  • Export file browser known issues:

    • Double clicking on an existing usd file the exported usd will be written one directory above. Please use single click to select and then press Export button

    • Comment field does save the checkpoint comment because it is not implemented even though the UI shows it.

    • Search field does not work because is not implemented even though the UI shows it.
