Industry Flows

The industry window shows cargo-flow arrows for one industry at a time. Industry Flows shows them for every industry of the types you pick, all at once, so you can see where to build supply chains without clicking through each industry.

Click the Industry Flows button (a factory icon) in the top-left button ridge to open the panel.

Features

• Search by industry name or by cargo ("fuel" finds the oil refinery). Each type is listed with its input and output cargos and how many are on the map.
• Select one or more types to draw their arrows on the map.
• Toggles: Outputs (to the industries and towns that take their cargo), Inputs (from their suppliers) and Potential links.
• Live arrows: moving arrows carry cargo that was delivered in the last year. Faded, still arrows are possible links with no cargo moving yet.
• Summary: a line counts the industries, links and active links.

Notes

• Arrows show while the panel is open and clear when you close it. Clicking an industry or town opens its window as usual; close it to return to your flows.
• Your search, selection and toggles are kept for the rest of the session.
• Very busy maps are capped at 400 arrows, active ones first.
• Reads the game state only: it changes nothing in the simulation, stores nothing in the savegame, and can be added to or removed from existing saves.

Settings

• Top bar button (default Icon): the button that opens the panel. Icon: a factory icon on a dark tile, like the game's data layers button. Text: the word "Flows".
• Debug: performance log (default Off): writes timing lines to the game's log file every 30 s. Only for tracking down slowdowns.

Changelog

Revision 7 (2026-10-20)

• Fixed for PlayStation 5: the flow map no longer risks crashing the UI where the console's game lacks parts the PC version has (map icons, the map selector, cargo icons). Missing parts are left out instead.

Revision 6 (2026-10-13)

• The top bar button now has the same spacing as the game's data layers button and other mods' buttons, so a row of buttons looks even.

Revision 5 (2026-10-12)

• The game's data layer windows (Infrastructure, Traffic and the others) now open below the top-left button row instead of under its buttons.
• New: mod setting "Top bar button": the button that opens the panel is now a factory icon on a dark tile that stays pressed while it is open, like the game's data layers button (default), or the word "Flows" as before.
• Fixed for PlayStation 5: the Industry Flows window no longer crashes the UI when it opens. A window option the platform doesn't support (such as the close button) is left out instead.

Revision 4 (2026-10-10)

• Fixed: fewer stylesheet rules (17 → 13), so large mod sets no longer hit the game's load crash (the game crashes on load when mods add too many style rules).

Revision 3 (2026-10-10)

• New: translations into Russian, German, French, Spanish, Italian, Dutch, Polish, Portuguese (Brazil), Japanese, Korean and Chinese (Simplified and Traditional). The mod follows the game's language setting.

Revision 2 (2026-10-08)

• Performance: the arrows for many selected industries are worked out about a quarter faster, both on each refresh and when you tick a type or toggle.

Revision 1 (2026-10-07)

• First release.
