When the USD ROP node's Save to Disk button is used, sometimes it generates sidecar USD files because there are configurelayer, sopimport, etc. nodes with their layer Save Path set.
Using Python, how can I get the paths where these would be saved?
I can't find anything in the documentation.

The $SAVEDPATHS local variable can be used in the post-render script. It evaluates to a space-separated list of all the files written out during the USD save operation. This variable does not seem to be mentioned in the documentation for some reason. I will rectify that.
