Explanation
This file incorporates curves and/or properties for an given embbed model. Because of that, it's almost always certain that they are contained in a file container (dat). There's instances of mots that controlled properties instead of bones, so it's not always certain of what it animates. A further inspection have to be done.
Mot main header
| Offset | Type | Size | Description |
|---|---|---|---|
| 0x00 | uint32_t |
4 | File identifier (Magic number). |
| 0x04 | uint16_t |
2 | Animation's frame count. |
| 0x06 | uint8_t |
1 | Animation's property count. |
| 0x07 | uint8_t |
1 | Loop flag, sets if the animation either loops or not (1/0). |
on Offset 8, The File gives informations about the curves, i.e: what bone it animates, etc.
Curve Info
| Offset | Type | Size | Description |
|---|---|---|---|
| 0x00 | int8_t |
1 | Bone index (-1 means it animates the mode's root bone). |
| 0x01 | int8_t |
1 | Curve property. |
| 0x02 | uint16_t |
2 | Curve keyframe count. |
