In this recipe, we will create a snow material, as shown in the following screenshot, and also fake a slight and cheap Subsurface Scattering effect:
Start Blender and open the 9931OS_Snow_start.blend
file.
In this file, there is a prepared scene with a Spheroid (the usual Cube with a four-level Subdivision Surface modifier), a Suzanne (press Shift + A and navigate to Add | Mesh | Monkey) with a Subdivision Surface modifier as well, and the famous Stanford bunny (http://en.wikipedia.org/wiki/Stanford_bunny), leaning on a subdivided, displaced, and smoothed Plane renamed Snow_ground
. Suzanne is Blender's mascot and an alternative to free test models such as the Stanford bunny itself. By the way, I thought of grouping them in the same scene to have different shapes to test the material.
In the file, there is also a Plane working as mesh-light and a Spot pointing in the opposite...
