MOTN
The MOTN file format contains the animations for models based on their node structure.
This format can be found in various PKS files and in the motion.bin file.

Sequence Data Table
The sequence data table consists out of two offsets (each unsigned 32bit) per sequence.
Both offsets point inside the sequence data segment.
The first offset points to the main sequence data containing the key frames.
The second offset points to some unknown data array.
Sequence Name Table
The sequence name table consists out of the offsets (unsigned 32bit) to the strings and the strings themself.
The amount of names is given by the sequence count inside the header.
The strings are zero terminated/seperated.
Sequence Data

| Position | Length | Type | Description |
|---|---|---|---|
| 0x00 | 0x04 | uint | Flag (decides the byte size for the block 2 and block 3 entries) |
| 0x04 | 0x02 | ushort | Block 1 end offset/Block 2 start offset |
| 0x06 | 0x02 | ushort | Block 2 end offset/Block 3 start offset |
| 0x08 | 0x02 | ushort | Block 3 end offset/Block 4 start offset |
| 0x08 | 0x02 | ushort | Block 4 end offset/Block 5 start offset |
Block 1
The first block contains the descriptions for the structure of the keyframes.
Each entry in the block is 2 bytes in size.
| Bit-Mask | Description |
|---|---|
| 0xFE00 | Node ID/Bone ID? |
| 0x0100 | First X? channel available |
| 0x0080 | First Y? channel available |
| 0x0040 | First Z? channel available |
| 0x0020 | Second X? channel available |
| 0x0010 | Second Y? channel available |
| 0x0008 | Second Z? channel available |
| 0x0007 | Unknown |
Block 2
The second block contains for each channel the amount of data points (key frames?).
Each entry in the block is 2 bytes or 1 bytes in size depending on the flag.
Block 3
The third block contains unknown data.
Each entry in the block is 2 bytes or 1 bytes in size depending on the flag.
Block 4
The fourth block contains the same amount of data as the second block.
Each entry in the block is 1 bytes in size.
Block 5
The fifth and last block contains the actual data for the keyframes.
Each entry in the block is 2 bytes in size and could be interpreted as degrees.
