The Curl channel curls the hair by slightly rotating each segment of hair.
Curl defines the degree to which the hair should be curled. The higher the value, the curlier the hair will be. A negative value will reverse the direction of the curl.
Of course, such curls can also be created using guide styles in the Hair Tools (e.g., the Curl Tool).
Use the Variation setting to adjust the irregularity of the curl.
Use this slider to define the percentage of hair hat should be affected by Curl.
Use this setting to define which coordinate system should affect the hair. You can select from:
World coordinate system (direction is determined using the Axis setting).
Object coordinate system (direction is determined using the Axis setting).
Each hair will curl in a random direction.
The hair will curl in the direction already defined by guides for the hair curvature and waves.
If one of the coordinate systems was selected in the Direction setting, Variation will randomly vary the axis of rotation for each hair.
Use this setting to define around which axis the hair should curl. Use the Direction setting to select a coordinate system (world or local).
If you select Texture, the following will apply with regard to RGB values:
Instead of describing complex mathematical vector calculations, we will simply use the images below to demonstrate the effect different colors have on curling hair.
Use this function graph to define the strength of curl (Curl setting at top) along the entire length of the hair.
A texture loaded here will define the strength of curl (Curl setting at top) across an entire surface.
