## Water FX

I spent literal days tracing water polygons on maps by hand. Every river, lake, and puddle: click, click, click, adjusting vertices for hours. Across a large map library that prep gets slow. Waterline flood-fills water and overlays animated caustics instead.

Click on water in your map and Waterline traces the shape automatically using flood-fill detection. It then renders a live animated overlay with Voronoi caustics, background distortion, and configurable edge fade.

You can tune everything with sliders that update in real time: speed, intensity, opacity, distortion, scale, and flow direction. Built-in presets (River, Lake, Puddle, Coast, Deep Sea) set sensible defaults, and you can save your own per-world profiles.

Shift+Click adds area. Ctrl+Click subtracts. Ctrl+Z undoes the last change.

Procedural border wall generation now lives in **Ionrift Cartographer**, which is the home for map preparation tools.
