Sementic Type on face in a mesh prim

Is there an approch to set semantic types of different faces in a mesh prim, instead of the whole prim?
I’d like to generate segmentation map like facial parsing via Replicator.

Thanks for reading this :)

Hello @AlanHuang! Great question and a great candidate for a new tutorial. Unfortunately, we’ve discovered that GeomSubset segmentation is broken in current releases and are working to provide a fix ASAP for the upcoming release updates.
