Flood Fill
Flood Fill
Use Flood Fill to identify connected regions and output per-island metadata. It is useful for region-based masking and procedural selection workflows.
Availability
This node requires Pro.
Common uses
- Use analysis outputs as masks or support maps in blend chains.
- Pair with levels or threshold nodes to isolate useful map ranges.
Input ports
-
input -
Usually expects a structured grayscale or height-like input.
Output ports
-
bbox -
info -
Outputs one or more analysis maps depending on node type.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Wrap Edges | bool | true | - |
Behavior
- These nodes compute derived data from shape and height information.
- Outputs are often best consumed by downstream utility and mixing nodes.
Common mistakes
- Analysis nodes can be sensitive to noisy or low-contrast inputs.
- Map interpretation changes with downstream color-space assumptions.
