FFT Deformer

Method

This node deforms a mesh using the waveform of an audio file or a live captured audio input.

Example

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the y-axis.
Rotation Pitch Rotate the object about the x-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

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

Attributes

Name Description
Blend Amount How much the deformer affects the mesh.
Subdivision Order Toggle whether the deformer is added before or after the object is subdivided.
Subdivision Level The subdivision level at which the deformer is applied.
Weightmap Use a weight map to determine where the deformer is more or less effective.
Vertex Source Mode How vertexes are selected to be used by the deformer.
  • Vertex Positions, Vertexes are chosen based on their positions in the scene.
  • Chunks, Vertexes are chosen based on the enclosed section of the mesh they are used.
Deformer Transform Space Select which transform space should be used to calculate the deformations.
  • Local, Deformations are calculated in the Local Space of the object.
  • World, Deformations are calculated in the World Space of the scene.
Update Time Mode How the deformer updates with relation to the time code.
  • Locked To Timecode, The deformer deformations are locked to the time code and the same time will always yield the same deformations.
  • Running / Looping, The deformer deformations are disconnected from the time code and will loop seamlessly at the end of the layer.
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.
Radial The deformation is spread out radially around the Y axis of the deformer.
Displacement Amount How much the deformer displaces the original mesh.
Noise Amount The amount of noise that is applied to the deformer.
Max Displacement Maximum distance the deformer can displace the mesh.
Displacement Direction Change which direction the deformer displaces the objects mesh.
  • Normal, The mesh will be displaced in the direction of the vertex normal’s.
  • Spherical, The mesh will be displaced in a spherical direction from the objects origin.
  • Planar, all vertexes are displaced in the same direction.

Falloff

Name Description
Falloff Enabled Enable falloff from the position of the deformer.
Falloff Shape Select which shape to use to draw falloff from.
  • Sphere, Falloff is drawn outward from a central point, forming a spherical falloff.
  • Cylinder – X/Y/Z, Falloff is drawn outward from a line, forming a cylindrical falloff.
  • Plane – X/Y/Z, Falloff is drawn outward from a plane.
Falloff Range Limits the range the deformer is effective at.
Falloff Inner Range The inner range from which the falloff is calculated from.
Falloff Curve Power How quickly the falloff drops to 0 at the outer falloff.
Invert Falloff Invert the direction of the falloff.
Falloff Curve Visualises the falloff curve, from being completely in effective to not at all.
