Attributes

Name Description
Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount Changes the opacity of the new effect over the original image.
Blend Mode (RGB) Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha) Change how the generated effect blends with the parent image alpha.
Displacement Amount How much the warp effect displaces the image.
Noise Scale Scale the size of any noise generated.
Lacunarity How large the gaps between the generated noise is.
Gain The smoothness of the generated noise.
Falloff Range Limit the range from which the warp falls off an becomes ineffective.
Animation Rate Control the speed at which the noise is animated.
Update Time Mode How the effect updates with relation to the time code.
  • Locked To Timecode, The effect is locked to the time code and the same time on the time code will always yield the same image output.
  • Running / Looping, The effect is disconnected from the time code and will loop seamlessly at the end of the layer. This also means that animated speed values will change smoothly.

Affect Channels

Select which of the RGBA colour channels are affected by the effect.

Inputs

Name Description Typical Node Input
Falloff Node Add a gradient that controls how far the effect affects the image. Gradient 2D
Mask Image An area which is not affected by the warp effect. Image Plane
Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance. Envelope Modifier
