Nested gprims are not supported?(I used a super clean model

Hi there!

I am trying to use audio2face to generate some blendshapes for my character’s head. The lip sync function worked, but it failed to get blendshapes for me because of the error message “nested gprims are not supported”.

I was wondering how to define “nested gprim” because my model is very clean and generic.

Here is a screenshot of the error code.

In USD (and Omniverse as it’s USD based), GPrims are mesh geometries and they’re not allowed to be parented under other meshes. I’m not quite sure how this has happened in your case without looking at your scene.
