Cheen
Cheen is especially useful for creating a microscopic look. Cheen differs from the other shaders in
that it has a Gradients channel and Transparency channel. The other material channels are described
later in this chapter.
Gradients page
Color gradient
Is used to alter the base color of the object based on the angle between the camera and the surface
normal (the left side of the gradient is the edge of the object while the right side of the gradient is
the center of the object).
Opacity Gradient
Causes the opacity of the object to change according to the angle between the camera and the surface
normal. White is opaque while black knots are transparent. Knots at the left side of gradient affect the
edge of the object while knots at the right side of the gradient affect the middle of the object.
