Basic Coord. Effector Parameter Deformer Falloff


Strength [-∞..+∞%]

Use this setting to adjust the overall strength of the effect. Values of less than 0% and greater than 100% can be entered.


At left a Step Effector without a selection, at right with a selection.

A MoGraph Selection or MoGraph Weightmap tag can be dragged into this field or placed automatically by selecting a Cloner Object and an existing MoGraph selection/weighting, and creating an Effector.

The Effector will then work as follows, depending on the tag’s settings:

As is the case with all Effectors, this slider is used to define the overall strength of the Effector. Values less than 0% and greater than 100% can also be defined.


Maximum [-∞..+∞%]

Use these settings to increase or decrease internal range values.

Minimum [-∞..+∞%]

Use these sliders to limit or expand the internal range of values defined for the transformations.


S.Y is set to 30. If Minimum and Maximum have been set to 0% and 100%, respectively, the clones will be scaled to 0 during times of absolute silence and to 30 when the frequency is loudest. If Minimum and Maximum are set to 50% and 80%, respectively, the clones will consequently be scaled between 15 (silent) and 26 (loud). Values less than 0% and greater than 100% can also be defined.

Sound File

Load a .wav or .aif sound file into this field. The files must be uncompressed.

The following is supported:

One second of Cinema 4D animation is equal to one second of sound from the sound file. In other words, if a Cinema 4D animation is played at 25 fps, the sound file’s frequency spectrum will also be interpolated (sampled) at 25 fps (see also texture path pages).

Start Offset

Enter the frame at which the sound file should start playing here. If 100 is entered, the sound file will start to play at frame 100 and the Sound Effector will have no effect before frame 100. A negative value can also be defined.

Apply Mode

Left: Step mode. Right: All; at the bottom left the clones are not affected by the Effector, the Sound Effector scales the clones only in the Y-direction.

Apply Mode defines how the sound file should affect the clones. There are two options from which to choose:


Each clone will fidget just like the other to the rhythm of the music. No differentiation is made between frequencies


Frequencies will be assigned accordingly to clones, from clone 0 to the end clone. If, for example, the Linear clone method was selected (as in the image above), the lower frequencies will affect the clones at the left and the higher frequencies will affect the clones at the right. Higher frequencies will thus have an effect upon the numbering of the clones. The Effector will affect the clones according to how high or low the volume is set.

Falloff [0..100%]

This setting is only available if Apply Mode has been set to All. Use the Falloff setting to adjust how quickly the Effector value will fall after peaking. A setting of 0% will cause the Effector value to fall instantaneously; increasing the Falloff setting will slow the fall of the Effector value accordingly.

Each time the bass drum sounds the oscillation will abate, until the next beat. Falloff determines the speed with which the oscillation should abate. A value of 0% will cause the oscillation to abate immediately. Increase the value to make the oscillation abate at a slower rate.

Sample Mode

In order for the Sound Effector to be able to ascertain workable values from the chaos of a sound file, a small excerpt (e.g., one millisecond) is analyzed each time it is sampled. From this excerpt, frequency values are ascertained. How this happens is defined by the following modes:


The peak within the excerpt is used.


The average value within the excerpt is used.


This mode offers only two states: 0 and maximum. If no tone is detected, 0 will be output; if even the faintest tone is detected, the Effector will have a maximum effect.

The difference in resulting amplitude between Averageand Peak are minimal. Average results in somewhat smaller amplitudes than Peak.

Clamp Output

At top: Lower Cutoff deactivated; at bottom: active.

This setting is only available if Sample Mode is set to Peak or Average.

Activating this setting will cut the amplitudes off at a specified length. Even if a given sound file has a very high volume at certain spots the Effector will only have an effect at those spots with the maximum value. Extremely high values that can result from large compressions will thus be absorbed.

Lower Cutoff [0..100%]

The effect of a 440Hz sound file. The amplitudes can be cleaned up by setting Lower Cutoff to its maximum value.

Use this setting to remove some of the chaos from the effects of the Sound Effector. Sounds are made up of a mixture of diverse frequencies that are difficult to single out. Lower Cutoff makes sure that frequencies with a lower volume are increasingly ignored the higher this value is set.

Compression [0..100%]

Use this setting to increase the effects with quieter sounds.

Frequency Graph

This function graph offers you a visual representation of the frequency dispersion of the sound sample in its momentary state. The lower frequencies are depicted at the left and the higher frequencies at the right at their corresponding volume settings (decibels). Furthermore, the frequency band is displayed in blue below. The graph will not be updated as the animation is played. Simply click on the graph to get a view the current frequencies.

Filter Shape

Use this function graph to set a varying multiplier across the entire frequency spectrum. A straight line on the Y-level will influence the Effector’s effect, whereas areas near 0 will reduce the Effector’s effect to 0.

Frequency Color

Cube clone using Linear mode and colored according to their frequency using Frequency Color. Additionally, the Sound Effector is set to affect P.Y.

This color gradient will only work if Color Mode is set to Effector Color no Alpha in the Sound Effector’s Parameter tab. The gradient reflects the frequency band: Left the lower frequencies, right the higher frequencies. Note the cubes in the image above that are only slightly affected by the Effector (volume is low in these segments) and have received only little color.

Frequency [0.01..+∞]
Bandwidth [0.01..+∞]

Use these settings to define a frequency band to be used by the Sound Effector. If, for example, Frequency and Bandwidth are set to 2000Hz and 200Hz, respectively, a frequency range between 1800Hz and 2200Hz will be used and the rest marked blue. If the frequency is subsequently changed, the bandwidth will be calculated accordingly so the frequency range can maintain the same number of octaves.

If the bandwidth is too small only a relatively rough Effector resolution can materialize.

Left Channel
Right Channel

Use these settings to define which channels should be used when playing stereo sound files. A mono sound file requires only one channel.

Use Filter

Activate this setting if you want to specify exactly which frequency range should be used by the Sound Effector.

Specific frequency ranges can be filtered out of a sound file. For example, you can select a lower frequency range if you want to filter out higher frequencies.


Press to play the sound file, press again to stop.

Scrub Sound

If this option is active, the sound file will be played while the animation plays or when the time slider is moved manually.
