Ionrift Waterline - New module dropped!

Ionrift Waterline does two things - animated water overlays and procedural border walls. Both for Foundry VTT v12/v13.

How the water works

I have spent literal days of my life tracing water polygons on top of maps by hand. Every river, every lake, every puddle - click, click, click, adjusting vertices for hours. Across hundreds of maps this becomes genuinely soul-destroying prep work. So the whole point of this module was to make that go away.

Click on water in the map. Waterline traces the shape using flood-fill (same idea as the paint bucket tool) and drops an animated overlay on top - Voronoi caustics, background distortion, edge fade. The effect runs as a PIXI shader directly on the canvas.

Everything is tunable in real time. Speed, intensity, opacity, distortion strength, scale, flow direction. There are built-in presets for rivers, lakes, puddles, coastlines, and deep ocean. You can also save custom profiles per-world.

Shift+click adds more water. Ctrl+click removes it. Ctrl+Z undoes. Its additive, so you can build up complex bodies from multiple clicks.

Install

Free module. Requires Ionrift Library.
