Method

This node displaces the position of a particle based on an image or input video source. This is very similar in operation to the Displacement Map Deformer node for 3D objects.

For this node to operate an image must be supplied either via the Image attribute or connected via the Image Node input. When an Image Plane node is connected to the Image Node input the transform from the image plane will be used, so the sampled pixels in the displacement map deformer correspond with the pixels on the image plane in 3D space.

Example

Attributes

Name Description
Image How much the particle colours adapt to the image colours.
Displacement Mode Determines how the displacement direction is calculated.
  • Directional, displace the particles along the orientation direction of the displacement node.
  • Radial, displace the particles along the direction outwards from the position of the displacement node.
Displacement Colour Mode Changes how the colour of the video input displaces the particles position.
  • Luminance, displacement is based on luminance of the pixels in the image.
  • RGB, displacement is based on RGB, and the colour channels effect the direction components individually: red affects X, green affects Y, blue affects Z.
  • Alpha. displacement is based on the alpha values of the image.
  • RGB Biased, As RGB, but the incoming value is scaled and biased so mid grey is considered 0.
  • Bump XY, displacement is based on the image processed as a bump map.
Blend Mode How the particle shading blends.
Blend Amount Control how much the shader affects the particles.
