Bump Map Warp - Notch Reference Manual

Method

This node warps an image based off of a bump map. The warp is generated by creating a copy of the image with a slight offset and multiplied. If there is no input connected to the Image Node input then the scene render is used as a source bump map.

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.
Displacement Amount	How much the warp effect displaces the image.
Falloff Range	How far the falloff for the warp reaches.
Displacement Amount X	How much the images are displaced along the x axis.
Displacement Amount Y	How much the images are displaced along the y axis.
Bias Displacement Direction (Grey = 0)	Change the displacement direction so that a middle grey value has no displacement, and values darker or brighter will push the displacement in opposite directions.
Normalise Displacement Direction	Force the displacement direction to apply evenly in each direction. This does not include alpha modulation.
Modulate Displacement Amount By Alpha	Control the strength of the displacement based on the input images alpha channel

Channel Mixer

Control how much the RGBA channels displace the X and Y axes individually.

Inputs

Name	Description	Typical Node Input
Image Node	The source bump map for the warp.	Video Loader
Falloff Node	Add a gradient that controls how far the effect affects the image.	Gradient 2D
