Voronoi Post Process
Updated: 24 Feb 2025
Add a Voronoi breakup effect to an image.
Voronoi Post Process
Method #
This node generates a Voronoi breakup of the image based on an input particle system, then applies an effect to the image by offsetting the image along a random vector.
Parameters
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.
Affected Channels
Toggle which of the RGBA channels are affected by the effect.
Mode
Changes how the voronoi diagram affects the image.
- Reflection Warping : Use the voronoi triangles to simulate a glass-like reflection of the image.
- Cell Colour : Sample a colour from the image for each triangle.
Warp Amount
Changes how much the voronoi regions are displaced from the image.
Amount
Changes how much the voronoi diagram affects the image.
Noise Distortion
Distorts the output with noise.
Crack Amount
How wide the cracks are between the voronoi regions.
Chromatic Aberration
How much chromatic aberration affects the image.
Inputs
These properties control the core behaviours of the node.
