Hair Settings

The Cycles Hair Settings, under the particle tab, are used to control each hair particle system’s strand properties.

Shape
A shape parameter that controls the transition in thickness between the root and tip. Negative values make the primitive rounded more towards the top, the value of zero gives makes the primitive linear, and positive values makes the primitive rounded more towards the bottom.

Thickness

Root
Multiplier of the hair width at the root.
Tip
Multiplier of the hair width at the tip.
Scaling
Multiplier for the Root and Tip values. This can be used to change the thickness of the hair.
Close tip
Sets the thickness at the tip to zero, even when using a non-zero tip multiplier.
