Attributes
Name |
Description |
---|
Active |
Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. |
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.

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 |
Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. |

Notes
!The processed texture above has been altered from default to show the kind of effect you can get with this node. By default, no change will be made to the node until you input a source.
