Rendering issue with distortion coefficients

[RenzhiWang]

Description

Rendering issue with distortion coefficients.

The process to reproduce this issue is simple

1. Import any 3d gaussian usdz file.
2. Add a camera to the stage.
3. Save.
4. Run python script to apply distortion coefficients
   python.sh /folder_to_project/scripts/camera_3dgs.py --usd /folder_to_project/assets/test.usd --camera_json /folder_to_project/scripts/camera.json

Because unable to upload asset files, I upload a zip file without assets.
