EvilEngine/ANIM

Format

Offset	Type	Description
0x00	char[4]	Magic bytes. Always "SKB1".
0x04	int	Unknown
0x08	short	numBones. Number of bones in the model.
0x0A	short	numFrames. Length of the animation in frames. The length in seconds can be found as the last entry in the frameTimes array.
0x0C	int	numKeyframes. Combined total of the number of keyframes set for each bone.
0x10	int[3]	Unknown
0x1C	Keyframe[numKeyframes]	keyframes. List of all keyframes in the animation. A Keyframe defines the position, rotation, and scale of a bone at a specific frame in the animation.
-	float[numFrames]	timeMap. A list of timestamps which map each frame of the animation to a time in seconds. Usually this starts at 0 and goes up by an interval of 0.01666 (1/60) or some multiple of 0.01666. This can be used to change the speed of an animation or stretch any particular frame across a longer or shorter amount of time than the rest of the frames.
-	KeyframeMap[numFrames - 1]	keyframeMaps. A list of KeyframeMaps for each frame of the animation. A KeyframeMap assigns each bone to a specific keyframe in the keyframes array. How exactly the bones are assigned is not entirely known yet.
