This is a basic material for use with curves only for a fur or hair look. This material uses a special normal with the diffuse and specular to give a tubular look to non-dimensional curves.

Parameters

Surface

Diffuse Intensity	A multiplier for the hair diffuse contribution to the material.
Base Color	A global tint which is used for the entire hair. This color is multiplied with the Hair Color.
Hair Color	This is a ramp type parameter which is used to color the hairs from root to tip. The left side of the ramp represents the color at the root of the hair, while the right side of the ramp represents the color at the tip of the hair. By default many of the ramp controls are hidden, but can be revealed by clicking on the arrow at the bottom left of the ramp interface.

Specular

Specular Intensity	A multiplier for the specular contribution to the hair.
Specular Color	This is a ramp type parameter which is used to affect the specular color of the hairs from root to tip. The left side of the ramp represents the color at the root of the hair, while the right side of the ramp represents the color at the tip of the hair. By default many of the ramp controls are hidden, but can be revealed by clicking on the arrow at the bottom left of the ramp interface.
Roughness	This value controls the size or spread of the specular highlight along the hair.

Opacity

Opacity	This is the global opacity for the hair. Defaults to white, or opaque.
Opacity Ramp	This is a ramp type parameter which is used to affect the opacity of the hairs from root to tip. The left side of the ramp represents the opacity at the root of the hair, while the right side of the ramp represents the opacity at the tip of the hair. By default many of the ramp controls are hidden, but can be revealed by clicking on the arrow at the bottom left of the ramp interface.

White Hairs

Use White Hairs	Toggles the use of White Hairs in the material. Note that even if this is enabled, the `whitehair` attribute must be present in the fur object or fur procedural in order for white hairs to appear in renders.
Color	If White Hairs exist in the fur object (controlled with a `whitehair` attribute in the fur object and fur procedural), and if Use White Hairs is enabled; this is the color that the white hairs will be shaded.

Guard Hairs

Use Guard Hairs	Toggles the use of Guard Hairs in the material. Note that even if this is enabled, the `guardhair` attribute must be present in the fur object or fur procedural in order for guard hairs to appear in renders.
Tint Color	If Guard Hairs exist in the fur object (controlled with a `guardhair` attribute in the fur object and fur procedural), and if Use Guard Hairs is enabled; the guard hairs will be tinted with this color.
Opacity	If Guard Hairs exist in the fur object (controlled with a `guardhair` attribute in the fur object and fur procedural), and if Use Guard Hairs is enabled; the guard hairs will be multiplied by this opacity.
