mib_passthrough_bump_map

Category: mental ray > Texture

Shader Family: Texture

Output: Color

This shader is identical to the mib_bump_map shader, including the parameters, except that it returns a color instead of a vector. This color is not modified. This allows the shader to be used in material shader lists by prepending it to the actual material shader. In this configuration, it is called first and modifies the normal vector in the state before the material shader uses it to compute illumination. At the same time, it does not affect the computed result color.

See mib_bump_map for a description of the parameters.
