Hi there, I am happy to have found Reality Composer. As I continue to create content, I have run into some issues. When exporting my model into .OBJ format to upload to the composer, I notice that the objects are not solid. I have gone through the exporting process to make sure that they are, but when viewed in Reality Composer, the closest surfaces are not showing and the object looks see-through. Any idea of what is going on?

Hi, I,m trying to open a gltf file in Reality Converter and the textures maps like this: When I import as fbx the texture mapping is right. (but unfortunately the model get bad) Any one who gives a clue what's going on?

Hi, I've downloaded these things but I can't seem to import FBX file to reality converter FBX SDK 2020.2.1 Clang (Universal Binary) FBX SDK 2020.2.1 Python FBX SDK 2020.3.1 Python Bindings I'm using MacBook m1 pro

I'm loading a .usdz file into my View and so far it works fine, except from the fact that when I load multiple objects into my scene the app crashes with message: Terminated due to memory issue. I'm using Apple's default .usdz samples. It works with up to 8-10 instances and then crashes.

Having an ability to change the level of the scene plane or anchor plan on the fly would result in a much better user experience.

Hi, In our workflow, we have 3D objects with the type of gltf provided to the iOS via API endpoints. Using a different types of files is not an option here. Inside the iOS, the glb file is converted to a scn file using a third-party framework. The nodes in the converted scn file look as expected and similar to the original glb file. In the second step, the scn file should be converted to a USDZ file to use in RealityKit. As far as I know, there is only one way to convert scn to USDZ inside the iOS app. which is using an undocumented approach ( assign a usdz format to URL and using write(to:options:delegate:progressHandler:)) let path = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] .appendingPathComponent("model.usdz") sceneView.scene.write(to: path) In the converted USDZ file, all the one-sided materials (transparent) materials are changed to a not transparent material. We tested on a car object, and all the window glasses became not transparent after converting. On the other hand, if we use the Reality converter app in macOS to convert glb file directly to USDZ file, every node converts as expected, and it works so fine. Is there any workaround to fix that issue? Or any upcoming update to let us use glb file in the app or successfully convert it to USDZ inside the iOS app? Thanks

I am trying to convert gltf to usdz via usdz converter ,but there are something went wrong."An unexpected error occurred while converting this file to USDZ."Has anybody know how to fix it, I'll be much appreciated!

Hi all, I have a requirement about converting usdz to iges file in swift app, I searched on google but didn't find any support library in this. do you know a library that supports this? Thanks all.

Hello, is there a way to import 3d hat objects and have it anchored to head? Using face anchor only seems to anchor to the front of face, no matter how I position it. Thanks in advance.

I haven't been able to find anything online about this, but is there a way to convert a .usdz file or .usd file to some other easily parse-able file type (like json, xml, etc) in order to store this data in a SQL database? Anything info is helpful, thanks!

Hello I am trying to figure out what I am doing wrong. I am trying to import audio into the .usdz file, followed the "usdzaudioimport -h" with the params, and I am getting this   "Error: unexpected parameter -auralMode for argument --audio" ?? I removed it( then getting the you need parameters), used only one parameter still getting unexpected parameter or for auralMode or playbackMode!? downloaded the latest 3 times, reinstall/verified Python version and installation, the PATH, etc... It is driving nuts, being the first time I use this tool. I am hoping someone smarter than me can "slap me behind the head" and point out the obvious that I cannot see!! LOL Here is my command, any hint and things to try will be more than welcome. Thank you very much! here the command I used and the result: % usdzaudioimport /Users/macuser/Documents/griffon_v2.usdz /Users/macuser/Documents/griffon_v2b.usdz --audio /Users/macuser/Documents/CH-146_Griffon_webAr.mp3 -auralMode spatial -playbackMode onceFromStart usdzaudioimport 0.01   Error: unexpected parameter -auralMode for argument --audio For more information, run "usdzaudioimport -h"

When trying to convert FBX files... and this is not the typical FBX error because I've installed every version of FBX Python SDK, Bindings, etc.. I originally had seen that issue before but got it fixed and Reality Converter was working great for a while. An OBJ and USDC file were both converted with no issues, however when I feed it an FBX... I get the message: "Service Connection Error. Couldn't communicate with a helper application. Conversion Failed." It's been a while since I've used it and now it's no longer working on either computer. I've got the Beta 4 Version 1.0 (47.1) installed on both machines. Anyone else encounter this issue? Reality Converter Beta 4 Version 1.0 (47.1) Python: 2.7.18, 3.10.5, 3.7.0, 3.7.9 FBX SDK: 2019.5, 2020.0.1, 2020.2 FBX Extensions SDK: 2019.5, 2020.0.1 FBX Python Bindings 2020.0.1 FBX Python SDK: 2019.5, 2020.0.1, 2020.2 Computers MacBook Pro (16-inch, 2021) M1 Pro OSX 12.4 iMac (Retina 5K, 27-inch, 2019) OSX 12.3.1 Console Keeps repeatedly spitting these errors out once I launch Reality Converter.

Any tips would be appreciated. I'm eager to save time by using this great drag n drop utility. I've spent a lot of time researching this and have not found anyone with the same issue. I've tried getting the command line tool to work but that has also been having many issues. EDIT: I've ran it again and found a few lines in Console that look interesting...

I have to make 80 3D models every day. this takes a lot of time. It is so comfortable if I could make multiple 3D models with one execution because all models become made while I am sleeping. Is there a way? If so, please tell me how.

When I import the robot.fbx file into reality converter found in the Apple developer documentation found here: https://developer.apple.com/sample-code/ar/Biped-Robot.zip If I bring the .fbx version into RealityConverter, export it to USDZ and bring the USDZ file into Xcode 12 beta or any version below, the usdz robot character loses its skin bindings and the mesh has no skeleton attached. Has anyone experienced this? Have you been able to successfully convert an FBX rigged model to an USDZ model with all bones connected? I have tried this using Reality Converter beta 3 I did not edit the FBX robot character provided with Apples documentation sample.

Hello USD team, Thanks for the great demo USD and Hydra/Storm demo! Is it possible to build an app with USD Hydra/Storm -> SwiftUI interactions? Ex: a car configurator that has: a car as a USD file animations desired on the USD file. SwiftUI button to opens the doors, another button to play a sound, etc? everything rendered in Hydra/Storm. as the demo app Thanks.

Hello, I have a problem with converting GlTF to USDZ using usdzconverter. After converting, the resulted USDZ file has a displaced axis of rotation, when the original axis is placed in the center of the object. I've attached two screenshots, in the first one axis is correct (the file was converted with a third-party service) and in another one it's not (usdzconverter was used) Is there a way to fix it somehow? Thanks, Mikola

Just updated to Monterey 12.3 and Reality Converter shows error message when dragging and dropping obj (it worked fine before in 12.2.1) Any help would be greatly appreciated

Does Apple have any documentation on using Reality Converter to convert FBX to USDZ on an M1 Max? I'm trying to convert an .fbx file to USDZ with Apple's Reality Converter on an M1 Mac (macOS 12.3 Beta), but everything I've tried so far has failed. When I try to convert .fbx files on my Intel-based iMac Pro, it succeeds. Following some advice on these forums, I tried to install all packages from Autodesk https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2020-0 FBX SDK 2020.0.1 Clang FBX Python SDK Mac FBX SDK 2020.0.1 Python Mac FBX Extensions SDK 2020.0.1 Mac Still no joy. I have a work around - I still have my Intel-based iMac. But I'd like to switch over to my M1 Mac for all my development. Any pointers? Note: I couldn't get the usdzconvert command line tool to work on my M1 Mac either. /usr/bin/python isn't there.

How can I crop a 3D model as seen in the photos? Should I use MetalKit or can I handle it with sceneKit and modelIO? I couldn't find any code examples on this topic. Can you share the code snippet Before: [https://i.stack.imgur.com/yDXXF.jpg) After: [https://i.stack.imgur.com/m9ryg.jpg)
