Method #

This node applies a transform to clones based on the analysis of an audio source. The waveform is processed using a set of parameters, allowing for greater control over how the sound is applied to the clones.

Connect the output to the effector input of any cloner node to apply it to the camera system. Multiple effectors connected to the same output will stack, and order of operations chosen by position on the nodegraph.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Blend AmountControls the amount the resulting transforms of each clone after the effector is applied is blended with the original transform.
SpaceThe transform space the Effector uses to influence the clones.
  • Effector - World : Use the world space transforms of the effector to influence the clones.
  • Cloner : Use the transforms in local space to the cloner to influence the clones.
SoundSound used to drive the effector. Can be overwritten by adding a relevant node to the Sound input.
ChannelWhich audio channel is used.
Frequency BandSets the Band EQ to one of the given presets.
Band EQSelects and weights the frequency bands to be used from the sound file.
Time OffsetOffset the time the clones are modified from the time the waveform is at.
Change ThresholdChanges the threshold for what counts toward the effect.
AttackControls the initial time between the current values to the peak.
DecayControls the time between the peak to the sustain level.
Min ValueActs as a minimum threshold for extracting a range of values from the waveform.
Max ValueActs as a maximum threshold for extracting a range of values from the waveform.
Max ClampA maximum value which values will be clamped if they go above.
SpikinessAccentuates peaks in the waveform so they are sharper.
ScaleHow much the output values are scaled.
SmoothnessHow much smoothing is applied between differing values.
FFT Sample ScaleScale the size of the waveform as it is applied.
WaveformVisualises the waveform of of the sound.
DirectionChange how the sound 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.

These properties control where an effector can affect the clones.

ParameterDetails
Falloff ModeChange how the falloff from the original object is calculated.
  • Infinite : There is no falloff, all objects will be affected equally.
  • Linear : Falloff is based on distance from an infinite plane along a chose axis.
  • Sphere : Falloff is based on distance from the plain effectors origin.
  • Procedural : Uses a connected procedural system to describe the falloff area. A procedural node must be input for this property to function.
  • Box : Falloff is based on the distance around a box based at the effectors origin.
Linear Falloff AxisThe falloff axis to use when the effector is in linear mode.
  • +X : The positive x axis.
  • -X : The negative x axis.
  • +Y : The positive y axis
  • -Y : The negative y axis.
  • +Z : The positive z axis.
  • -Z : The negative z axis.
FalloffThe outer radius of the falloff, where the effector no longer effects the clones.
Inner FalloffThe inner radius of the falloff, where the effector effects the clones strongest.
Falloff PowerChange how quickly the nodes falloff from the effector
Falloff SizeThe X size of the falloff when in box mode.
Invert FalloffInvert the direction of the falloff.

These properties control how an effector transforms the clones.

ParameterDetails
Position XOffset the clones x position from the current position.
Position YOffset the clones y position from the current position.
Position ZOffset the clones z position from the current position.
Rotation HeadingOffset the clones y rotation from the current rotation.
Rotation PitchOffset the clones z rotation from the current rotation.
Rotation BankOffset the clones x rotation from the current rotation.
Scale XOffset the clones x scale from the current scale.
Scale YOffset the clones y scale from the current scale.
Scale ZOffset the clones z scale from the current scale.
Uniform ScaleUniformally scale the clones by the same value along all axes.
Position Apply ModeThe method by which the effectors position properties are applied to the clone.
  • Add : The effector position is weighted by the falloff and added to the clone position.
  • Multiply : The effector position is weighted by the falloff and mutliplied to the clones rotation.
  • Replace : The effector position is weighted by the falloff and replaces the clones rotation.
Rotation Apply ModeThe method by which the effectors rotation properties are applied to the clone.
  • Add : The effector rotation is weighted by the falloff and added to the clone rotation.
  • Multiply : The effector rotation is weighted by the falloff and mutliplied to the clones rotation.
  • Replace : The effector rotation is weighted by the falloff and replaces the clones rotation.
Scale Apply ModeThe method by which the effectors scale properties are applied to the clone.
  • Add : The effector scale is weighted by the falloff and added to the clone scale.
  • Multiply : The effector scale is weighted by the falloff and mutliplied to the clones rotation.
  • Replace : The effector scale is weighted by the falloff and replaces the clones rotation.
