THE SHADERS • 901
Intensity
Maximum intensity that each object / particle adds.
Ripple
To see the results of this shader, you must render to the Picture viewer.
The Ripple shader is best used in the bump channel. When a particle hits a specied object, the shader
generates a ripple as an animated grayscale. You can use the shader with CINEMA 4D’s standard
particle system or with the Thinking particles module.
Wave Length
The Wave Length denes the distance between the ripple’s crests.
Speed, Amplitude
The Speed parameter denes the speed of the ripples. The Amplitude denes the ripple crest height.
For realistic results, avoid high values.
Falloff
Reality dictates that ripples become smaller the further away they are from their point of origin. Use
the Falloff to simulate this effect.
Minimal Strength
The amplitude (regulated using Falloff) eventually becomes so small that it reaches a value barely
greater than zero. To save rendering time, the Minimal Strength parameter lets you set the moment
at which the entire ripple is removed. Avoid high values or the ripples will disappear prematurely.
