Paint Hair Follicles Settings

Paint Modes

Select one of the following Paint Modes in the Paint Hair Follicles Settings window. To open this window, in the FX menu set, select nHair > Paint Hair Follicles > .

Create Follicles

Adds follicles to the surface as you paint. The follicles created, and their appearance, are based on the Density, Points Per hair and Hair Length settings in the Paint Hair Follicles Settings window.

To create a new hair system, select Create New from the Hair System drop-down list and then paint on the surface. To paint hair on an existing hair system, select the hair system from the Hair System drop-down list and then paint on the surface.

Create Passive Follicles

Adds passive follicles to the surface as you paint. Passive follicles draw their attributes and behavior from their neighboring active follicles/curves at the start of the simulation. For more information about passive curves, see Passive Fill.

Delete Follicles

Removes follicles from the surface as you paint.

Edit Follicle Attributes

Activates the Follicle attribute list where you can select an attribute, as described in the next section.

Trim Hairs

As you paint over the hairs they are trimmed based on the Value you specify for the Replace operation in the Paint Hair ToolAttribute Editor. The length that is trimmed is relative to the existing hair Length value.

Extend Hairs

As you paint over the hairs, they are lengthened based on the Value you specify in the Paint Scripts Tool, Paint Attributes section, for the Replace or Add operation. The length that is extended is relative to the existing Hair Length value.

Paint Hair Follicles options

These are the options you can select once you have specified a Paint Mode.

Follicle Attribute

Select the follicle attribute to paint using the EditFollicle AttributesPaint Mode. Specifically, you can paint Clump Width Mult, Damp, Start Curve Attract, Attraction Damp, Density Mult, Curl Mult, Clump Twist Offset, Color Blend, Braid, Hair Scale, Inclination, Roll, Polar, Surface Inset, Stiffness.

Tip: If the hair appears to start “off” the surface, you can paint the Surface Inset attribute.

If you paint Curl Mult, but the hair doesn’t become curly or curlier, then the hair system’s Clump Curl value is set to 0.5, which means no curl.

Hair System

Select a hair system to paint, or All hair systems.

Output

If Paint Mode is Create Follicles, then select the type of hair output. For descriptions of hair output types, see Hair Output.

Follicle Density U

If Paint Mode is Creating Follicle, this value represents the number of follicles to create in the U direction.

Follicle Density V

If Paint Mode is Creating Follicle, this value represents the number of follicles to create in the V direction on the surface.

Points Per hair

If Paint Mode is Creating Follicles, this value represents the number of points (segments) each new hair has. As this value increases the hair curve becomes smoother. If the Paint Mode is Trim Hairs or Extend Hairs, this value represents the number of points along the hair affected by the operation.

Hair Length

The length of the hair in world space units (default grid units in the scene views). See Length.

Follicle Override Color

If the Paint Mode is Edit Follicle Attributes, and the Follicle Attribute is Color Blend, you can specify a follicle color override. Control the value of the Color Blend by adjusting the Value in the Tool Settings editor. A value of 1 means the follicle color overrides the hair system color; whereas a value 0 results in the follicle color having no effect on the hair system color. A value between 0 and 1 results in a blending between the Follicle Override Color and the hair system color.
