Find /fonline_sdk/Client/data/art/intrface/default.ini in your SDK directory.
Find this:
GmapTilesPic = WRLDMP%02d.FRM # Íàçâàíèå èçîáðàæåíèé ãëîáàëüíîé êàðòû
GmapTilesX = 4 # Êîëè÷åñòâî èçîáðàæåíèé â øèðèíó
GmapTilesY = 5 # Êîëè÷åñòâî èçîáðàæåíèé â âûñîòó
WRLDMP%02d.FRM is the image file of the worldmap. The actual image is located in SDK\Client\data\art\intrface folder.
.png also works.
You can edit the # of tiles for the map both Wide and High in config.fos in the server/scripts folder (note: Not SDK values shown)
__GlobalMapWidth = 20; // Maximum 100
__GlobalMapHeight = 15; // Maximum 100
__GlobalMapZoneLength = 74; // Maximum 500
Also in: worldmap.fos
#define ZONE_COUNT_X ( 20 )
#define ZONE_COUNT_Y ( 15 )
#define ZONE_LENGTH ( 74 )
Zone Length is how many pixels for each grid square, which if you want grid squares you will have to add to the image manually.
The values must match in both files, and the actual WM image must be the correct Height and Width for the values you choose. Otherwise it'll look goofy.
You must also make a relief map. Explanation in here:
