HGHT

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

Height map of Hyrule Main Field

HGHT File Specification

hght files contain no header or signature.

hght File Layout

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.

Height Map Data

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.

Offset (h)	Size	Data 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;
}
