Wmx.obj is world map geometry model only. Contains 835 segments, does not contain textures nor additional info like general header or pointers. Collision is calculated directly from faces. Towns and places on map are part of world map and are created the same way as mountains, ground etc. File size is 0x9000*835. Every 0x9000 a next segments starts.

Block = contains geometry

1-768 segments are final world map. 769-835 are story based segments like Balamb garden stationary, no Esthar, No cities in DISC4.

In FF8's world data, a segment location is predefined in currently unknown place (in engine or wmset.obj) and there are horizontally 32 and vertically 24 segments to form the world map. Each block in segments follows to same logic with 4x4 grid instead of 32x24. The first block starts from the upper left corner of the segment.

Each block have their own local bounding box, which the vertice values follow. A blocks origin is always predefined to start from upper left corner of its bounding box. This bounding box is always a size of 2048x2048 units (up and down limit is not known). This means that 2048 units or 0x800 is the local max for vertices coordinate before it overlaps with next blocks bounding box. There are no limitation to overlapping, you can extend a blocks geometry out of its bounding box and even out of the local segment. However, the collision is always calculated from the block which bounding box you are in, so extending a blocks geometry out of its bounding box doesn't make it collidable in overlapping block.
