Incorrect transform when exporting complex object hierarchy to USD

[peterhorvath111]

Continuation of #1402.

Exporting a more complex object hierarchy, like the figure scene in the referenced ticket, is still broken.

Repro: https://github.com/user-attachments/files/18905186/figure_scene_ass.zip
Resave to USD (kick scene.ass -resave scene.usd) and render.
