node. Set the
Glossy
shader's
Roughness
value to
0.350
and its
Color
value to
R 0.529
,
G 0.709
,
B 0.800
.
6. Add a
Layer Weight
node (press
Shift
+
A
and go to
Input
|
Layer
Weight
) and connect its
Fresnel
output to the
Fac
input socket of the
Mix
Shader
node. Set the
Blend
value to
0.500
.
7. Add a
Texture Coordinate
node (press
Shift
+
A
and go to
Input
|
Tex-
ture Coordinate
), a
Mapping
node (press
Shift
+
A
and go to
Vector
|
Mapping
), and an
Image Texture
node (press
Shift
+
A
and go to
Tex-
ture
|
Image Texture
). Connect the
UV
output of the
Texture Coordinate
node to the
Vector
input of the
Mapping
node and the
Vector
output of
the latter to the
Vector
input of the
Image Texture
node.
8. Add a
Bump
node (press
Shift
+
A
and go to
Vector
|
Bump
) and connect
the
Color
output of the
Image Texture
node to the
Height
input socket
of the
Bump
node. Connect the
Normal
output of the
Bump
node to the
Normal
input sockets of both the
Diffuse
and the
Glossy
shader nodes.
Set the
Bump
node's
Strength
value to
0.100
.
9. Click on the
Open
button of the
Image Texture
node, browse to the
tex-
tures
folder, and load the
scales_tile.png
image map. Set
Color
Space
to
Non-Color Data
.
10. Add an
Invert
node (press
Shift
+
A
and go to
Color
|
Invert
) and paste
it between the
Image Texture
node and the
Bump
node. Go to the
Map-
ping
node and set
Scale
for all three axes to
2.000
.
11. Now, box-select the
Texture Coordinate
,
Mapping
,
Image Texture
, and
Invert
nodes and move them to the left to make room for new nodes.
12. Add a
Noise Texture
node (press
Shift
+
A
and go to
Texture
|
Noise
Texture
) and a
Voronoi Texture
node (press
Shift
+
A
and go to
Texture
|
Voronoi Texture
). To their
Vector
input sockets, connect the
Vector
output of the
Mapping
node. Set the
Noise
texture's
Scale
value to
30.000
and the
Voronoi
texture's
Scale
value to
400.000
.
13. Add a
Math
node (press
Shift
+
A
and go to
Convertor
|
Math
) and paste
it between the
Invert
node and the
Bump
node. Rename it as
Add1
and
