Hair has particular unique qualities that need a dedicated material. The Corona Hair Material is physically accurate and handles the unique highlights and transmission properties that hair requires, while still rendering quickly and giving you the ease of use in controlling the material that you expect from Corona. The hair material is mainly intended for creating human hair and animal fur, as it includes properties based on natural hair model (melanin pigment amount, anisotropic reflections, hair fiber caustics); however, it can be as well used to render carpet strands, fuzzy fabrics, nylon strings, and other types of synthetic fibers.
Corona supports the native Cinema 4D Hair for generating hair geometry.

The Corona Hair Material is intended only for special hair objects. Applying it to any other objects, such as boxes, spheres, or any other geometry object will most likely result in incorrect shading on those objects.
