Transport Fever 3 map editor: Step-by-Step Setup Guide

A strong Transport Fever 3 map editor workflow begins by separating confirmed design principles from assumptions. The available reference material describes the Transport Fever 2 editor, where creators can generate terrain, import and export heightmaps, place towns and industries, create an initial street network, and edit downloaded maps. Those features provide a useful planning baseline, but individual Transport Fever 3 tools and interface details should be verified in the released game.

The editor should be treated as a preparation environment rather than a normal company-building session. In the documented workflow, station and depot construction, track construction, vehicle management, and line management are unavailable while editing. Financial costs may appear during editing, but they do not determine the later gameplay economy.

Before sculpting terrain, lock the settings that shape the entire map. The documented editor workflow places map size, format, climate, and seed near the beginning. Climate, map size, and format cannot be changed inside the editor afterward, so changing them later generally means starting another map.

The seed controls procedural randomization. With the same seed and the same settings, terrain generation and asset distribution can be reproduced. This makes seeds valuable for iteration: you can change one design choice while preserving the underlying generated layout.

Terrain design determines whether future transport lines feel purposeful or forced. Begin with broad geographic decisions: where the main valley runs, which areas are separated by mountains, where water creates natural boundaries, and which regions should remain difficult to reach.

The heightmap tool supports three distinct workflows: generating a new map, importing a grayscale heightmap, and exporting elevation data. Generation is useful for procedural drafts. Importing gives creators control over a prepared grayscale image. Exporting creates a PNG representation of the terrain, with an optional 16-bit grayscale format and a possible STL mesh output for high-resolution surface data.

Imported heightmaps require careful calibration. Black and white values are translated into minimum and maximum terrain heights. For example, a map intended to range from sea level to high mountains needs appropriate elevation limits. The water level also needs to match the intended shoreline because the documented Transport Fever 2 workflow uses a flat water level across the map.

Use the terrain tool after the major elevation structure is established. Smooth transitions near towns and industries usually create more practical building areas than placing every important location on steep slopes. Keep the most dramatic terrain for boundaries, scenic routes, or deliberate engineering challenges.

A functional map needs more than isolated points of interest. Towns should have enough separation to create meaningful passenger relationships, while industries should be positioned to support understandable cargo chains. Manual placement gives precise control, and automated generation provides a faster way to distribute locations across a large map.

The documented town and industry generators use sliders and seeds. Existing towns can be preserved when generating additional settlements, which allows a creator to combine a hand-designed core region with procedural expansion. The same principle applies to industries.

Main street connections form another important layer. The connection generator displays towns as points and proposed links as lines. You can add or remove connections in the preview before generating the actual road network. This makes it possible to establish the intended regional structure before normal gameplay begins.

Avoid placing too many towns close together without a clear reason. More towns, roads, and vehicles can increase pathfinding calculations later. Close settlements also create more reachable destinations for inhabitants, which can raise simulation demands as the map develops.

A useful first draft usually contains:

• One primary urban region.
• Several secondary towns with distinct travel relationships.
• Industries placed with visible but not excessive separation.
• Road connections that create regional access without covering every valley.
• Open areas reserved for future stations, depots, or route expansion.

Map editing is only half of the workflow. After the geography and placement are complete, test the map as a normal player would experience it. Check whether the first towns have practical road access, whether industries can be reached without extreme construction, and whether the terrain offers multiple strategic choices.

Use this validation sequence before publishing or distributing a map:

The documented sharing workflow stores a map reference and its encapsulating mod information in a text file named after the map. That file contains an individual key used by the game to locate the correct mod in its staging area. The key is not the same as a Steam Workshop ID, so losing the text file can make later recovery or updating difficult.

Keep a working copy of the map, the source heightmap, the seed, and a short design note. A simple note should record the intended climate, map format, major regions, unusual constraints, and any required assets. This documentation is especially useful when revisiting a project months later.

The following answers use the documented editor workflow as a planning baseline while avoiding unsupported claims about features that have not been confirmed for Transport Fever 3.
