In-Depth Information
The colors and values are fairly subjective and you'll most likely want to tweak them as you work. These
warm colors are meant to give the impression of tissue beneath the skin. At the moment, the gradient
is applied to the entire surface. The Fresnel Factor slider is going to shift the gradient colors toward the
edges when it is set to a positive value and toward the center when it is at a negative value. Many of these
settings will be tweaked once you start putting the material together, but at least now we have a place to
start.
Of course, this is just a gradient—it is not subsurface scattering just yet. To finish the basic effect you
need to adjust some settings in the Mixer.
