I have a AVPlayer() which loads the video and places it on the screen ModelEntity in the immersive view using the VideoMaterial. This also makes the video untappable as it is a VideoMaterial. Here's the code for the same: let screenModelEntity = model.garageScreenEntity as! ModelEntity let modelEntityMesh = screenModelEntity.model!.mesh let url = Bundle.main.url(forResource: "<URL>", withExtension: "mp4")! let asset = AVURLAsset(url: url) let playerItem = AVPlayerItem(asset: asset) let player = AVPlayer() let material = VideoMaterial(avPlayer: player) screenModelEntity.components[ModelComponent.self] = .init(mesh: modelEntityMesh, materials: [material]) player.replaceCurrentItem(with: playerItem) return player I was able to load and play the video. However, I cannot figure out how to show the player controls (AVPlayerViewController) to the user, similar to the DestinationVideo sample app. How can I add the video player controls in this case?

I'm a newbie to Reality Composer. Have constructed a couple of simple projects Have added text, and the "A a" is displayed, but as soon as it is selected for editing Properties, Xcode crashes. Running Ventura 13.3.1, and Reality Composer 1.5, Xcode 14.3.1. Will appreciate guidance on how to fix. Thanks!

Hi everyone, is it possible to use a 3D USDZ file to train a model in Create ML, I see there is an image option but it would be good to use these files from Reality Composer from object capture? Or is this in the works for forthcoming Xcode updates? Many Thanks Stuart

hi I am not sure what is going on... I have been working on this model for a while on reality composer, and had no problem testing it that way...it always worked out perfectly. So I imported the file into a brand new Xcode project... I created a new ARApp, and used SwiftUI. I actually did it twice ... And tested the version apple has with the box. In Apple's version, the app appears but the whole part where it tries to detect planes didn't show up. So I am confused. I found a question that mentions the error messages I am getting but I am not sure how to get around it? https://developer.apple.com/forums/thread/691882 // // ContentView.swift // AppToTest-02-14-23 // // Created by M on 2/14/23. // import SwiftUI import RealityKit struct ContentView : View {   var body: some View {     return ARViewContainer().edgesIgnoringSafeArea(.all)   } } struct ARViewContainer: UIViewRepresentable {       func makeUIView(context: Context) -> ARView {           let arView = ARView(frame: .zero)           // Load the "Box" scene from the "Experience" Reality File     //let boxAnchor = try!

I've got a couple 2D PNG assets that I want to add to a scene made of a couple other udsz files in RCP (picture adding a couple 2D videogame characters to a simple 3D diorama). When I try to drag the PNGs to the workspace or the file tree…nothing happens. I found a walkthrough on Medium (called "Importing and Exporting Personalized Objects for Augmented Reality: Reality Composer and SwiftUI" for those curious as I can't link to Medium posts here) that makes it look like users could do this with simple drag-and-drop. The Medium post is from June 2023, and in the screenshots RCP visually looks a lot more like Reality Composer on iPad, so I'm assuming it's changed a lot since then? Is there still a way to do this? I've tried adding the 2D elements to a scene with Blenders "import images as planes," but I'm getting weird halos around them and was hoping RCP could make the process a bit easier/cleaner.

I'm following the Meet Reality Composer Pro walkthrough and ran into something that didn't function as expected. When I got to the step where I add five "Bird_With_Audio.usda" references to the scene, I found they did not play audio. After some trial and error, I found that Preview > Resource in each of their Spatial Audio items was set to "None." If I click the dropdown menu, I see several "Bird_Calls" groups to pick from. I checked the original Bird_With_Audio.usda that I had created, and the "Bird_Calls" audio group was correctly assigned and worked. I tried dragging a sixth Bird_With_Audio into the scene and confirmed that the Spatial Audio item suddenly empties, rendering the bird silent. I was able to go through each of the five birds and set their Spatial Audio Resource to Bird_Calls, and the group worked like the video demonstrates. While this fixed the issue, as a beginner I'd like to know why this happened. It doesn't seem right that I would build and item and then have to re-attach any sounds to it when I place it in the main scene. So…where did I mess up?

I'm using DrawableQueue to create textures that I apply to my ShaderGraphMaterial texture. My metal render is using a range of alpha values as a test. My objects displayed with the DrawableQueue texture are working as expected, but the alpha component is not working. Is this an issue with my DrawableQueue descriptor? My ShaderGraphMaterial? A missing setting on my scene objects? or some limitation in visionOS? DrawableQueue descriptor let descriptor = await TextureResource.DrawableQueue.Descriptor( pixelFormat: .rgba8Unorm, width: textureResource!.width, height: textureResource!.height, usage: [.renderTarget, .shaderRead, .shaderWrite], // Usage should match the requirements for how the texture will be used //usage: [.renderTarget], // Usage should match the requirements for how the texture will be used mipmapsMode: .none // Assuming no mipmaps are needed for the text texture ) let queue = try await TextureResource.DrawableQueue(descriptor) queue.allowsNextDrawableTimeout = true await textureResource!.replace(withDrawables: queue) Draw frame: guard let drawable = try? drawableQueue!.nextDrawable(), let commandBuffer = commandQueue?.makeCommandBuffer()//, //let renderPipelineState = renderPipelineState else { return } let renderPassDescriptor = MTLRenderPassDescriptor() renderPassDescriptor.colorAttachments[0].texture = drawable.texture renderPassDescriptor.colorAttachments[0].loadAction = .clear renderPassDescriptor.colorAttachments[0].storeAction = .store renderPassDescriptor.colorAttachments[0].clearColor = clearColor /*renderPassDescriptor.colorAttachments[0].clearColor = MTLClearColor( red: clearColor.red, green: clearColor.green, blue: clearColor.blue, alpha: 0.5 )*/ renderPassDescriptor.renderTargetHeight = drawable.texture.height renderPassDescriptor.renderTargetWidth = drawable.texture.width guard let renderEncoder = commandBuffer.makeRenderCommandEncoder(descriptor: renderPassDescriptor) else { return } renderEncoder.pushDebugGroup("DrawNextFrameWithColor") //renderEncoder.setRenderPipelineState(renderPipelineState) // No need to create a render command encoder with shaders, as we are only clearing the drawable. // Since we are just clearing the drawable to a solid color, no need to draw primitives renderEncoder.endEncoding() commandBuffer.commit() commandBuffer.waitUntilCompleted() drawable.present() }

I have been digging into learning shader graphs by watching Unity shader graph content, cause lots of the same concepts apply. One thing I noticed was that in Unity, each node in the shader graph has a little preview. I don't think this exists in Reality Composer Pro, but is there anyway to mimic it (like can I hook up a node that allows me to debug the graph at that point?) If not, I'm happy to just file a feedback about it, but just thought I'd ask!

I am very new to shaders, never used one of the large systems like Unity. However I have started exploring visionOS programming and that led me to create some effects for materials in Reality Composer Pro. I have been overwhelmed with the possibilities, but also kind of lost. I understand that RCPs shaders are based on MaterialX, so maybe there are tutorials on the web that would cover how to create procedural effects (fire, wind, water, etc)? I’ve stumbled through…but it’s slow going. Are there any good resources that talk about how to use the various nodes to create procedural effects? For example, it took me a while to figure out that using the “time” node allows me to animate cool color changes, especially when combined with various math and remap nodes. Just looking for some basic resources I think. Would the shader graph tutorials about Unity, apply to using RCP? Are the node types similar enough?

I'm working on a project wherein RealityKit for iOS will be used to display 3D files (USDZ) in a real-world environment. The model will also need to animate differently depending on which button is pressed. When using models that are downloaded from various websites or via Apple QuickLook, the code functions well. I can hold the animation in place and click a button to play it. Unfortunately, although the model (through blender) my team provided is animating in SceneKit, it does not play at all when left in the real world, not even when a button is pressed. I checked RealityKit USDZ tool, and found usdz file is not valid, they are not figure out whats wrong. Could you please help me figure out what's wrong with my USDZ file?

Hi Developers, I got a question about Reality Composer Project. How do I compress a Reality Composer Project as mine is showing up to 125MB. The file size limit is 25 MB for the Swift Student Challenge Thanks :)

Hi Developers, How do I pass a Reality Kit file to use the Reality Kit file for the AR experience: import SwiftUI import RealityKit struct HelpAR : View { var body: some View { ARViewContainer().edgesIgnoringSafeArea(.all) } } struct ARViewContainer: UIViewRepresentable { func makeUIView(context: Context) -> ARView { let arView = ARView(frame: .zero) // Create a cube model let mesh = MeshResource.generateBox(size: 0.1, cornerRadius: 0.005) let material = SimpleMaterial(color: .gray, roughness: 0.15, isMetallic: true) let model = ModelEntity(mesh: mesh, materials: [material]) model.transform.translation.y = 0.05 // Create horizontal plane anchor for the content let anchor = AnchorEntity(.plane(.horizontal, classification: .any, minimumBounds: SIMD2<Float>(0.2, 0.2))) anchor.children.append(model) // Add the horizontal plane anchor to the scene arView.scene.anchors.append(anchor) return arView } func updateUIView(_ uiView: ARView, context: Context) {} } #Preview { HelpAR() }

Dear Apple Developer Forum Community, I hope this message finds you well. I am writing to seek assistance regarding an error I encountered while attempting to create a "Hello World" application using Xcode. Upon launching Xcode and starting a new project, I followed the standard procedure for creating a simple iOS application. However, during the process, I encountered an unexpected error that halted my progress. The error message I received was [insert error message here]. I have attempted to troubleshoot the issue by see two images, but unfortunately, I have been unsuccessful in resolving it. I am reaching out to the community in the hope that someone might have encountered a similar issue or have expertise in troubleshooting Xcode errors. Any guidance, suggestions, or solutions would be greatly appreciated. Thank you very much for your time and assistance. Sincerely, Zipzy games y Games

Is it possible to render an SF Symbol to a plane in RealityKit? As an example, render it as a 2D image without any depth, like a plane? I thought of MeshResource and generateText but you cannot interpolate SF Symbols (their literal text interpretation displays instead). Perhaps rendering it as a texture on a plane? Any thoughts?

I'm trying to import the USDZ file of a model with multiple textures attached to each part of the model. When I preview the file by double-clicking on the USDZ, it views fine. However, when I import it into Reality Composer Pro, it only shows the pink striped model. I also get the message - "Multiple root level objects exist for HU_EVO_SPY-8.usdc". There are so many components of the model that binding each texture to each component will be very difficult to do manually. How can I fix the file such that when I import to Reality Composer Pro, textures are attached to the model?

Activity monitor reports that Reality Composer Pro uses 150% CPU and always is the number one energy user on my M3 mac. Unfortunately the high cpu usage continues when the app is hidden or minimized. I can understand the high usage when a scene is visible and when interacting with the scene, but this appears to be a bug. Can anyone else confirm this or have a workaround? Can the scene processing at least be paused when app is hidden? Or better yet, find out why the cpu usage is so high when the scene is not changing. Reality Composer Pro Version 1.0 (409.60.6) on Sonoma 14.3 Thanks

I create a simple primitive shape and I want to add colors on each faces of the cube. I was thinking using Shape Graph, but I have no idea on how to specify each faces with a different color. Any lead or help would be great. This tech is new so help documentions is very low
