TSCB

Terrain scene binary (TSCB) files describe terrain areas layout and terrain materials.

TSCB File Specification

Header

Offset (h)	Size	Data Type	Description
0x00	4	String	TSCB file signature (magic) `54 53 43 42` or "TSCB"
0x04	4	Unsigned Int	TSCB version? `0A 00 00 00` or "10.0.0.0"
0x08	4	Unsigned Int	Unknown.
0x0c	4	Unsigned Int	file_base table relative offset
0x10	4	Float	Unknown 500.0
0x14	4	Float	Unknown 800.0
0x18	4	Unsigned Int	material_info_array length (number of elements in the array)
0x1c	4	Unsigned Int	area_array length (number of elements in the array)
0x20	4	Unsigned Int	Probably padding
0x24	4	Unsigned Int	Probably padding
0x28	4	Float	world_scale used by area_array for tile size
0x2c	4	Unsigned Int	Unknown (`00 00 00 08`)

The float values in 0x10 and 0x14 seem to be related to the size of the playable map area. The in game playable map is -5000.0 to 5000.0 along the z-axis and -8000.0 to 8000.0 along the x-axis. While 500.0 and 800.0 do not exactly map to those values, they do seem to be related.

Material Information Array

Header

The material information header is one value, the section size. This includes the index table and the value table.

Offset (h)	Size	Data Type	Description
0x00	4	Unsigned Int	Material info section size in bytes

Material Information Array Lookup Table

Following the header is a table of relative offsets to each entry in material_info_array

Offset (h)	Size	Data Type	Description
0x00	4	Unsigned Int	Relative offset to array entry

Material Information Value Table

Each entry in the array contains an index and four attributes

Offset (h)	Size	Data Type	Description
0x00	4	Unsigned Int	Array index (mat_index)
0x04	4	Float	Unknown. values range from 0.03-0.59.
0x08	4	Float	Unknown. values range from 0.03-0.59.
0x0c	4	Float	Unknown. values range from 0-1.
0x10	4	Float	Unknown. values range from 0.2-1.63

Area Array

Area Array Lookup Table

Following the material information section is a table of relative offsets to each entry in area_array

Offset (h)	Size	Data Type	Description
0x00	4	Unsigned Int	Relative offset to array entry

Area Array Value Table

Each entry contains meta data for one tile in the terrain scene. There are multiple levels of detail (LOD) for the terrain.

Entries range from 0x30 to 0x54 depending on the size of extra_info_array

Offset (h)	Size	Data Type	Description
0x00	4	Float	X Position
0x04	4	Float	Z Position
0x08	4	Float	Scale?
0x0c	4	Float	area_min_height_ground
0x10	4	Float	area_max_height_ground
0x14	4	Float	area_min_height_water
0x18	4	Float	area_max_height_water
0x1c	4	Unsigned Int	Unknown. Usually 0, 1 or 2
0x20	4	Unsigned Int	file_base. Relative offset to file base name string
0x24	4	Unsigned Int	Unknown. Usually 0.
0x28	4	Unsigned Int	Unknown. Usually 0.
0x2c	4	Unsigned Int	ref_extra. It seems to be a flag to indicate if there is an attached extra_info_array

Extra Information Array

if ref_extra does not equal 0 there is an extra_info_array attached to this area. The array is 4 or 8 values long.

Every area includes a .hght and .mate file. The extra_info_array indicates if there is an additional .water.extm and / or .grass.extm file

Offset (h)	Size	Data Type	Description
0x30	4	Unsigned Int	extra_info_array length. Number of elements in array.
0x34	4	Unsigned Int	Unknown. Usually 20 or 3.
0x38	4	Unsigned Int	Unknown. Usually 0, 1 or 3.
0x3c	4	Unsigned Int	Unknown. Usually 0 or 1.
0x40	4	Unsigned Int	Unknown. Usually 0 or 1.
0x44	4	Unsigned Int	Unknown. Always 0.
0x48	4	Unsigned Int	Unknown. Always 3
0x4c	4	Unsigned Int	Unknown. Usually 0 or 1.
0x50	4	Unsigned Int	Unknown. Always 1.
