When importing an Alembic cache, you can merge the cached objects with their original Maya objects. When merged, the Alembic geometry replaces the original objects in the scene. The Alembic object's animation data is preserved and it inherits shading data from the scene object. To be merged, the Alembic objects must have the same name and object hierarchy as the source geometry. The topologies of the scene and Alembic objects do not need to match.
To inherit the shading network from the Maya geometry, the Alembic geometry must have the source object's UV information. You can export the UV map from the source geometry by turning on UV Write when exporting Alembic cache . See Create Alembic caches and Import Alembic cache files.
