Category: Texture Generators
Shader Family: Texture
Output: Color
Creates a realistic snow texture, which simulates the effect of snow sticking to objects such as trees or buildings. Based
on a coordinate input, this shader examines the normal of the object's surface and uses this information to decide whether
the snow will stick or not. You can achieve a realistic effect by using this shader in combination with a bumpmap texture
shader. This will cause the snow to follow the bumping of an object.
You can also simulate dust or dirt on an object by applying a noise shader to the snow.

The shader's name. Enter any name you like, or leave the default.
|
|
|
Defines the X, Y, and Z texture coordinates.
|
|
|
Defines the color of the snow. Unless you are simulating a planet or a layer of ash, make this white.
|
|
|
Defines the color of the surface beneath the layer of snow.
|
|
|
Defines the maximum slope at which snow sticks to an object. High for snowdrifts; low for wet, heavy snow
|
|
|
Defines how much the snow thickness decreases with the increasing slope. The higher the value, the sharper the changes between the snow and the surface underneath.
|
|
|
Defines the maximum overall thickness of the snow.
|
|
|
Controls the random variations of the snow's thickness. A value of 0 will probably result in unrealistic-looking snow. Remember
that wind and terrain usually cause snow to fall unevenly, hence this parameter.
|
|
|
Defines the frequency of the snow thickness variation. High for jagged peaks and valleys; low for a smooth layer

Render Tree Usage
Use this shader to drive a parameter with a texture effect anywhere in a render tree. This shader generates a texture that
can be used as a color, a Weight value in a Mixer shader, or to drive any surface shader parameter.
Connect a Texture Space Controller shader to drive the Coordinate value of this shader.
