Now that we have set the basic shader for the alien skin, let's set an important
component of the material, that is, the bump, by following these steps:
16. Add a Texture Coordinate node (press
Shift
+
A
and navigate to Input | Texture
Coordinate) and two Mapping nodes (press
Shift
+
A
and navigate to Vector |
Mapping); connect the UV output of the Texture Coordinate node to the Vector input
socket of both the Mapping nodes, labeled as
Mapping1
and
Mapping2
respectively.
17. Set the Rotation value of Y of the Mapping1 node to
60°
; set the Rotation
value of Y of the Mapping2 node to
20°
.
18. Add two Voronoi Texture nodes (press
Shift
+
A
and navigate to Texture | Voronoi
Texture) and label them as
Voronoi Texture1
and
Voronoi Texture2
. Connect
the Mapping1 node output to both 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
.
19. Add two Wave Texture nodes (press
Shift
+
A
and navigate to Texture | Wave
Texture) and label them as
Wave Texture1
and
Wave Texture2
. Connect the
Mapping1 node output to the Vector input socket of the Wave Texture1 node.
Set the texture Scale value to
20.000
, Distortion to
10.000
, Detail to
16.000
,
and Detail Scale to
0.300
.
20. Connect the Mapping2 node output to the Wave Texture2 node's Vector input socket,
and set all the texture values exactly as in the previously described one.
21. Add a Noise Texture node (press
Shift
+
A
and navigate to Texture | Noise
Texture) and label it as
Noise Texture1
. Connect the Mapping2 node output
to its Vector input socket, and set the texture Scale value to
120.000
and the
Detail value to
7.000
.
22. Add a ColorRamp node (press
Shift
+
A
and navigate to Converter | ColorRamp),
label it as
ColorRamp1
, and connect the Voronoi Texture1 node's Color output to
its Fac input socket. Set Interpolation to Ease and move the white color stop to the
0.126
position.
23. Add a Math node (press
Shift
+
A
and navigate to Converter | Math), change
Operation to Multiply, and label it as
Multiply1
. Connect the Color output of
the ColorRamp1 node to the first Value input socket of the Multiply1 node, and
set the second Value to
0.050
.
24. Add a MixRGB node (press
Shift
+
A
and navigate to Color | MixRGB) and connect
the Color output of the Voronoi Texture2 node to the Color1 input socket, and the
Color output of the Wave Texture1 node to the Color2 input socket. Set Blend Type
to Difference and the Fac value to
1.000
, and then label it as
Difference1
.
25. Add a second MixRGB node (press
Shift
+
A
and navigate to Color | MixRGB)
and connect the Color output of the Voronoi Texture2 node to the Color1 input
socket, and the Color output of the Wave Texture2 node to the Color2 input socket.
Again, set the Blend Type to Difference and the Fac value to
1.000
and label it as
Difference2
.
