FFT Texture

Method

Generates a texture based on the sound from either a selected or input audio source.

Example
Example Nodegraph

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
Active Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on.
Preview In Viewport Preview the effect blended with alpha in the viewport.
Preview Alpha In Viewport Preview the alpha values in the viewport.
Width The resolution of the effect along its width.
Height The resolution of the effect along its height.
Update Time Mode Change how the effect is generated with respect to the scene’s timecode.
  • Locked To Timecode, The effect is locked to the time code.
  • Running / Loopable, The effect is generated seperated to the timecode.
Static Image (Process Only Once) Only process the image once, making a more efficient scene. Animated Post-FX nodes will not function with this enabled.
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.
Offset Offset all values output by the texture.
Smoothness How much smoothing is applied between differing values.
Falloff Range Range in which the sounds data will be tracked.
Waveform Visualises the waveform of of the sound.

Rendering

Name Description
Colour Add a colour filter over the image.
Blend Amount The amount the generator is blended with the output.
Blend Mode Choose how the image blends with the scene. See Blend Modes for details.

Inputs

Name Description Typical Node Input
Sound Use an input sound to override the sound attribute. Play Sound
Colour Ramp Specifies a range of colours the generator can use. Colour Ramp
Transform Modifier Links all transform properties to the input node. Null
Target Node Always faces the x-axis towards the inputs anchor point. Null
Local Transform Override Override the transformation values of the node, relative to its parent. Null

Outputs

Can be connected to any node which requires an image input.
