Hopefully I'm missing something simple.
I'd like to create a bunch of points in a SOP network, tag them with string attributes and then import them into LOPs as transforms. I'd then like to use that string data later in a SOP Modify node to drive updated transforms. In my test I'm able to create the attributes that then come into USD as primvars, but when the USD is brought into a SOP network, the string attributes exist but are empty. Any float attributes seem to import correctly though.
Any idea why the string attrs don't work? See attached HIP.
Cheers,
Jon
