The FTEX texture format is a format for textures which appears as a subfile of a BFRES file.

Header (FTEX)

Every FTEX file begins with an 0xC0 byte FTEX header.

Offset Size Description
0x00 4 "FTEX" File identifier, ASCII string.
0x04 4 Unknown has value 0x01 in examined files. May be version number.
0x08 4 Texture Width. Width of the texture in pixels.
0x0C 4 Texture Height. Height of the texture in pixels.
0x10 4 Unknown has value 0x01 in examined files. May be a count of some form.
0x14 6 unknown
0x1A 1 Unknown seems related to the format.
0x1B 1 Texture Format. Values unknown.
0x1C 8 unknown
0x24 4 Data Length. Length of texture data in bytes.
0x28 0x88 unknown
0xB0 4 Data Offset. Offset to the texture data. Relative to this field.
0xB4 4 Mipmap Offset. Offset to the mipmap texture data. Relative to this field. 0 if not present.
0xB8 8 unknown
0xC0 End of FTEX header

Incomplete header documentation. Last 8 words (32 bytes) seem to change per file. Offset 160 (dec) from FTEX header always seems to be zero, followed by a single byte (value of 1), 3 padding bytes, then a relative offset to the string table, then a relative offset to UnknownDataA, a relative offset to UnknownDataB, a relative offset to unknown DataC, and then two more unknowns (usually zero).
