Hello
What is the best way to hide faces/polygons from mesh in Solaris?
Example if I want to hide the faces on a body mesh that's under cloth mesh to remove the issue of penetrations.
Would it be possible to do this on the USD file that contains the shader assignment? that's gets layered on top of an Alembic file?

AFAIK, you can't. USD does not allow changing the visibility of certain polygons on a mesh. Even with a GeomSubset it won't work. You can blast them with a SOPModify, but that will redefine the whole topology.

maybe GeomSubset with material override with 0 opacity?

When a mesh is turned into a subdiv, holeindices work. Because most characters are subdivs, that's what I've seen used in production. For meshes/polygons, displayOpacity could work, but a material applied to a geomsubset should also work.
I'm o.d.d.
