I work with Octane Render that accept Alembic files...

In the OBJ files I have some "groups".
Example: In the head.obj we have eyes, tongue, teeth ......... etc

When I import Alembic (exported fron CS ) in the Octane Render the OBJ loses all groups, thus it loses the textures, and turns into a single group.

Is this behavior a failure of ChronoSculpt ? Or Octane ??
Do you get Alembic with "groups" in another software ?

Thank you
Peace
