Dot Matrix
Updated: 30 Sep 2025
Add a dot matrix effect to an image.
Dot Matrix
Method #
This node breaks up the image into a matrix of dots, and colours or scales them based on the images colours below.
Custom tiles can be applied to the generated dot matrix - e.g: Using a Gradient.
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.
Resolution
Resolution of the grid, specifically controlling the number of cubes along the y axis.
Tile 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.
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.
