3. Set the Glass BSDF shader's color totally white and the IOR value to
1.309
. Set the
Transparent BSDF shader's color values to
0.448
for R,
0.813
for G, and
1.000
for B.
4. Add a Fresnel node (press
Shift
+
A
and navigate to Input | Fresnel) and connect it
to the Fac input socket of the Mix Shader node. Then set the IOR
value to
1.309
.
5. Add a Glossy BSDF shader (press
Shift
+
A
and navigate to Shader | Glossy
BSDF). Set the color to pure white and the Roughness value to
0.050
.
6. Select the Mix Shader node and press
Shift
+
D
to duplicate it. Connect the
output of the first
Mix Shader
node to the first
Shader
input socket of the
duplicated one, and the Glossy BSDF shader output to the second Shader
input socket. Add a Layer Weight node (press
Shift
+
A
and navigate to
Input | Layer Weight) and connect the Facing output to the Fac socket
of the second Mix Shader node.
7. Add a Voronoi Texture node (press
Shift
+
A
and navigate to Texture |
Voronoi Texture). Set Coloring to Cells and the Scale value to
25.000
.
8. Add a Noise Texture node (press
Shift
+
A
and navigate to Texture | Noise
Texture) and set only the Scale value to
25.000
.
9. Add a Math node (press
Shift
+
A
and navigate to Converter | Math) and set
Operation to Maximum. Connect the Fac output of the Voronoi Texture and
Noise Texture nodes to the first and the second Value input of the Math node.
10. Add a Bump node (press
Shift
+
A
and navigate to Vector | Bump). Connect
the Maximum-Math node output to the Height input of the Bump node, and
its Normal output to the Normal input sockets of the Glass BSDF and Glossy
BSDF shaders.
11. Set the Strength value of the Bump node to
0.250
.
12. Add an RGB Curves node (press
Shift
+
A
and navigate to Color | RGB Curves)
and paste it between the Maximum-Math and the Bump nodes. Set the point in
the little window of the node interface at these coordinates:
0.25455
for X and
0.28125
for Y. Click on the little window to create a new point and set its
coordinates to
0.74091
for X and
0.26250
for Y.
