Egg Shell material

This is a basic diffuse material with a little bump to resemble an eggshell.

A diffuse material with a slight normal perturbation to resemble an eggshell. There are options for color map to be used as the surface color.

Parameters

Surface

Ambient Intensity	A multiplier for the ambient contribution to the material. The ambient lighting model looks only at the ambient lights in the scene. If there are no ambient lights, this slider will have no affect.
Diffuse Intensity	A multiplier for the diffuse contribution to the material. This material uses the Oren-Nayer diffuse calculation. This is a more sophisticated diffuse calculation than Lambert’s.
Diffuse Roughness	This is an exponent for Oren-Nayer diffuse. It controls the size or spread of the diffuse contribution.
Shell Color	This is the main surface color for the material. Defaults to eggshell.
Use Point Color	If this box is checked and the point color, (`Cd`), is defined, then `Cd` is multiplied with the Shell Color. Defaults to on.
Opacity	The opacity color for this material.
Use Point Alpha	If set, the Alpha attributes will be multiplied into the final Opacity. If no Alpha Attribute exists, Opacity is unaffected.
Bump Scale	Controls the overall scale of the noise. With bumping only the normal is perturbed rather than displacing P. This is less expensive than Displacement, and just as effective, with low scale values and/or when surface profile are not visible from the camera.
Noise Frequency	The frequency of the noise pattern. Larger values give a smaller, more frequent patterns.
