7. Select the Mix Shader node and press Shift + D to duplicate it. Set
the Fac value of this duplicate to 0.300 and then connect the first Mix
Shader node output to its first input socket, and set the Translucent out-
put to the second input socket. Connect the output of the second Mix
Shader node to the Surface input of the Material Output node.
8. Add a Noise Texture node (press Shift + A and go to Texture | Noise
Texture ) and press Shift + D to duplicate it.
9. Add a Texture Coordinate node (press Shift + A and go to Input | Tex-
ture Coordinate ) and a Mapping node (press Shift + A and go to Vector
| Mapping ). Connect the Object output of the Texture Coordinate node
to the Vector input of the Mapping node, then its Vector output to both
the Vector input sockets of the Noise Texture nodes.
10. Add a Math node (press Shift + A and go to Convertor | Math ). Press
Shift + D to duplicate it thrice (so, now you have obtained a total of four
Math nodes). Connect the first Noise Texture node's Fac output (the
gray one) to the first Value input of the first Math node and set the second
Value to 2.000 . Also, set the operator to Multiply .
11. Connect the second Noise Texture node's Fac output to the first Value
input of the second Math node and let its second Value be set to the de-
fault of 0.500 . Again set the operator to Multiply .
12. Now connect the outputs of the two Math nodes to the input Value sock-
ets of the third Math node. Let the operator be set to Add .
13. Connect the output of the third Math node to the first Value input of the
fourth Math node, set its operator to Multiply , and let the second Value
to the default value of 0.500 .
14. Connect the fourth Math node output to the Displacement input socket
of the Material Output node.
15. Now go to the second Noise Texture node and change the Scale value
to 15.000 . Let the other values, also for the first texture node, un-
changed (that is, set Scale to 5.000 , Detail to 2.000 , and Distortion to
0.000 ).
16. Optionally, in the Mapping node set the Scale value to 0.500 for all the
three axes, as shown here:
