12. Add a Mix node ( Shift + A | Color | Mix ), set the Blend Type to Differen-
ce and the Fac value to 1.000 ; connect the Color output of the first Wave
Texture to the Color2 input socket of the Difference node and the Color
output of the second Voronoi Texture to its Color1 input socket.
13. Press Shift + D to duplicate the Difference node and connect the Color
output of the second Voronoi Texture node also to its Color2 input sock-
et; connect the Color output of the second Wave Texture to the Color1
input socket of this second Difference node.
14. Press Shift + D to duplicate again a Difference node, change its Blend
Type to Multiply , and connect the output of the first Difference node to
the Color1 input socket and the output of the second Difference node to
the Color2 input socket.
15. Add a Math node ( Shift + A | Convertor | Math ) and connect the output
of the Multiply node to the second Value input socket; connect the Color
output of the first Voronoi Texture node to the first Value input socket.
16. Add two Bump nodes ( Shift + A | Vector | Bump ); connect the first
one to the Normal input socket of both the Diffuse and Glossy shader
nodes, the second to the Normal input of the Anisotropic shader. Set
the Strength of the first Bump node to 0.050 and the Strength of the
second one to 0.025 . Connect the output of the Add node to the Height
input sockets of both the Bump nodes.
17. Add a ColorRamp node ( Shift + A | Convertor | ColorRamp ) and paste
it between the first Difference node and the Multiply node; set the In-
terpolation to B-Spline and move the white color marker 3/4 to the left.
Press Shift + D to duplicate and paste it between the second Difference
node and the Multiply node too.
18. Add a Math node ( Shift + A | Convertor | Math ) and paste it between the
first Voronoi Texture node and the Add node; set the operation to Mul-
tiply and the second value to -0.200 .
19. Press Shift + D to duplicate the Multiply math node and paste it between
the multiply Mix node and the Add node; set its second value to 0.100 .
