FFT Effector

Method

This node applies a rotation, scale and translation to clones based on the analysis of an audio input or file. The waveform is processed using a set of parameters in the same way as the Sound Modifier.

The Effector Transform parameters determine the rotation, scale and translation that will be applied to the clones. The amount the translation, scale and rotation are applied to each clone is weighted depending on the falloff function. The effector’s falloff is generated using the effector node’s transform and the Falloff parameters. The falloff shape is determined by the Falloff Mode parameter, with a radius provided by the Falloff parameter and a box falloff from the Falloff Size parameter.
The way in which the effector’s rotation, scale and translation are applied to the clone is determined by the Position/Rotation/Scale Apply Mode parameters.

Example

Transform

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Blend Amount Controls the amount in which the resulting rotation, scale and translation of each clone after the effector is applied is blended with the clone’s original rotation, scale and translation.
Space The transform space in which the Effector is processed.
  • Effector – World, use the effector’s transforms in world space.
  • Cloner, use the cloner’s transform space.
Sound Sound file used to drive the effect.
Channel Which audio channel is used.
Frequency Band Sets the Band EQ to one of the given presets.
Band EQ Selects and weights the frequency bands to be used from the sound file.
Time Offset Offset the time the clones are modified from the time the waveform is at.
Change Threshold Changes the threshold for what counts toward the effect.
Attack Controls the initial time between the current values to the peak.
Decay Controls the time between the peak to the sustain level.
Min Value Acts as a minimum threshold for extracting a range of values from the waveform.
Max Value Acts as a maximum threshold for extracting a range of values from the waveform.
Max Clamp A maximum value which values will be clamped if they go above.
Spikiness Accentuates peaks in the waveform so they are sharper.
Scale How much the output values are scaled.
Smoothness How much smoothing is applied between differing values.
FFT Sample Scale Scale the size of the waveform as it is applied.
Waveform Visualises the waveform of of the sound.
Direction Control how the FFT is applied to the Cloner system.
  • Linear, The bands are spread along the x axis, and time progresses in the positive z axis.
  • Radial, The bands spread out radially around the z axis, and time progresses in the positive z axis.
  • Spherical, The bands spread out radially around the z axis, and time progresses in the negative z axis. Only position x is used to affect the clones.

Falloff

Name Description
Falloff Mode Change how the falloff from the original object is calculated.
  • Infinite, There is no falloff.
  • Linear, Falloff is propagates along the x axis.
  • Sphere, Falloff is based on distance from the plain effector origin.
  • Procedural, Use a procedural system to describe the falloff area.
  • Box, Falloff is based on a box.
Linear Falloff Axis The axis to use for a linear axis falloff.
Falloff The outer radius of the falloff, where the effector no longer effects the clones.
Inner Falloff The inner radius of the falloff, where the effector effects the clones strongest.
Falloff Power Change how quickly the nodes falloff from the effector
Falloff Size The width, length and height of the falloff.
Invert Falloff Invert the direction of the falloff.

  • Add, the effector scale is weighted by the falloff and added to the clone scale.
  • Multiply, the effector scale, multiplied by the clone scale, is blended with the clone scale by the falloff.
  • Replace, the effector scale is multiplied by the falloff and replaces the clone scale.
