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

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. |
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. |
Affect Channels
Select which of the RGBA colour channels are affected by the effect.
Inputs
Name | Description | Typical Node Input |
---|---|---|
Source Field | Input a field root node to affect the image. | Field Root |
Collision Image | Adds further locations for the ripples to collide with. | 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 |
