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

Computers

iMac (Retina 5K, 27-inch, 2019)
OSX 12.3.1
Console Keeps repeatedly spitting these errors out once I launch Reality Converter.
And this is before I've even dragged a file to it.
error 12:06:15.086889-0700 Reality Converter CurrentVBLDelta returned 0 for display 1 -- ignoring unreasonable value
error 12:06:15.087094-0700 Reality Converter [0x7fa90810fa20] Bad CurrentVBLDelta for display 1 is zero. defaulting to 60Hz.
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... Sandbox Issue?

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

I've tried converting a gltf to usdz but it only puts out a USDZ-conversion error. Under deatils it only says "An unexpected error occurred while converting this file to USDZ. Please fix any other errors and try again."
This error just showed up recently. I'm on MacOS 12.3.1 and Reality Converter 1.0 (47.1)

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

Any USDZ file exported from Reality Composer fails to import into Reality Converter. Every USDZ file I have exported from Composer (even just a cube with a default glossy paint finish anchored on a horizontal surface) fails on import to Converter with the message "Conversion Failed: 1 Error". I suspect that the problem is with Composer and not Converter, since USDZ files created by other means import into Converter just fine.
Steps to repro:
Enable USDZ export in Reality Composer (Preferences/Enable USDZ export)
Add a cube
Export USDZ, current scene only (although this seems to make no difference)
Open Reality Converter
Drag USDZ file from step 3 into the window
Observe error message
Better import diagnostics would be good too.
I'm currently on a research project where we are making some trees for AR experiences and I'm having some issues with the PNGs I'm using for leaves. I model the trees in a program called Tree It and then export that into Maya to convert it to a GLB with Babylon.js' Maya Plugin.
Then to test how it looks I put the tree into Babylon viewer and it looks perfect. The png transparency works fine and there is no hazy white background around the planes i'm using as leaves.
Now comes the issue. When I drop the GLB into Reality Converter the pngs suddenly have a mostly transparent but still visible white background.
It seems the issue is with Reality Converter since I don't run into this problem anywhere else in the pipeline. I vaguely remember reading something about Apple adding a faint white background to pngs but I can't remember if i just imagined that.
Anyways here is a closeup of the issue:

I used to use usdzconvert to convert my .obj files to .usdz (adding the materials via command line parameters).
usdzconvert however is written in python 2, which is no longer supported in macos x 10.12.
Consequently after the latest update, I can't convert obj files to usdz anymore via command line and have to use the Reality Converter instead.
Does anybody happen to know of other ways how to convert .obj files to .usdz using the command line?
Thanks,
Christoph

Hi,
I have a problem with scaling objects. In my 3D software I have objects that scale to zero within an animation. So in the 3d software they are not visible anymore. When I export the animated geometries as fbx, load them into RealityComposer and play the animation, the objects no longer scale to zero, they just become very small. But they are still visible.
Does anyone also have this problem and does anyone know a solution?
Thanks

I have a usdz file that is viewable by quicklook and by preview, and also by my iPhone, but Reality Converter on my Macbook Pro Macos 11.6 fails to load it saying: Conversion failed: validation failed. What is wrong?
I just updated to macOS Monterey 12.3 beta (21E5196i) and I've been using Reality Converter app for a while with Blender, but after this update, somewhat this app no longer accept GLB or USDC from Blender.
This is really weird, because I need it to work.
Any idea what's going on?
