• Map files – These are not to be confused with map as in the map you use in the game to find your way, but of UV maps. Where the models are represents the 3D objects of the game world, the map files give each of the objects a distinctive look, like the skins of characters and monsters, the colour of armour and armour. There are also special map file that control the normals of the 3D objects, and this determines the way in which light is reflected from the object, thus giving the illusion that a object has a certain texture. In Sacred 2 the map files are DDS format which is a DirectDraw Surface file from Microsoft. These files are made by designing it over an unwrapped 2D version of a 3D model, the model is then re-wrapped together with the map file, to result in the file object.
