"When using the alembic format as a geocache/xform pipeline and combining it with the reference system, we're facing a problem with the auto renaming of referenced shapes once deformed. I mean if you try to reconnect the exported alembic cache to the original hierarchy, it won't as maya have renamed the shapes to shapeDeformed. We managed to avoid it by forcing the AbcExport plugin to remove "Deformed" characters in exported shape names. Couldn't think of a better way. Also, I find it a bit constraining to be forced to connect to same namespaced object and not having kind of a search and replace namespace function."
