I'm stuck with an issue with the animation of the AR usdz file.

hi

I am working on AR development.

Development is progressing using https://github.com/ProjectDent/ARKit-CoreLocation, and development is progressing to some extent. (using ARSCNView)

In the process, we were using a file with animations using usdz, but there was a problem that the animations were working abnormally.

The example usdz provided by Apple works normally, but there is a problem in the usdz that is created and used separately.

If you use usdz as the default app provided by Apple, it works normally again.

Do I have to do something when creating the 3d file to make it work like the usdz animation provided by Apple?

We are stuck on these issues and are constantly looking for information.

I hope you get some help here.
