Example: Dye color

 

Applies a color tint to the hair. For a dyed hair look, set the melanin to 0, otherwise the melanin will darken the dye color and pheomelanin will introduce redness to it. White means no hair dye. In the example below, the Dye color is set to pink (H=0,S=250,V=104) and we the hue value is adjusted. Melanin is set to 0.4.

Example: Softness

 

Controls the overall softness of the hair by how much the highlights are wrapped around the individual hair strands. Higher values make the highlights wrap almost completely around the strands giving the hair a smoother look, while lower values make the it look crisper. In the example below, the effect is also shown on a single hair strand. Melanin is set to 0.4.

Glint

...

The Glint rollout allows for finer, more focused control of the hair colored highlights that come across and along the strand.

Glint Strength – Controls the strength of the colored highlights across and along the strand.

Glint Variation – Adds a random glint variation along the strand. It affects the glint strength and orientation; the original secondary highlight strength and orientation; the softness, glossiness and highlight shift.

Glitter Strength – Controls the glitter strength. Glitter is additional more focused colorless highlight, which is randomly scattered along the strand. It is more pronounced with hard lightning produced by small or collimated light sources.

Glitter Size – This parameter controls the size of the randomization pattern applied. Increasing the value increases the size of the pattern.

Scale – Internally, the variation along the strand is set in real world units. This parameter allows correction of the appearance of hair not modeled in real world scale. Values below 1.0 shrink the variation pattern, while values above 1.0 elongate it.


Randomization Rollout

...

The Randomization parameters can be used to introduce variation of the general parameter values. When using randomization, different hair strands will receive slightly different values for the below parameteres, so in fact the randomization works on a per strand basis.
