Wave

The Wave channel uses real sin curves to affect the hair, this is why some settings are titled Phase and Frequency, for example.

Wave [-∞..+∞%]
Variation [0..+∞%]

Increasing Wave values from left to right.

Use this setting to define the wave strength. Variation randomly affects the strength for each hair individually, within the settings of this channel.

X Scale [0..+∞%]
Y Scale [0..+∞%]

Imagine the hair growing on the Z axis: The X Scale and Y Scale of the sine curve would affect the hair perpendicular to the Z axis in both directions, respectively. Very large values for X Scale and Y Scale generally are not necessary.

Amount [0..100%]

Use this slider to define the percentage of hair that Wave should affect.

Phase X [0..360°]
Phase Y [0..360°]

From left to right, Phase values of 0°, 90° and 180°, respectively.

Phase, which can be set separately for X and Y, defines the initial state of the wave. This is demonstrated in the preceding image.

X Freq [0..+∞]
Y Freq [0..+∞]

These settings define the X and Y frequency of the sin curve, i.e., the number of waves the hair has. In the next image, the two strands of hair in the center were assigned different frequencies.

X Curve
Y Curve

Use these function graphs to define the strength of wave along the entire length of the hair.

Texture

A texture loaded here will use its grayscale values to define the wave of the hair over an entire surface.

Effect on Strands of Hair

Left: Strand without Wave applied. Center: Two strands with Wave applied, but with different frequencies. Right: Strand with a high Wave value.
