Note
Anisotropy is a method for enhancing the image quality of textures on surfaces
that are far away and steeply angled with respect to the point of view; an aniso-
tropic surface will change in appearance as it's rotated about its geometric nor-
mal.
The
Rotation
value of the
Anisotropic
shader set the flow of the highlights on the
mesh, the direction of the specularity rotates as this value increases from 0.000 to
1.000.

Let's try now, starting from the black one, to make a differently processed kind of
bakelite material:
1. Select the
Diffuse
,
Glossy
,
Anisotropic
, and the second
Mix Shader
nodes and press
Ctrl
+
G
to make a group; rename it
Bakelite
.
2. Click and drag the
Diffuse
shader's
Color
socket to expose it; drag also
the
Fac
socket of the
Mix Shader2
node and rename it as
Aniso
. This
will drive the influence of the
Anisotropic
shader on the
Glossy
one.
Click and drag also the
Fac
socket of the
Mix Shader1
and rename it
Spec
: this will drive up the amount of final specularity of the shader. Press
Tab
to close the group.
