Create a key just below the new one,
and set its Color to
151, 97, 64
, its

100%
, and its Parameter to
0.82
.
cc.
The lowest of this set of three new
keys should have its Alpha at
17%
and
its Parameter at
2.25
.
x.
Create a new key just below that one,
and set its Color to
106, 53, 40
, its
Alpha to
0%
, and its Parameter to
2.66
.

crucial).
Figure 4-64: Each added texture layer adds another
level of detail to your surfaces.
dd. Select
Add Layer | Procedural
,
make sure the Procedural Type is
Tur -
bulence
, and set the Texture Color to
141, 71, 71
.
ee. Change the Layer Opacity to
20%
so
this adds just a
hint
of “irregular” color
to the “clean” metal.
Figure 4-63: Exact placement of these keys isn't
crucial, but do try to get them close. The outer two
will hold the colors we're getting from the gradient
in place, while we use the center one to make a
darker band through one level of the bump's
height.
aa. Set the Alpha of the topmost of those
three new keys to
32%
and its Parame-
ter to
1.75
.
bb. Set the Color of the next lowest key to
0, 0, 0
, its Alpha to
12%
, and its
Parameter to
2
.
