025 Macbook pro no protection screen actual screen

Anyone could share ideas or nodes setup to implement a gaussian blur on shader graph material, with a blur size parameter? Thanks!

In my Reality Composer Pro workflow for Vision Pro development, I’m using xcrun realitytool image to pre-compress textures into .ktx format, typically using ASTC block compression. These textures are used for cubemaps and environment assets. I’ve noticed that regardless of the image content—whether it’s a highly detailed photo or a completely black image—once compressed with the same ASTC block size (e.g., ASTC_8x8), the resulting .ktx file size is nearly identical. There appears to be no content-aware logic that adapts the compression ratio to the actual texture complexity. In contrast, Unreal Engine behaves differently: even when all cubemap faces are imported at the same resolution as DDS textures, the engine performs content-aware compression during packaging: Low-complexity images are compressed more aggressively The final packaged file size varies based on content complexity Since Reality Composer Pro requires textures to be pre-compressed as .ktx, there’s no opportunity for runtime optimization or per-image compression adjustment. Just wondering: is there any recommended way to implement content-aware compression for .ktx textures in Reality Composer Pro? Or any best practices to optimize .ktx sizes based on image complexity? Thanks!

I am still not finding resources to know how to replace hands in a full immersive Space.... I reached the goal by creating a ARKit session that can detect the USDZ hand mesh Joints and connect to the hand-tracked-joints.... but I feel that's not the best solution... I really want to use the RealityKit potential to track and replace hands (with USDZ skinned ones) in an immersive environment, but the only resources I found are from November 2023.... :( Can someone help me?

I am trying to loop my videoMaterial. I have researched the AXQueuePlayer and AVPlayerLooper and tried to implement them into my code. Please see attached. There are no errors showing up but the videoMaterial is no longer working. Please see the attached for the working code that plays the videoMaterial. I am stumped can anyone help me solve this? Thank you.

I have a simple visionOS app that creates an Entity, writes it to the device, and then attempts to load it. However, when the entity file get overwritten, it affects the ability for the app to load it correctly. Here is my code for saving the entity. import SwiftUI import RealityKit import UniformTypeIdentifiers struct ContentView: View { var body: some View { VStack { ToggleImmersiveSpaceButton() Button("Save Entity") { Task { // if let entity = await buildEntityHierarchy(from: urdfPath) { let type = UTType.realityFile let filename = "testing.\(type.preferredFilenameExtension ?? "bin")" let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent(filename) do { let mesh = MeshResource.generateBox(size: 1, cornerRadius: 0.05) let material = SimpleMaterial(color: .blue, isMetallic: true) let modelComponent = ModelComponent(mesh: mesh, materials: [material]) let entity = Entity() entity.components.set(modelComponent) print("Writing \(fileURL)") try await entity.write(to: fileURL) } catch { print("Failed writing") } } } } .padding() } } Every time I press "Save Entity", I see a warning similar to: Writing file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality Failed to set dependencies on asset 1941054755064863441 because NetworkAssetManager does not have an asset entity for that id. When I open the immersive space, I attempt to load the same file: import SwiftUI import RealityKit import UniformTypeIdentifiers struct ImmersiveView: View { @Environment(AppModel.self) private var appModel var body: some View { RealityView { content in guard let type = UTType.realityFile.preferredFilenameExtension else { return } let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent("testing.\(type)") guard FileManager.default.fileExists(atPath: fileURL.path) else { print("❌ File does not exist at path: \(fileURL.path)") return } if let entity = try? await Entity(contentsOf: fileURL) { content.add(entity) } } } } I also get errors after I overwrite the entity (by pressing "Save Entity" after I have successfully loaded it once). The warnings that appear when the Immersive space attempts to load the new entity are: Asset 13277375032756336327 Mesh (RealityFileAsset)URL/file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality/Mesh_0.compiledmesh failure: Asset provider load failed: type 'RealityFileAsset' -- RERealityArchive: Failed to open load stream for entry 'assets/Mesh_0.compiledmesh'.

The order of operations to make this happen: Launch app Press "Save Entity" to save the entity "Open Immersive Space" to view entity Press "Save Entity" to overwrite the entity "Open Immersive Space" to view entity, failed asset load request Also Launch app, the entity should still be save from last time the app ran "Open Immersive Space" to view entity Press "Save Entity" to overwrite the entity "Open Immersive Space" to view entity, failed asset load request NOTE: It appears I can get it to work slightly better by pressing the "Save Entity" button twice before attempting to view it again in the immersive space.

Is there any way to convert TextureResource to Image

是对原本VisionPro每个App的内存限制做了扩展嘛？放宽了内存限制么？

Reality Composer is no longer available in XCode 15 Release. Is this intended or will be available in later releases? Do I need to revert to Xcode15 Beta8 to get Reality Composer?

I made an animation in Blender using geometry nodes that I exported to USDC file (then I used Reality Converter to convert to USDZ) and I can see the animation when viewing from the finder but does not play after importing to RCP. Any idea how I can play the animation? Or can the animation be accessed through Xcode? Thanks!

Compilation of the project for the WWDC 2024 session title Compose interactive 3D content in Reality Composer Pro fails. After applying the fix mentioned here (https://developer.apple.com/forums/thread/762030?login=true), the project still won't compile. Using Xcode 16 beta 7, I get these errors: error: [xrsimulator] Component Compatibility: EnvironmentLightingConfiguration not available for 'xros 1.0', please update 'platforms' array in Package.swift error: [xrsimulator] Component Compatibility: AudioLibrary not available for 'xros 1.0', please update 'platforms' array in Package.swift error: [xrsimulator] Component Compatibility: BlendShapeWeights not available for 'xros 1.0', please update 'platforms' array in Package.swift error: [xrsimulator] Exception thrown during compile: compileFailedBecause(reason: "compatibility faults") error: Tool exited with code 1

I have no clue at all. Any suggestions are welcome. Thank you.

Hello! I am working on some cool project reconstructions for a client. They design lobby sized installations with LED walls. I am being tasked with converting these over to AR at scale. I've got my first test in headset and it looks great! However, the desire to just walk around more than the 10' x 10' safe area zone totally takes one out of the immersive VR experience - which is pretty counter intuitive. Is there any way for us developers to by pass this hard limit, so that clients who are requesting more room-scale options can actually enjoy this in VR? Alternatively, is there a way to hook up a PS5 controller to a "player start" so I can navigate inside the VR volume? I'm really trying to embrace Reality Composer Pro, but it seems extremely limiting as I wait for Unreal Engine to get its act together. sigh. Thanks for any help or suggestions.

Given my limited knowledge of physics, I would appreciate it if individuals with a solid understanding of the subject could provide insights into this matter. I have added a physical component to a entity in Reality Composer Pro, but I am seeking guidance on how to achieve the following: Make an object float in the air (with a slight downward motion reminiscent of the moon’s surface) Enable the object to move at a slow pace Implement a strong rebound force I would be grateful if you could provide appropriate values for these parameters. Thank you for your assistance.

If I create a visionOS app project, it automatically creates a RealityKitContent package. However, if I create a Multiplatform project (for visionOS, macOS, and iOS), the package is not added. Is it possible to add it manually? How? (using Xcode 16.1 beta 2)

Hello! I would like to do exactly this: https://youtu.be/Cun8K7ctKp0?si=TgWvtdw-VdlBVL0R I can't seem to find any documentation on getting a PS5 controller hooked up properly in Reality Composer Pro and Xcode, driving a character with animation (or, moving an object around freely) then over to the Vision Pro. Additionally, I would also like to learn how to use a controller to move a VR camera around a scene, so that we can navigate in custom built spaces - similar to Meta virtual environments, or Steam VR home environments. Typically, I would do this with Unreal Engine, but unfortunately, AVP support is still in its infancy there. So I figured, why not try to do it natively? Any help with concrete tutorials or documentation would be greatly appreciated. Thx!

I just do as the document in https://developer.apple.com/documentation/shadergraph/realitykit/cube-image-(realitykit) I have a .ktx file, and use CubeImage node to load it, then Convert node, but it shows black. I check it on my Vision Pro, it's still black, I don't know why? Is it something wrong? ps: I also use Image node to load .ktx file, it shows one image, so I belive .ktx file is right. I alse checked it on Vision Pro.

I am new to the graph editor and was able to achieve some results. However, I am noticing that my graphs are getting very tangled, confusing, and hard to debug. I was wondering whether: is it possible to define variables, to store the value of computations, and refer to them in other parts of the graph, without having to link them graphically? This would help in tidying the tangled mess I created. In the "Explore materials in Reality Composer Pro" video, I saw that it is possible to create "instances", but I am not sure if that is what I need. For example: does the shader compiler optimize them, so that there is no need to recompute each instance? Is there any functionality to debug the graph, trying inputs and seeing what the numeric outputs would be?
