USD Material Lost

i’m trying to create race track with USD form.
when i use USD in Nvidia Omniverse Nucleus server, it works well.
but after i download USD from Nucleus server (include Material folder), every material has no texture or else.

Do you import in UE with UE USD importer or with the Omniverse plugin.
Do you get any information in your logs?

here is the Messege log when i open with USD stage.

when i use Omniverse plugin and USD in added server(NUCLEUS)
there was no problem.

Can you share a USD sample with us?
