Hi, I was wondering if anymore insight has gained regarding this matter. I’ve tried all of the above but can’t get rid of the splinter geometry.

Hi Wessel, I saw your post on C4Dcafé too :-) I'm struggling with how to create those selection sets when exporting the alembic file. I have a group of scattered objects and it imports with only one selection set for all geo, would like to texture the objects individually. Any hints? Thanks.
