This shader is considered deprecated and will be removed in a future release. You should use the Standard Hair shader instead.

The Hair shader is designed to render the look of hair or fur. Note that this shader needs to be used on geometry that has been defined to look like hair or fur (for example using Arnold's curves shape node). Other shaders such as Lambert could be used, but the Hair shader has a specular shading model specifically designed for thin hair fibers and lets you define different diffuse colors for the root and tip of the hairs, for example. This shader currently uses a simple Kay-Kajiya shading model.

Further examples of customer work using the Hair shader can be found here.


The images below show the separate effect of the root, tip and specular colors. The far right image is the resulting combination of these colors.


The shader is divided into diffuse and specular tabs, more info on which can be found below.


More details of how to assign the Hair shader to Houdini fur can be found on the Rendering Fur Workflow page.
