Texture Settings

You may adjust other settings to change the appearance of the head.

Diffuse, Ambient, and Specular Color Settings

These three settings specify how the head reflects the surrounding light. The Diffuse Color specifies the overall color reflected from the head when the light hits it, and the Specular Color represents the color of the brightest spot of the head.

Original Appearance	Diffuse Color: (Adjust the skin color)	Specular Color: (Create the suntan effect)
You have to increase the value of the Specular to see the color effect.

Independent from the Diffuse Color

Self-illumination defines how the actor's head ignores the Diffuse color. The higher the value, the less the Diffuse color affects the head.

Diffuse color: Self-illumination: 15	Diffuse color: Self-illumination: 100
It is very easy to create a cartoon look by using the Self-illumination feature. The Light color is white in this example. The Diffuse color is totally ignored as the value is 100.

Independent from the Light Effect

Self-illumination defines how the actor's head ignore the effect from the light. The higher the value is, the less the light affects the head.

Light color: Self-illumination: 15	Light color: Self-illumination: 100
The Light color is totally ignored as the Self-illumination value is 100. When the light effect is ignored, the shadow effect will decrease as well.

Create Oily or Wet Look Face

If you plan to create an actor with oily or wet look face, you need to adjust two parameters: Specular and Glossiness.

Specular reflection is the mirror-like reflection of light from the head, in which light from a single incoming direction is reflected into a single outgoing direction.
Glossiness is based on the interaction of light with physical characteristics of a surface. Materials with smooth surfaces appear glossy, while very rough surfaces appear mat.

Specular: 10 Glossiness: 10	Specular: 100 Glossiness: 30
