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.
Falloff Range How length of the blend to the displacement.
Max Displacement Maximum height of the ripple.
Ripple Speed Speed at which the ripple moves.
Ripple Peak Sharpness How sharp the peaks of the ripples are.
Ripple Scale How many ripples are generated.
Ripple Repeat Rate How many seconds between each new ripple.

Affect Channels

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

Name Description Typical Node Input
Falloff Node Add a gradient that controls how far the effect affects the image. Gradient 2D
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
