Hi, So I created a scene in Reality Composer but when trying to export to USDZ, all of the animations, audio and interactions work, but the textures have been completely changed... (Map should be green, for example) Everything looks fine in Reality Composer Unfortunately, exporting as a .reality file isnt an option in this project. Could I get some insight into this please? Thank you

Dear community, I downloaded the USDPython 0.64 Package for my macOS Big Sur 11 on my new Mac book pro with M1 (13inc). After installing it the .pkg ( that is a modelio) I open the folder in my Applications folder and I double click on the usd.command. I am on .zsh and I did .zshrc and inserted my filepath in my case are export PATH=$PATH:/Users/<myusername>/Applications/usdpython/USD export PYTHONPATH=$PYTHONPATH:/Users/<myusername>/Applications/usdpython/USD/lib/python export PATH=$PATH:/Users/<myusername>/Applications/usdpython/usdzconvert are these correct? I am not sure if that Machintosh HD should be /Users/<myusername> I keep getting the Error: failed to import pxr module. Please add path to USD Python bindings to your PYTHONPATH Any help would be much appreciated

Hello, My problem is that I would like to have the first screen (the screen right before entering AR) removed from the AR Quick look. I want it to where when I open the USDZ, it goes straight into AR, and not show the screen before it, similar to how Apple does it when you want to view their iPhone 13 pro in AR.

I want to remove unnecessary materials or textures in order to reduce the size of the USDZ model I have. How can I manipulate this model with swift? or, I can try any advice to reduce the size of the USDZ model

Is there any way to download apple product models in .usdz directly from apple website?

I am using scene.write(to:"dirpath\name.usdz") to get usdz export functionality into my app (universal, macOS & iOS). My problem is, it ceases to work after the first use, quitting & restarting the app is the only way to re-enable it. I have tried reusing the same scene, and instantiating a new scene (both ways with the exact same node structure), same results every time: first invocation writes a file of ~14MB, any calls after that write 1.5-2k of garbage. I use a unique filename for each write, and check to make sure it doesn't already exist. Any ideas?

I've been watching a 2019 Developer Video "Building Apps with RealityKit" and working along with it. It shows how to create a custom entity. It shows how to load entities from .usd files. How do you either load a custom entity, convert an Entity to a custom entity, or maybe move model hierarchy from an Entity to a custom entity? I assume there's a way to do this.

Hi, I'm using the provided CaptureSample together with HelloPhotogrammetry to create a 3D model. Although I am making sure that there are depth images within the folder (TIF) - after building the model, the model size is tiny. How can I make sure that the model is built in the real world size? or - how can i resize the model to real world size? Thanks.

Hello, I have a gltf file, which I am converting to usdz using threejs online editor. The file is a sofa model, with all its maps baked to complete UV except diffuse fabric map which is tileable to emulate a fabric cloth. So the fabric map has to use an increased scale of 17 so it tiles properly, but the other maps dont need tiling and work on the 1scale value. The problem I am facing is that the Quicklook uses scale of diffuse fabric map and applies on all others as well, distorting the look. how can I control this? i am a windows user. thanks

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

Hello friends, Im using Terminal to convert .glb file to .usdz file with USDPython-0.65 which I download from Apple developer website. I was using usd command properly since yesterday. Im getting this errors. https://ibb.co/PDmB3qn Anybody having this trouble too?

I am trying to build a website where I would like to render the USDZ 3D model on the browser without the AR feature. The user should be able to interact with the 3D model using a pointing device (mouse). If the user wants to see the 3D model in AR she/he can do so by loading the page on a compatible device where the 3D model can be projected in AR. I am looking for an answer to how to display the USDZ 3D model on the browser without the AR feature.

Nevermind, will be using https://github.com/Shopify/screenshot-glb

Hi everyone, is there a way to convert programmatically a RealityKit ModelEntity in a Collada format (.dae) or better glTF? I'm able to find converter COLLADA -> GLTF but not USDZ -> GLTF and using Photogrammetry the only possible output is USDZ, but it's not globally available. Thanks a lot, any input is welcome. Regards, Mirko
