I'm working on a project wherein RealityKit for iOS will be used to display 3D files (USDZ) in a real-world environment. The model will also need to animate differently depending on which button is pressed. When using models that are downloaded from various websites or via Apple QuickLook, the code functions well. I can hold the animation in place and click a button to play it.
Unfortunately, although the model (through blender) my team provided is animating in SceneKit, it does not play at all when left in the real world, not even when a button is pressed.
I checked RealityKit USDZ tool, and found usdz file is not valid, they are not figure out whats wrong.
Could you please help me figure out what's wrong with my USDZ file?

We are porting a iOS Unity AR app to native visionOS.
Ideally, we want to re-use our AR models in both applications. These AR models are rather simple. But still, converting them manually would be time-consuming, especially when it gets to the shaders.
Is anyone aware of any attempts to write conversion tools for this? Maybe in other ecosystems like Godot or Unreal, where folks also want to convert the proprietary Unity format to something else?
I've seen there's an FBX converter, but this would not care for shaders or particles.
I am basically looking for something like the Polyspatial-internal conversion tools, but without the heavy weight of all the rest of Unity. Alternatively, is there a way to export a Unity project to visionOS and then just take the models out of the Xcode project?
I'm trying to make a simple demo of using ShaderGraphMaterial in a USDZ file that I can preview on Mac and VisionOS but I'm having trouble.
In Reality Composer, I make a sphere, then assign a ShaderGraphMaterial to the material, with a simple diffuse color (green) input. When I save the file as .usda, it displays as a gray sphere on mac rather than the green sphere shown in reality composer. If I then convert to usdz using Reality Converter, I get a warning on import:
"Shader nodes must have “id” as the implementationSource, with id values that begin with “Usd”. Also, shader inputs with connections must each have a single, valid connection source."
And the exported .usdz also shows as a gray sphere.
Is there a simple demo of a .usda file using ShaderGraphMaterial that displays on Mac, iOS, and VisionOS that I can look at to see how it looks internally?
My actual problem is creating usdz / usda files on visionOS for viewing on iOS / Mac / VisionOS.. but the first step is showing it's possible to even use ShaderGraphMaterial across all platforms.
Thanks

I've got a couple 2D PNG assets that I want to add to a scene made of a couple other udsz files in RCP (picture adding a couple 2D videogame characters to a simple 3D diorama).
When I try to drag the PNGs to the workspace or the file tree…nothing happens.
I found a walkthrough on Medium (called "Importing and Exporting Personalized Objects for Augmented Reality: Reality Composer and SwiftUI" for those curious as I can't link to Medium posts here) that makes it look like users could do this with simple drag-and-drop. The Medium post is from June 2023, and in the screenshots RCP visually looks a lot more like Reality Composer on iPad, so I'm assuming it's changed a lot since then?
Is there still a way to do this? I've tried adding the 2D elements to a scene with Blenders "import images as planes," but I'm getting weird halos around them and was hoping RCP could make the process a bit easier/cleaner.

I’d like to convert a Filemaker 18 Runtime to a Mac (Catalina) application package.
I found a youtube video that describes how to convert a shell script into a Mac OSX App.
This is the shell script:
I’ve had no luck adapting it to convert my Filemaker runtime into an app.
Thanks in advance for any advice.

Lara
