Hello,

I was wondering if anyone could share the correct workflow for face sets in alembic.

Currently I'm importing an alembic from C4D that contains polygon selection sets which are passed through the alembic. When I export the alembic back to C4D, after passing through my rig node tree, the sets are lost. Can anyone shed some light on this?

Basically I'm trying to go from C4D through Houdini and back to C4D and keep my alembic selection sets throughout the process.
Any ideas?

Could you post an example Alembic archive from C4D and a .hip file illustrating how you are attempting to re-export the data?

Just as an update,
I managed to sort it out.

I needed to pass the alembic import node through as “load houdini geo” then export using file -> export alembic, as opposed to using the alembic rop.

Hope this helps anyone with the same issue!
