Recreate a map from its seed

Release documentation checked October 2, 2026. Source-based steps, not our own playtest; use the actual build and active mods for your save.

Copy the seed and the complete generation setup

For a generated TF3 free game, choose New Game, select the climate, then open Settings → World → Seed. The release manual says the same seed with the same settings produces the same map. Record the whole setup; a seed copied from a creator's description alone is not enough to verify a match.

What to do

  1. Ask for the exact TF3 seed and a screenshot of the original map setup. Preserve capitalization and characters. If the source is a TF1 or TF2 video, it is not a verified TF3 seed recipe.
  2. Select the same climate in New Game. In Settings, match Map Size, Map Format and Seed, then the terrain sliders and options. Compare the town and industry settings too when matching the complete starting world.
  3. Record the game build and active terrain-generator mods. These are troubleshooting context, not proof that a version difference caused the mismatch. Keep the creator's preview or release version distinct from your own.
  4. Generate the map and compare coastlines, rivers and mountain shapes before investing in construction. Town naming or an appealing screenshot alone does not establish identical terrain.
  5. If it differs, compare the two setup screenshots field by field. A recent TF3 player still could not match creator seeds after copying the text and checking the climate. A reply suggested a preview/release change, but that cause was not confirmed.

How to tell it worked

The generated terrain matches the original reference and the recorded settings allow another player to repeat the setup. Save the map or starting game once it matches so you retain the actual result as well as its seed.

If you are still stuck

Missing setup: request the original settings or a shared starting map. An already-created save with an unknown seed is a separate recovery problem; this guide does not establish a TF3 log-extraction method. Do not use the old Steam app 446800 path as a TF3 instruction.
