I have a cloth sim, that has @10 pieces of cloth and each is assigned a point group.

I can see them throughout the sim, and I have everything checked for the alembic export.

When I brink it into C4d for lighting and rendering, I see pretty much everything but the point groups (clothID1, clothID2, etc...)

Any ideas about what I'm doing wrong?

Alembic does not support point groups. You'll have to encode them as point attributes.

Is there a node for that?

group promote can convert groups to integer attributes
