Making Might and Magic maps with Trenchbroom

Making maps for Might and Magic is a little bit tricky since it requires usage of some 3D software like Blender or 3Ds Max. To make it easier map editor can be used. MMEditor which is used to edit Might and Magic maps can import 3D models in OBJ format, that means that any program that can export such models can be used for making objects or even entire maps for the game.

Trenchbroom is a map editor for Quake-based games. It will be used to make a map in this guide.

Setting up the editor

Exporting textures from the game

To extract the textures MMArchive can be used. The textures are stored in the /data/bitmaps.lod archive.

PAL or palette files are not required and can be deleted after extraction.

Project structure

Now for Trenchbroom to find the textures a specific folder structure needs to be created

It needs to look like that:

- Project name
  - Bitmaps
    - Any folder name
      ... (textures) ...
    - Any folder name
      ... (textures) ...
    - Any folder name
      ... (textures) ...

Trenchbroom uses texture collections / packs / groups to manage sets of textures, that is why there is a need to create and additional folder in the Bitmaps directory. Structure like that allows to enable or disable folders on the maps when needed.

As an example the following structure will be used:

- Might and Magic Trenchbroom
  - Bitmaps
    - MM6
      ...(textures)...

Now the textures can be placed in the MM6 directory to be further visible by the editor.

However, by default it seems that BMP image support is not enabled. That can be solved by creating custom configuration file for a game that needs it.

Trenchbroom configuration

THERE BE THE CONFIGURATION FILES FOR TRENCHBROOM

To add this configuration: extract the ZIP file into Trenchbroom/Games directory.

If the configuration files worked then a new entry will be visible when creating a new map:

Now Trenchbroom needs a path to the project directory, with textures, created earlier. To set it, press the Open preferences... button. And set the path for Might and Magic to the Might and Magic Trenchbroom folder.

Now creating new map with Might and Magic preset will be loading the project folder and the textures will be available. To proceed start a new map using Might and Magic preset.

The textures will be available once texture collection is selected. Open the Face tab and in the Texture Collections section double click on the bitmaps\MM6 collection. Once the texture collection is loaded the textures should be visible in the Texture Browser.

From now on the process is very similar to making a custom map for Quake, so the general tutorials for Trenchbroom apply.

Limitations

Might and Magic engine has it's own limitations that are not present in Quake engine.

• The textures can not be rotated
• The textures can not be flipped
• The textures can not be scaled

None of that will be applied after the model is exported and will lead to inconsistent results between the editor and the game.
