Head Segmentation

Head Segmentation isolates the subject's head, allowing you to apply customized textures and effects to it.

1. Open Effect House.
2. Go to the Hierarchy panel.
3. Click the Add object button [+].
4. Go to Segmentation.
5. Select Head Segmentation.

A Segmentation material will automatically be added to the Material property of the Image component when adding a Head Segmentation object. Segmentation material is useful for quickly adding commonly used segmentation effects to the scene.
