Material Integrators

Illumination

Allows you to use materials for texture production in other materials.

Outputs

• Color - A combined result of direct and indirect lighting
• Direct - Only the direct lighting on the shading model
• Indirect - Only indirect lighting, such as bounced radiosity light, on the shading model

Using a Lambert BRDF piped through the Illumination node into a gradient can create a simple, customizable cel shading method

Slightly more complex, but very satisfying. Create surfaces where the yellow texture you see moves around the sphere as the light plays over it
