Hi guys, I have set size of cube is 20 cm. Then i want to transform scale with values x: 0.048, y: 1, z: 0.0.48, But strangely it reset all value to x: 1, y: 1, and z:1. Then i want to try with another decimal such as x: 1.2, y: 2, z: 1.2 the panel will automatically reset it into x: 1, y: 1, z: 1. My question is how to set transform scale that can accept decimal number ?

I am trying to add a picture and a video into my USDZ model to be shown in the final exported USDZ file. Any pointers on how to do that?

I’m having issues getting Collision Shapes working in Reality Composer on iPadOS, or with Reality Composer Pro via Xcode on macOS? I’ve posted a video recorded through my Vision Pro showing the issue. The project i’m working on is a Dice Rolling application. The dice don’t appear to be working set as Collision Shape=Automatic, which I assume takes into account the actual silhouette of the shape. https://youtu.be/upPtQY4QOAk?si=yyx6rbSSmVkLxBLg They also don’t rest on their face when they land. Anyone experience this type of behavior and found a solution? I’m currently doing this with Reality Composer, but most likely will also be wanting to get it to work properly in Reality Composer Pro as well. Thx!

Hi everyone, I’m having trouble with image anchoring when working on a project in Reality Composer and Reality Composer Pro. Here’s the issue: 1. What I’m Trying to Achieve: I want to create an AR scene where an object anchors to an image I provide. I don't want to create an app for this but just use the USDZ File the Scene creates. The USDZ File then should be viewable via the various integrations of AR Quick Look across the Apple Ecosystem. The image anchoring works perfectly when I preview the scene inside Reality Composer using AR mode. 2. The Problem: When I export the project (tried both USDZ and Reality formats) and open it on my iPhone using the Files app (which uses AR Quick Look), the image anchoring no longer works. The object doesn’t anchor to the provided image as expected. It just anchors to the first plane it recognizes and not the image. 3. What I’ve Tried: Exporting the scene in USDZ format. Exporting the scene in Reality format. Both formats result in the same issue: no image anchoring outside of the Reality Composer environment. Trying different images but all resulting in same manor that the image anchoring is not working Tried different iOS Version but resulting in the same issue 4. Current Setup: Reality Composer Pro version: 2.0 iPhone model: iPhone 13 Pro iOS version: 18.1. 5. What I Need Help With: Is there a way to ensure image anchoring works in exported files when opened via AR Quick Look? Do I need to configure something specific during the export process? Are there limitations in AR Quick Look that prevent image anchoring from functioning correctly? Do i need to create an app to make this work? I’d appreciate any advice or insights from the community. If anyone has experience with similar issues or knows of a workaround, please let me know! Thanks in advance, Mav

I have created a simple scene in reality composer (composer not composer pro). It contains just a cube and text item. I convert this to usdz file and load it into a Arkit swift app. Since ios 18/xcode 16 - the "text" element is not displayed at all. The cube is displayed, anchors correctly and can be moved etc....

Ever since updating to Xcode 16 my AR app doesn't compile, because Xcode doesn't recognize the .rcproject files used to load the AR experiences in iOS app. The .rcproject files were authored in Reality Composer on iPadOS. The expected behavior is described in this official Apple documentation article: https://developer.apple.com/documentation/realitykit/loading-entities-from-a-file How do I submit a ticket to Apple?

I've just updated to macOS 15.2 Beta and Xcode 16.2 Beta and just noticed I can't build my visionOS app as before. I have a separate /Volumes/Development APFS volume for Xcode projects, plus utilising a Relative setting for DerivedData so that these are located in the projects' directories – in this case, subfolder on this volume mentioned. I just found that when attempting to build the app in either Xcode 16.1 or 16.2 Beta with visionOS 2.1 SDK, I'm getting a following error: Finished processSwiftFiles() with a failure 'You don’t have permission to save the file “CustomComponentUSDInitializers.usda” in the folder “RealityAssetsGenerated”.' Sandbox: realitytool(6216) deny(1) file-write-create /Volumes/Development/travel-visionos/DerivedData/Tripomatic/Build/Intermediates.noindex/RealityKitContent.build/Debug-xrsimulator/RealityKitContent_RealityKitContent.build/DerivedSources/RealityAssetsGenerated/CustomComponentUSDInitializers.usda.sb-02874eb3-PS4qfZ Failure creating schema - 'You don’t have permission to save the file “CustomComponentUSDInitializers.usda” in the folder “RealityAssetsGenerated”.' This for sure worked previously with 15.0/16.0 or 15.1/16.1 as I've even published the app to the App Store. It seems to be some shenanigans related to sandboxing &amp; permissions for Xcode tools which I can hardly work around. I have Xcode added to Developer Tools and Full disk access sections in Privacy &amp; Security, yet that doesn't really change anything in relation to this issue. When I move the project to a subfolder in my home directory, the build succeeds. The same applies to switching DerivedData setting to the default value to that DD are generated in ~/Library/Developer folder for all projects opened in Xcode. Thus, either macOS or Xcode now has an issue with running realitytool to generate files on my dedicated volume. Should I consider this Xcode or macOS Beta issue? Report it via Feedback Assistant maybe?

As you can see, it is a transparent spherical shell model with a ball inside. Everything is normal on the front side, but there are strange mesh triangles on the side and back view. I don't know if this is as expected and what I need to do to remove these strange effects.

After upgrading to Xcode 16 my app, which utilizes imported project files from my iPad's Reality Composer app, now has two issues that I have found so far. I am using an ARView as a UIViewRepresentable with SwiftUI. (Prior to upgading to Xcode 16 everything worked well.) First, there are now several duplicate rcp_export.usdz resources in the "Copy Bundle Resources" build phase section. Even though each file is in a separate folder with a unique UUID, it was causing a compile error saying there are duplicate files. I was able to open the RC project folder and delete the older rcp_project versions which now allows the app to compile. I mention it as it may or may not be related to the second issue. Second, Xcode isn't generating the project code for rcproject, so when I call the RCProject.loadSceneAsync function I am getting an error that says "Cannot find 'RCProject' in scope"

In RealityKit, I know that an HDR image is pre-calculated, and through the settings of the ImageBasedLight Component, a specified specular object can reflect the content of the HDR image. If a mirror object is originally very large, such as a large-area continuous glass door, after specifying an IBL image for these glass doors, the image reflected by the mirror will be obviously deformed when it moves in space. Because IBL is a picture of the surrounding environment at a point, while the glass door is a surface. Is there a truly real-time specular reflection calculation setup in RealityKit that can reflect the model on the opposite side of the glass door?

Using Xcode 15.4, I have successfully built and run my app using Reality Composer Pro Version 1.0 package. I then successfully submitted that app version for release. Now, using Xcode 16 Beta 6, I've created a new branch repository for updating my app for iOS/iPadOS 18 and visionOS 2. However, once I created and switched to the new branch and did a build, I get build errors. It seems to be regarding the package manifest that relates to my Reality Composer Pro package that is part of my app. When I go to the package file in my project navigator and click the Open in Reality Composer Pro button, my package opens in Reality Composer Pro 2.0, which makes sense since it it the version for Xcode 16. However, I don't know how to address/get rid of the build errors. I've added and image of my build errors.

Hello, I downloaded the most recent Xcode 16.0 beta 6 along with the example project located here Currently I am experiencing the following build failures: RealityAssetsCompile ... error: [xrsimulator] Component Compatibility: BlendShapeWeights not available for 'xros 1.0', please update 'platforms' array in Package.swift 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] Exception thrown during compile: compileFailedBecause(reason: "compatibility faults") error: Tool exited with code 1 I saw that there is a similar issue reported. As a test I downloaded that project compiled as expected.

I have design a 3D object and exported it as a USDZ. I also 3D printed said object. I want to use the object as a 3D trigger for an AR experience I am building. My question is: is there a process that would let me take the 3D .usdz file and convert it to a .arobject or a .objcap medium/low density point cloud to use as an AR trigger. Because I do have the 3D print of the object I did use the "scan" option when setting up my scene but the "resolution"/fidelity seems really low, and the results I get are just mediocre. I would love to take my 3D USDZ that I already have and use it to generate a file that can be used as a 3D trigger. is this possible, or is there a process to do this. I am able to take the 3D that I scan in Reality Composer (which is exported as a .objcap file), send it to reality converter on my Mac and make a USDZ from it. I am looking for a way to go the other way .USDZ > .objcap or .arobject. I am trying to make a experience that mimic projection mapping but in AR. I have a 3D object I built and textured in substance painter. I also printed this object in a base gray color. I want to use the 3D print of the object as an AR trigger that would start a scene placing/overlaying/projection mapping the textured 3D model over the gray 3D printed model. Ideally the mapped 3D model would be spatial attached to the 3D print and move with it when the object is handled.

The object capture feature in Reality Composer App is only available in iOS and iPadOS at the moment, would this feature be available for visionOS in near future? Reality Composer App Store https://apps.apple.com/us/app/reality-composer/id1462358802

I can‘t Figure Out How to Get My Earth Entity to Rotate on its Axis. This is a follow up post from a previous Apple Developer forum post. How would I have the earth (parent) entity rotate CCW underneath the orbiting starship child? I tried adding the following code block to the RealityView but it is not working: if let rotatingEarth = starshipEntity.findEntity(named: "Earth") { rotatingEarth.transform.rotation = simd_quatf.init(angle: 360, axis: SIMD3(x: 0, y: 1, z: 0)) if let animation = try? AnimationResource.generate(with: rotatingEarth as! AnimationDefinition) { rotatingEarth.playAnimation(animation) } } Any advice on getting the earth to rotate? I tried reviewing the Hello World WWDC23 project code, but I was unable to understand the complexity and how that sample project got the earth to rotate. i want to do this for visionOS 1.2. I realize there are some new animation and possible other capabilities coming up in vision 2.0 but I want to try to address this issue in the current released visionOS version.

Hey, is there a way to create a good ground shadow shader? I'm using a ground with an unlit material and I can't get the ground shadow to work properly. If I use a PBR texture it works better, but i can barely see it and I want to control the intensity more.

For all the AVP devs out there, what cloud service are you using to load content in your app that has extremely low latency? I tried using CloudKit and it did not work well at all. Latency was super bad :/ Firebase looks like the most promising at this point?? Wish Apple would create an ultra low latency cloud service for streaming high quality content such as USDZ files and scenes made in Reality Composer Pro.

The 3D object capture feature doesn’t seem to work on my iphone 12 pro. The circle that is supposed to show up when you begin to begin to move around the object doesnt show up so object capture doesn’t even begin. It says ‘more light..’ or ‘move closer’ but this doesnt happen on my iphone 14 pro. Works perfectly fine on that even with the same lighting. How can this be fixed?

Hi I installed Xcode. I found to anchor plane option which seen in Reality Composer. but in pro version, can't found. where are the options? thanks
