TF3 TF3 SEEDS TRANSPORT FEVER 3

SETUP GUIDE

Experimental map sizes

The regular map menu is not the whole list. On PC, a single flag in settings.lua exposes four additional sizes.

Official caution: enabling the flag can also change the economy in existing saves and may be unstable. This is an official configuration option, not a modification.

The four experimental sizes

Size1:1 edge (km)Availability
Tiny 4.096 Experimental, PC only
Huge 20.480 Experimental, PC only
Megalomaniac 24.576 Experimental, PC only
Gigantomaniac 28.672 Experimental, PC only

The four experimental sizes are Tiny, Huge, Megalomaniac, Gigantomaniac. They do not appear in the normal size list until the flag is turned on.

Turn on the flag

  1. Close Transport Fever 3 completely.
  2. Open the game’s userdata folder from its launcher or installation documentation.
  3. Open settings.lua in a plain-text editor.
  4. Set experimentalMapFeatures = true.
  5. Save the file and restart the game.
experimentalMapFeatures = true

Back up settings.lua before editing. The biggest sizes cost more memory and simulation time.
