DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage shader library.
Shader Type: Illumination (surface)
Performs the computation of Lambert illumination on the object. Only surface shading is computed -- no reflection, transparency, or refraction is calculated.
This illumination shader can be used almost anywhere in a render tree, just like a surface shader. The illumination nodes are faster and take less memory since they don't calculate any reflections, refractions, or transparencies. You can use any number or combination of illumination and surface shaders to control various parts of your effect. Illumination shaders are often mixed (as the Base Color using a mixer shader) with textures to add realism to them. Also, you can use textures to control color inputs (such as Diffuse or Ambient) or scalar output nodes (such as gradients or fractals) to control refraction or translucency.
