Now that we have set the basic shader for the alien skin, let's go ahead with the main
component of the material, that is the bump:
1. Add a
Texture Coordinate
node (press
Shift
+
A
and go to
Input
|
Tex-
ture Coordinate
) and two
Mapping
nodes (press
Shift
+
A
and go to
Vector
|
Mapping
). Connect the
UV
output of the
Texture Coordinate
node to the
Vector
input sockets of both the
Mapping
nodes.
2. Add two
Voronoi Texture
nodes (press
Shift
+
A
and go to
Texture
|
Voronoi Texture,
) rename them as
Voronoi Texture1
and
Voronoi
Texture2
, and connect the first
Mapping
node's output to their
Vector
input sockets. Set the
Scale
value of the
Voronoi Texture1
to
100.000
and the
Scale
value of the
Voronoi Texture2
to
20.000
.
3. Set the
Rotation Y
value of the first
Mapping
node to
60°
.
4. Add two
Wave Texture
nodes (press
Shift
+
A
and go to
Texture
|
Wave
Texture
) and rename them as
Wave Texture1
and
Wave Texture2
.
Connect the first
Mapping
node's output to the
Vector
input socket of the
Wave Texture1
node, set the
Scale
value of the texture to
20.000
,
Dis-
tortion
value to
10.000
,
Detail
to
16.000
, and
Detail Scale
to
0.300
.
5. Connect the second
Mapping
node output to the
Wave Texture2
node's
Vector
input socket and set the values of the texture exactly as the former
one. Set the
Rotation Y
value of the second
Mapping
node to
20°
.
6. Add a
Noise Texture
node (press
Shift
+
A
and go to
Texture
|
Noise
Texture
), rename it as
Noise Texture1
, and connect the second
Map-
ping
node's output to its
Vector
input socket and set the texture's
Scale
value to
120.000
and the
Detail
value to
7.000
.
7. Add a
ColorRamp
node (press
Shift
+
A
and go to
Convertor
|
Color-
Ramp
), rename it as
ColorRamp1
, and connect the
Voronoi Texture1
node's
Color
output to its
Fac
input socket. Set the interpolation to
Ease
and move the white colored marker to the left, very close to the black
colored one (to be more exact, under the end of the last
e
of the word
Ease
).
8. Add a
Math
node (press
Shift
+
A
and go to
Convertor
|
Math
), change
the operation to
Multiply
, and rename it as
Multiply1
. Connect the
Co-
lor
output of the
ColorRamp1
node to the first
Value
input socket of the
Multiply1
node and set the second
Value
to
0.050
.
9. Add a
Mix
node (press
Shift
+
A
and go to
Color
|
Mix
) and connect the
Color
output of the
Voronoi Texture2
to the
Color1
input socket and the
Color
output of the
Wave Texture1
node to the
Color2
input socket. Set
