FTXP files (caFe TeXture Pattern) are texture pattern animation files found into BFRES files. It contains animation data about which texture that should be rendered at what time. Unless otherwise noted, all offsets in the file are relative to themselves.
Header
The file starts with a 0x38 bytes long header.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | File magic. Always FTXP in ASCII. |
| 0x04 | Int32 | Name offset. The name of this file. |
| 0x08 | Int32 | String table end. |
| 0x0C | UInt16 | Flags. |
| 0x0E | UInt16 | Number of user data. |
| 0x10 | UInt32 | Number of frames. |
| 0x14 | UInt16 | Number of textures. |
| 0x16 | UInt16 | Number of material targets. |
| 0x18 | UInt32 | Unknown. |
| 0x1C | UInt32 | Unknown. |
| 0x20 | UInt32 | Unknown. |
| 0x24 | UInt32 | Unknown. |
| 0x28 | UInt32 | Unknown. |
| 0x2C | Int32 | Material array offset. |
| 0x30 | Int32 | Texture index group offset. The groups points to FTEX filenames and FTEX headers. |
| 0x34 | Int32 | User data index group offset. |
Material
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt16 | N = Number of samplers. |
| 0x02 | UInt16 | Unknown. |
| 0x04 | UInt32 | Unknown. |
| 0x08 | UInt32 | Unknown. |
| 0x0C | UInt32 | Name offset. Points to the name of this material into the string table. |
| 0x10 | Sampler reference[N] | Sampler references. The offsets are relative to 0x10 in this structure. |
Sampler reference
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt32 | Sampler offset. Relative to the end of the material structure. |
| 0x04 | UInt32 | Unknown. Probably an offset to something else. |
Sampler
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt16 | Unknown. |
| 0x02 | UInt16 | Unknown. |
| 0x04 | Int32 | Sampler name offset into the string table. |
User Data
The user data is stored into different entries, one for each type. The index group points to these entries.
| Offset | Type | Description | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0x00 | Int32 | Name offset. Points to the string which is the name of this user data. | |||||||||||||||
| 0x04 | UInt16 | N = number of entries. | |||||||||||||||
| 0x06 | Byte | Type.
| |||||||||||||||
| 0x07 | Byte | Unknown. Always 0. |
Number
For user data with numbers the data comes directly after the user data header.
String
| Offset | Type | Description |
|---|---|---|
| 0x00 | Int32[N] | N offsets to the strings. The strings are null-termined and comes directly after this array. They're not stored in the string table. |
