Editing Smart Hair Mesh

If the look of the smart hair mesh is not ideal, then the mesh of the hair can be edited.

1. Create a character.
   
2. Apply a hair template or create a custom hair, in this case, eyebrows.
   
3. Select the hair, click the Edit Mesh button in the Modify panel.
   
4. Edit the meshes with the available tools.
   
5. Exit the editing mode after the modification is complete.
   
   However, when the character assume facial expressions, the hair may experience faulty displacement caused by the offset of the eyebrows from the skin weights. This can be fixed with skin weight reassignment.
   
6. Make sure the hair is selected. In the Attribute tab of the Modify panel, click the Create Facial Hair button to re-assign the skin weight to the hair.
   
7. Select the proper preset from the panel, in this case, the Brow.
   
8. Produce facial expressions for the character and the skin weight is correct assigned to the hair mesh.
   
   Note:

   If the stretching issue remains, then you need to Re-assign Smart Hair Skin Weight for the hair.
