Terrain
This shader generates virtual fractal landscapes featuring mountains and valleys. Using the Type
drop-down list, you can choose the terrain type, from Custom, Mountain, Mars, Moon, Desert and
Polar. Use the gradient to dene the colors of the terrain. The left-most color is the color of the lowest
regions, while the right-most color is the color of the peaks.
Height scales the terrain in the Y direction of the texture axes. For example, with a value of 50, the
fractal would take up half of the object (provided that the texture geometry has been adapted to
the object).
The Terrain shader is not innitely large. Its maximum size is determined by the size of the texture
geometry. If this is smaller than the object on which the shader is used, the shader does not ll the
object. If necessary, t the texture geometry to the object using the Fit To Object command.
The former SLA volume shaders
Long-term users of CINEMA 4D will remember the SLA volume shaders. Over time, these SLA shaders
have become increasingly integrated into CINEMA 4D. Although there are minimal differences
between SLA shaders and standard shaders, SLA shaders still have unique features.
In these pages, the unique parameters of each former SLA volume shader are described rst, followed
by a general description of the shared material channels. You’ll nd these shaders on the Material
manager’s File > Shader menu.
