Method #

This node simulates water movements across an image based on an input field using a spring-based water solver.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
ActiveEnables 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 AmountChanges 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.
Simulation SpeedControl the speed at which the warp is animated.
SpeedThe speed of the ripples as the move over the image.
LengthThe distance between springs. Larger values make the ripples move faster.
Displacement ScaleScale the displacement the water ripples simulate.
Velocity DampeningControls how much the velocities are dampened over time.
BrightnessControls the brightness of the ripple displacements composited over the image so they can be seen, giving a lighting effect.
Trigger Source ChannelChoose what triggers and affects ripples.
Simulation WidthThe width of the grid used for the simulation, in cells.
Simulation HeightThe height of the grid used for the simulation, in cells.

Toggle which of the RGBA channels are affected by the effect.
