I have a glass rbd sim using rbd_disconnected_faces sop to group connected faces. In sops I then mark those faces as invisible with a visibility sop.

However in Lops this visibility group is not respected. I attempted to write out per-face "usdvisibility" but with no luck. What's the best way to hide the interior glass faces until the glass shatters and have that work in Lops?

Edit: Interestingly enough, referencing in an alembic version of the cache, works just fine.

I attempted export the usd with the group "connected_glass". I then tried both the rendergeosettings set to render visibility set none. I also tried a wrangle, and set the usd_setvisibility=0. Neither worked.

geomsubsets cannot set visibility. Only prims can have animated visibility. change the path attribute of the faces that need to be hidden so they generate a new prim. Then set the visibility there.

Smart. Thanks jmack.
