Altering MTL file to work with MMEditor

For now Trenchbroom exports .MTL files without texture entries. Without them MMEditor will not be able to find the textures required by a model.

Ways to fix that:

Manual

Open .MTL file and you will see a lot of lines similar to this:

newmtl MM6/CsBr128

Note the name after slash, that is a texture name. A texture entry looks like that:

map_Kd CsBr128

map_Kd is an attribute and doesn't change, CsBr128 is a texture name. Line like that needs to be added after each newmtl entry. So the final material definition would look like:

newmtl MM6/CsBr128
map_Kd CsBr128

Bash script

mtlc.sh

Automates the process described above.

If a map compiled by the editor crashes the solution is here.

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.
