Converted USD files not opening correctly after moving directories

[Yasu31]

after converting my MJCF file to USD file (and overcoming the issues with MJCF -> USD conversion reported in #2113 and #2171), the resulting USD file loads correctly only within the original generated directory. Moving the USD file (even with all generated assets in configuratin/) to another directory or another PC corrupts the file, and the viewport is blank when loaded into IsaacSim.

When I use the USD Paths tool to check what paths the USD file is using (the tool is located in a different location from the video in https://docs.omniverse.nvidia.com/extensions/latest/ext_usd-paths.html - see screenshot below),

The USD model references many local absolute paths (this was for the ORCA hand model), which is presumably why it fails to load when the files are moved.

Solution was to use "Collect and Save As..." (https://docs.isaacsim.omniverse.nvidia.com/4.5.0/omniverse_usd/intro_to_usd.html) to make a new USD file, which will properly rewrite asset paths, ensuring they are fully self-contained and portable.

now, the USD Paths tool shows that the files are referenced with relative paths (you can see that there is one file still referenced with absolute paths, but it didn't seem to cause an issue when opening in another PC)
