Shader Family: Surface Material
This shader calculates Phong illumination, given ambient, diffuse, and specular RGB colors, a specular exponent, and a light list.
| Name |
The name of the shader node displayed in the render tree. Enter any name you like, or leave the default. |
| ambience |
A multiplier for the ambient color. The ambient and diffuse color can be derived from the same subshader result (a texture mapper, for example) and the ambient brightness can be reduced to avoid losing the effect of illumination. |
| ambient |
A constant color offset. |
| diffuse |
Added to the result for each light, after multiplication with the color returned by the light and a weight based on the dot product of the incident ray direction and the light direction. |
| specular |
The color of specular highlights. |
| exponent |
Controls the width of the specular highlight. Smaller values increase the size. |
| mode |
The mode selector for the light list. For more information, see Setting the Light List Mode [Direct Illumination]. |
Creates a light list to specifiy which lights should produce the effect. For more information, see Using Light Lists [Direct Illumination].
