Shaders are composed of nodes just like other Maya objects. Within these nodes, attributes define what shaders do. Here is a brief rundown of the common shader attributes with which you’ll be working:
Color An RGB or HSV value defines what color the shader is when it receives a neutral color light. For more on RGB and HSV, see Chapter 1, “Introduction to Computer Graphics and 3D.”
Transparency The higher the Transparency value, the less opaque and more see-through the object becomes.
Although usually expressed in a black-to-white gradient, with black being opaque or solid and white being totally clear, transparency can have color. In a color transparency, the shader’s color shifts because only some of its RGB values are transparent, ...
