Overview
The basic region-system renderer that turns a RegionMap into a visible image. It fills regions with random colors, palette colors, or a solid color. It accompanies region work from checking partitions to preparing flat terrain fills.
Usage tips
The go-to two-stage workflow is
RandomColorwhile working to inspect boundaries, thenPalettefor production colors.Palette mode maps region IDs to palette indices. When ID order matters, arrange it upstream, for example with
id_orderinimage_to_regions.The filled result is an ordinary image, so finish it with normal image nodes such as noise and lighting.

Use: temporary per-region colors, terrain surface fills, and palette assignment checks
Modes
| Value | Description |
|---|---|
RandomColor |
Assign a deterministic random color to every region ID |
RandomGray |
Assign a grayscale value to every region ID |
Palette |
Cycle through the connected Palette in region-ID order |
RegionId |
Visualize region ID as luminance |
Region Fill converts a RegionMap for downstream ordinary image processing. Use it
with Region Border when only boundaries are needed.
This node is the shortest route to checking colors by region. Use
Region Pattern Assign to vary palette assignment per region or apply pattern images.
For checking IDs, Region Debug Preview is a better fit.
