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
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.
Simulation Speed Control the speed at which the warp is animated.
Speed The speed of the ripples as the move over the image.
Length The distance between springs. Larger values make the ripples move faster.
Displacement Scale Scale the displacement the water ripples simulate.
Velocity Dampening Controls how much the velocities are dampened over time.
Brightness Controls the brightness of the ripple displacements composited over the image so they can be seen, giving a lighting effect.
Trigger Source Channel Choose what triggers and affects ripples.
Simulation Width The width of the grid used for the simulation, in cells.
Simulation Height The height of the grid used for the simulation, in cells.

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