Satin material

This is a basic material with anisotropic specular to simulate the look of satin.

Parameters

Lambert Intensity	A multiplier for the diffuse contribution to the material. Since Base Color (in conjunction with the `Cd`) is the diffuse color, this slider can be used to darken and lighten those colors.
Use Base Color	If this box is not checked, the Base Color is ignored. Defaults to on. If Use Base Color and Use Point Color are both off, the surface color will be white.
Base Color	This is the base surface color for the material. Defaults to white.
Use Point Color	If this box is checked, and the point color, `Cd`, is defined, `Cd` multiplied with the Base Color. Defaults to on. If Use Base Color and Use Point Color are both off, the surface color will be white.
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.

Specular Intensity	A multiplier for the specular contribution to the material.
Specular Color	The specular highlight color.
U Roughness	This controls the size or spread of the specular highlight in the U direction.
V Roughness	This controls the size or spread of the specular highlight in the V direction.
