Creating a snow material using

procedural textures

In this recipe, we will create a snow material and also fake a slight Sub Surface Scat-
tering effect.

Getting ready

Start Blender and open the 1301OS_03_start.blend file.

How to do it...

Now we are going to create the material:

1. Select the cube and click on New in the Material window, under the Prop-
erties panel, or in the Node Editor window's header. Rename the material
to Snow .
2. Set the Camera view to Rendered .
3. In the Material window on the right, under Surface , switch the Diffuse
shader with a Mix Shader node. In the first Shader slot, select a Diffuse
BSDF shader and in the second slot a Glossy BSDF shader.
4. Set the Roughness value of the Glossy shader to 0.300 .
5. Add a Fresnel node (press Shift + A and go to Input | Fresnel ) and a Math
node (press Shift + A and go to Convertor | Math ). Set the IOR value of
the Fresnel node to 1.300 , and then connect the Fac output to the first
Value socket of the Math node. Set the second Value to 10.000 , the op-
eration mode to Divide , and finally connect its Value output to the Fac in-
put socket of the Mix Shader node.
6. Add a Translucent BSDF node (press Shift + A and go to Shader | Trans-
lucent ) and set its color to R 0.598 , G 0.721 , B 1.000 .
