See your world's water

This is a made-up sample island. Load a flow map from Straumr to see a world of yours.

1. In game, open the console (F5), type devcommands, then straumr map.
2. Find BepInEx/config/Straumr-flowmap.json in your mod profile.
3. Drop it on this page, or choose it here.

Dedicated server: set [Diagnostics] WorldGenCommand = flowmap in wackah.straumr.cfg; the file lands in the server's BepInEx/config. The file stays in this browser and is never uploaded.

The map shows the world's shape and rivers (Riverheim's or Valheim's) and Straumr's water physics. Rivers and Lakes' streams aren't drawn.

Seed generator: in Valheim (the main menu is fine), open the console (F5), type devcommands, then straumr atlas. It opens this page from your own game and builds any seed with your mods' settings.

Generate a world

Type a seed in the bar above and press Generate. Your game builds it with its own mods and settings, usually in 20 to 90 seconds, then shows the whole world.

Or press This world to map the world you're in, without generating anything.

Zoom in and the game fills in 2 m ground and 4 m currents, square by square.

Water looks wrong somewhere? Press D for the debug view (which river owns each 4 m cell, its head, bank and line) and click a cell for its numbers.

Shows the world's shape and rivers (Riverheim's or Valheim's) and Straumr's water physics. Rivers and Lakes' streams aren't shown: its generator makes them for a real world.

Until then this is a made-up sample island. You can also open a saved flow map: choose a file.
