You can import Alembic caches into a Maya scene as separate object hierarchies You can also add the cached objects to an object hierarchy that is already in the scene. When adding Alembic objects to an existing object hierarchy, you choose to parent selected geometry to the Alembic objects, or merge the Alembic objects with the original Maya geometry. See Merge Alembic and Maya geometry.
To import an Alembic cache as a separate object hierarchy
For information, see Alembic Import Options .
The Alembic objects are imported as a separate hierarchy at the root of the scene.
To import an Alembic into an existing object hierarchy
When imported the Alembic objects appear in the hierarchy under the selected scene object.
When imported, the Alembic objects and original geometry merge into a single object hierarchy.To be merged, the Alembic objects must have the same name and object hierarchy as the selected Maya geometry. See Merge Alembic and Maya geometry.
