Width from Color Contour Shader

The Width from Color shader bases the thickness of contours on the brightness of the color of your materials. The brighter the color, the thinner the contour.

• mental ray material > Advanced Shaders rollout > Click Contour button. > Choose Width from Color (contour).
• Other material > mental Ray Connection rollout > Advanced Shaders group > Unlock Contour if necessary. > Click Contour button. > Choose Width from Color (contour).

Attention: The color used by the shader is not the diffuse color of the material, but instead the rendered color, so lighting has an influence here.

Although the name of the shader uses the word "Color," it would be probably more appropriate to call this shader "Width from Brightness," because only the brightness of a color is taken in consideration.

Interface

Color

Min Width (%)

The relative thickness of the thinnest contour lines, where rendered material colors are brightest.

Max Width (%)

The relative thickness of the thickest contour lines, where rendered material colors are darkest.
