Materials Summary

• Materials are the way to give color to an object, including lamps, meshes, nurbs and spline surfaces, and the whole world.
• Materials are accessed through the Buttons Window, Shading (f5) context, Material Buttons sub-context
• The actual color of an object rendered in a scene depends on the color of the lamp, the world, the object itself, and many other factors
• A color is computed based on many settings made in the Materials buttons panels (about 8 of them)
• A mesh can have many materials, each material assigned to a set of faces.
• Material settings can be shared by many objects in the scene
• A Shader is an algorithm that computes the shades of a color to simulate different kinds of coatings and real-world components.
• Diffuse is the name of the base or flat color
• Specular is the name of the highlight color shown under intense light
• Hardness controls the size of the Specular shine
• A Diffuse or Specular color can be a single color or a Color Ramp of varying color values
• SSS is short for Sub-surface Scattering, and adds color based on the color of the interior of the object
• Ambient is the amount of influence that the world color has on the object
• Emit controls the amount of reflected light that the object radiates into the scene (see Radiosity).
• Material Node trees, called Noodles, can be used to give precise and augmented/extended control
• Transparency is set by using either Z-Transparency or Ray-traced Transparency and controlled by the Alpha slider
• Textures add additional layers to the material (see Textures).
