hght files describe the heightmap of the main field and add-on content field.

hght files only contain a table of height data. There are 65,536 (256 × 256) unsigned short entries in the table.
Each file describes a 256 × 256 mesh tile. Each tile has placement data found in MainField.tscb.
Each entry in the table maps to an x, y and z component. The height or y component of each vertex is the value read the from the file.
struct hghtData {
ushort height;
};| Offset | Length | Type | Description |
|---|---|---|---|
0x00 |
2 | Unsigned Short | Vertex y component |
x and z can be calculated, while iterating through the data table:
for (int index = 0; index < 256 * 256; index++) {
uint x = index % 256;
uint z = index / 256;
}Note that z is expected to be an integer quotient. The floor function can be used if integer division is not supported.
