Create a world

Create a world

This creates a flat terrain and its world configuration. You can then replace its heights with generated or edited terrain.

Create a 2560 × 2560 m world

1. Make an empty folder for the map.
2. Open World & Terrain → World Builder.
3. Select the Stock Map Creator tab.
4. Set Map Name to symdemo. Use 1–8 alphanumeric characters.
5. Select a World / Biome, such as Moon.
6. Under MakeTRN Compatibility, enter Width: 2560 and Depth: 2560. These overrides take priority over Map Size.
7. Leave Empty elevation (/e) at 0 for this example. Leave Layer file (/p) empty.
8. Click GENERATE MAP FILES and choose your empty folder.
9. Check the log and confirm that the folder contains symdemo.trn, symdemo.hg2, and symdemo.mat.

Use dimensions that are multiples of 1280 m. Other requested dimensions are normalized to terrain zones; check the actual size reported in the log.

File	Contains
.trn	World dimensions, terrain textures, lighting and other world settings.
.hg2	Terrain heights.
.mat	Terrain texture placement. This is separate from an Ogre .material file.
.lgt	Terrain lighting, when supplied or rebaked. Stock Map Creator does not generate this file.
.bzn	Mission objects and mission data. Stock Map Creator does not generate this file.

Add generated terrain

Follow Generate symmetric terrain, using Zones X: 2 and Zones Z: 2 to match this world.

Export the generated heightmap as symdemo.hg2 into the world folder, replacing the flat file. Keep a copy before replacing an existing map's terrain.

The files must agree on size. For this example, the TRN is 2560 × 2560 m and the HG2 is 2 × 2 zones / 512 × 512 samples.

Replacing the HG2 changes heights only. Follow Check your map to repaint terrain, rebake lighting and test the mission.

A world is not a complete mission

You still need a BZN mission that refers to this terrain, along with the appropriate mission and multiplayer setup. Create or adapt that in the game's map/mission workflow. The Toolbox's terrain generator does not create starting bases, teams or multiplayer spawns.
