We are building an AR experience for deployment on iphones. We are using Unity but it looks as if Reality Composer Pro has better features for spatial audio. I am not sure if Reality Composer Pro can only be used for Vision Pro or can it also be used for deployment on Iphone or ipad.

Hello! I’ve got a USDZ export from Maya pipeline working with animation, and they load up nicely in the Vision Pro. I’ve been checking out the animated sample files in the Augmented Reality/Quick Loop sample page, specifically, the first three at the top of the page. I would like to know how they are created. I’m a 3d modeler and animator, not a programmer, so dipping my toe in RCP and Xcode/SwiftUI, but could used some informative tutorials for proper workflow. For example, in the Lunar Rover sample, there are lines emanating from the model, then text windows appear. Would I need to create all these extras inside Reality Composer Pro? I’d like to start creating immersive, narrative experiences (both in a volume, and fully immersive) but for prototyping, I want to learn the proper way to add this type of functionality. I think I remember seeing something to do with “schemas” involved. I’m assuming there might be some coding to setup in RCP for when items are selected, then an associated animation is triggered. Can anyone point me towards the relevant documentation to help me get started? Remember, I don’t code. ;) Here are my recent Vision Pro experimentations. https://youtube.com/playlist?list=PLCH753rZ9r6eqXxpIemaSlcyYxjFgR210&si=P_7AY2aL97Upm61i I’m also proficient with Unreal Engine, but getting content packaged and over to AVP is still not ready for prime time, so i’m exploring the native approach. Thanks for helping point me in the right direction!

What is recommended best practice for importing a Blender 3D file into RCP? I assume as a .usdz file? Is there a WWDC24 session or other Apple resource that best explains this. I want to make sure I provide the right format/file to RCP from Blender.

I am currently developing a game that runs on VisionOS using RealityKit and Swift. I have a question regarding particle emitters. It seems that there is a sorting order (render queue) between particle emitters themselves, but there doesn’t appear to be a render queue between particle emitters and regular model entities. If such a feature exists, could you please provide a simple example? Thank you!

Hi, every one! I'm trying to bind timeline(animation + audio) and behaviors on an entity in reality composer pro. In xcode, I need to clone this entity and use the behavior, but I found that the behaviors are not clone(send notification but not received by reality composer pro and not execute the timeline). How can I solve this problem? Thanks!

Hi everyone, I’m working on a project in Reality Composer Pro, and I’ve encountered an issue with vertex animations. Here’s what I’ve done: I created a model in Blender, which includes two animations: One that scales the vertices of the model. Another that moves the model's position. I imported both animations into Reality Composer Pro, and the position animation works fine, but the vertex scaling animation does not seem to work. What I’m Trying to Achieve: I want the vertex scaling animation to play correctly in Reality Composer Pro alongside the movement animation. Problem: The position animation works as expected, but the vertex scaling animation does not work when applied in Reality Composer Pro. I have checked the vertex scaling animation in other software, and it works fine there. The issue seems to be specific to Reality Composer Pro. Is vertex animation scaling supported in Reality Composer Pro? If so, what might be causing this issue? Any advice or solutions would be greatly appreciated!

Does anyone have any idea if Apple plans to add in UDIM support for its 3D development? It is a real bummer to not have this feature and makes an otherwise clean USD pipeline kinda suck.

I want to render a 3d/stereoscopic video in an Apple Vision Pro window using RealityKit/RealityView. The video is a left-right stereo. The straight forward approach would be to spawn a quad, and give it a custom Shader Graph material, which has a CameraIndexSwitch. The CameraIndexSwitch chooses between the right texture vs the left texture. https://i.sstatic.net/XawqjNcg.png The issue I have here is that I have to extract the video frames from my AVSampleBufferVideoRenderer. This should work ok, but not if I'm playing FairPlay content. So, my question is, how to render stereo FairPlay videos in a SwiftUI RealityView?

Hi I'm trying to create a water shader using the shader graph in Reality Composer Pro, but quite a few of the features you would need for realistic water rendering appear to be missing. One big issue is the lack of a way to create refraction. We can easily control the transparency of the water by changing the opacity, but how can we distort what we see through the water? I can't find any obvious solution for that. In Unity, they provide a node called HD Scene Color which is basically the scene rendered to an offscreen buffer which you can apply to the water and then distort to get a refraction effect. I guess the Background Blur node could be used for something like this if we could turn off the blur and distort it, but there's no control for the blur and no control for the texture coordinates. Am I missing something? Any ideas are welcome :)

Trying to add a Reality Composer Pro project into my swift playground application. Can't figure out what name to call for the package.

Hi Apple engineers, I'm currently working on an app that uses the incoming microphone audio and gives visual feedback to the user about the incoming audio. I would like to use Reality Composer Pro's Developer Capture to get a high quality recording of the app and its use cases for the App Store — but any time I have an in-progress capture, my app stops receiving the incoming audio. It almost seems as if the microphone audio is getting 'hijacked' during the screen capture, which prevents me from demonstrating the app's core features. Could you please advise on how to proceed?

If I place the .usdz file in the project directory alongside other .swift files, ModelEntity loads it perfectly. However, if I try to load the same file from Reality Composer Pro under RealityKitContent.rkassets, I get the error: resourceNotFound("heart"). Could someone help me with this? Thank you so much Code: // // TestttttttApp.swift // Testtttttt // // Created by Zhendong Chen on 2/17/25. // import SwiftUI @main struct TestttttttApp: App { var body: some Scene { WindowGroup { ContentView() } .windowStyle(.volumetric) } } // // ContentView.swift // Testtttttt // // Created by Zhendong Chen on 2/17/25. // import SwiftUI import RealityKit import RealityKitContent struct ContentView: View { @State private var enlarge = false var body: some View { RealityView { content in do { // MARK: Work let scene = try await ModelEntity(named: "heart") content.add(scene) // MARK: Doesn't work // let scene = try await ModelEntity(named: "heart", in: realityKitContentBundle) // content.add(scene) } catch { print(error) } } } } #Preview(windowStyle: .volumetric) { ContentView() }

Using Unity to develop VisionOS program, pressing the right knob of VisionPro during use will exit the Unity space and destroy the model in the space. The model in the space has been disconnected from the SwiftUI interface. After clicking the right knob, return to the system main interface, and then click the right knob again to return to the inside of the program. However, Unity space cannot be restored, and calling the discisWindow method on the SwiftUI interface has no effect, so the interface cannot be destroyed. Is there any solution??

is it possible to dynamically update ModelPositionOffset of GeometryModifier with a depth map image? in my code I set up the parameter for "DepthMapTexture" universal input node and tried setting the depth map for depthTextureResource. I have 2 DrawableQueues. One for setting InputTexture, and one for setting DepthMapTexture. This only shows the part that concerns setting DepthMapTexture this is where I define the plane entity. and this is the shader graph what I noticed with GeometryModifier is that, the depthMap image has to be same as input image's dimensions. and when I applied this material to usdz file, with pre-assigned image and depth map from RCP, and loaded that Entity from code, depth map was applied correctly. what I am unsure is that if it is impossible to define a model entity from code, apply ShaderGraphMaterial from RCP, and dynamically update the image used in GeometryModifier. Maybe I'm missing something when defining Entity, something that allows geometric modifications?

I need help to wrap my head around this... If I import the Reality Composer Pro package and load it into an ARView, I will see 1.3gb of memory usage and about 180-220% cpu usage. The frames will start at around 60fps, and then eventually drop to around 30fps. If I export the usdz from Reality Composer Pro and load that into the same ARView, I will see about 1gb of memory usage and around 150% cpu usage; fps holds longer at 60 but eventually drops. If I load that same usdz into a QuickLook view, I will see about 55mb of memory usage, 9-11% cpu, and the frames stay locked at 116fps. The only thing I notice is the button I have is slightly less responsive, but it all still works fine. I don't understand. How can I make the ARView work as efficiently as QuickLook?

We have a project which is currently being built as a XCFramework. The framework contains a custom component to be used with entities in Reality Composer Pro. I have tried to se set the RCP Package.swift file to reference the framework package for the in the dependancies. Nothing that I do with the folder path to reference the code is working. Do I need to change the project to be using Swift source code instead of a XCFramework? The component needs to be in the framework as there is a class in the framework that works directly with the custom compoent. I am able to reference the XCFramework as a Swift Package with other projects.

Hi, I am trying to create a simple effect to create feather edges on the image using Reality Composer Pro. Something like this: As you can see it has softer edges on all sides that dissolves into transparency with the background. this is what I have been able to achieve on my own. I want to use the "feather" input node value (float) from 0.0 to 1.0 to increase or decrease the strength of the feather edges.

I want to select a sub model under a large model in a mixed space, and when I select this sub model, I will add a stroke to it, similar to the effect of selecting a model in Reality Composer Pro ，How to create entity strokes similar to this effect
