Method

This node warps an image based on the movement vectors of an input field. The field movement vectors are used to deform a position lookup grid over time, which is then used to sample the image every frame. This allows animating deformations to be applied to separately animating sources.

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.
Velocity Scale Scales the velocities of the input field.
Displacement Scale Scale the amount the field root effects the image.
Velocity Dampening Dampen the effect of the field root.
Brightness Scales the brightness of the result.
Width Controls the width of the underlying deformation grid. The greater the width of the grid, the more memory intensive the processing is but the sharper the result.
Height Controls the height of the underlying deformation grid. The greater the height of the grid, the more memory intensive the processing is but the sharper the result.

Affect Channels

Select which of the RGBA colour channels are affected by the effect.
