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


This node simulates water movements across an image based on an input field using a spring-based water solver.
These properties control the core behaviours of the node.
| Parameter | Details | 
|---|---|
| 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.
| Name | Description | Typical Input | 
|---|---|---|
| Source Field | Input a field root node to affect the image. | Field Root | 
| Collision Image | 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. | 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 |
