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 | Dim. Indicates the "shape" of a given surface or texture (see this page). |
| 0x08 | 4 | Texture Width. Width of the texture in pixels. |
| 0x0C | 4 | Texture Height. Height of the texture in pixels. |
| 0x10 | 4 | Depth |
| 0x14 | 4 | numMips |
| 0x18 | 4 | Texture Format. Go to line 589 on this page for explanation and format values. |
| 0x1C | 4 | AA Mode. Indicates the AA mode (number of samples) for the surface (see line 865 here). |
| 0x20 | 4 | Usage. Indicates how the given surface may be used (see this page). |
| 0x24 | 4 | Data Length. Length of texture data in bytes. |
| 0x28 | 4 | unknown |
| 0x2C | 4 | mipSize |
| 0x30 | 4 | unknown |
| 0x34 | 4 | Tile Mode. Indicates the desired tiling mode for the surface (see this page). |
| 0x38 | 4 | Swizzle Value |
| 0x3C | 4 | Alignment |
| 0x40 | 4 | Pitch |
| 0x44 | 0x6C | 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).
