THE SHADERS • 923
Volumetric Shaders
Most of CINEMA 4D’s shaders are channel shaders, i.e. shaders that you can load into material channels,
such as Color and Bump. In addition to the channel shaders, CINEMA 4D offers a number of shaders
that are materials in their own right. You cannot load these materials into material channels.
To create a material shader, choose the desired shader from the Material manager’s File > Shader
submenu.
Fog
This shader simulates volumetric fog.
Color
The color of the fog.
Samples
Samples denes the average number of samples that will be computed per raytracing ray. The higher
this number, the greater the quality of the fog, but the longer the calculation time.
Start with low numbers, such as 6 or 8. Increase this value only if you get
disturbing artefacts or if the detail is not high enough. After a certain point
(depending on the scene), higher sample values will not produce better
images.
