Exporting Hair to Alembic 



Exporting Ornatrix Maya hair to Alembic video tutorial

Ornatrix provides a special translator which allows writing one or more hair objects into an Alembic file. The resulting .abc files can be imported in a myriad of CG software which supports Alembic. They can also be used with V-Ray Proxy objects to quickly load and render the resulting hairs anywhere V-Ray is used. There are options to export single frame or an animation range as well as viewport or render representation of the hair.

  3. In the File(s) box click the folder icon to browse. Select your exported .abc file
  4. The hair should now be imported and appear within the viewport

Using MEL to export hair to Alembic 

In addition to exporting hair to Alembic through the UI you can also do it through scripting using MEL. The following command will export a hair object to Alembic file:
