-This is the tileset file. It contains all the data about the tilesets of the map. Let’s say the map is divided into squares called “tiles”. Each tile has 4 corners. In 3D, we define surfaces using points and in this case tiles are defined by their corners. I call one tile corner a “tilepoint”. So if you want a 256x256 map, you’ll have 257x257 tilepoints. That’s also why a tile texture is defined by each of its four tilepoints. A tile can be half dirt, one quarter grass and one quarter rock for example. The first tilepoint defined in the file stands for the lower left corner of the map when looking from the top, then it goes row by row. Tilesets are the group of textures used for the ground.

-This is the main tileset for the map. Each tileset has an .mpq in the game mpqs which contains some specific textures for this tileset like water or cliff textures. It can be one of the following:

-* B Barrens<br />
-* C Felwood<br />
-* D Dungeon<br />
-* F Lordaeron Fall<br />
-* G Underground<br />

-Indicates how many ground textures there are. There is no maximum except that a tilepoint only allocates 4 bits and thus can save only 16 different values and so only the first 16 tilesets are usable.

-A list of strings of size 4. Example: “Ldrt” stands for “Lordaeron Summer Dirt”<br />

-Indicates how many cliff textures there are. There is no maximum except that a tilepoint only allocates 4 bits and thus can save only 16 different values and so only the first 16 cliffs are usable.
-Note that while the tilepoints allocate 4 bits for which cliff_tilesets_ids to use, the value 15 is reserved for an unknown. This means that while y
