Dot Matrix

Updated: 24 Feb 2025

Add a dot matrix effect to an image.

Method #

This node breaks up the image into a matrix of dots, and colours or scales them based on the images colours below.

Attributes

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.
Resolution	Resolution of the grid, specifically controlling the number of cubes along the y axis.
Image	Select an image be tiled across the image.
Mode	Change how the dots are placed on the image. Flat : All dots are coloured white. More useful with the multiply blend mode. Colour : Each dot is recoloured based on the colour beneath it. Scale : Each dot is scaled based on the luminance of the colour beneath it. Colour And Scale : Each dot is coloured and scaled based on the colour beneath it.

Affect Channels

Toggle which of the RGBA channels are affected by the effect.

Tile Sheet

These properties control how a sprite sheet can be used for each tile, and how each tile will be picked for the dot matrix.

Parameter	Details
Use Tile Sheet	Enable use of an input tile sheet.
Num Tiles X	Number of tiles along the x axis.
Num Tiles Y	Number of tiles along the y axis.
Tile Layout	How the tiles are sourced for use in the tile matrix. Random : Each tile is sourced randomly for the dot matrix. By Colour : Each tile is sourced using luminance of the tile closest to the original images colour at the dot point. Like Sheet : Each tile is arranged in a sequence matching that of the tilesheet.
