Shader Properties
The gradient determines the color of the clouds.
U Frequency [0..+∞]
V Frequency [0..+∞]
Level [0..100%]
U Frequency and V Frequency determine the fineness and shape of the structure. Thus U=1 and V=2 results in rather regular cloud structures, U=1 and V=0.25 gives rather rectangular clouds and the higher the value, the finer (less wispy) the clouds appear.
The Compatibility Mode option ensures that scenes loaded from older versions of Cinema 4D using this shader look the same.
