Here's the minimal structure of the body animation tracks for a TRAM file (address stored at 0x34 in the dat) | Here's the minimal structure of the body animation tracks for a TRAM file (address stored at 0x34 in the .dat). The example below is for '''SHINZOMidle1''': those bone tracks are found at 0x480020 in the original level18_Final.raw. The global structure is 19 bone tracks, preceded by a list of their offsets (the "header"). | ||

'''N.B.''' An animation with frame count 10, like the above '''SHINZOMidle1''', also has a ''duration'' of 10 game ticks which extends 1 tick past the final rotation keyframe. If an intermediate pose needs to be calculated during the final tick (e.g., during slowmo), it will be interpolated between the final keyframe of the current animation and the first keyframe of the following animation. In the case of '''SHINZOMidle1''', the rotation pose is exactly the same throughout the animation, so the pose during the last tick of an idle loop will be constant as well (apart from the height shift). | '''N.B.'''
