Hi,

Ornatrix hair animation needs to be loaded using the Animation Cache modifier:

1. Export the hair as Ornatrix Alembic, make sure to specify the range of animated frames,
2. Import the hair back as Ornatrix Alembic. It will create a new BakedHair object,
3. Add Animation Cache modifier to the hair object just created and load the same file in it again.
