Need help with deciphering an .ani file for Shaiya

[Reign]

Can anyone open this so I can see what is in it ? This is the last file in Shaiya Online that cannot seem to me modded. If someone can crack this format to where it can me edited, I will pay a bounty.

See attached file for an example.

This is the structure of the file.
Not sure if I'm right with the variable names (probably not).

Code: Select all

short unknown1
short unknown2
short frame_size
short unknown3
short number_of_bones

for (number_of_bones) {
	int parent_bone_index
	float[16] bone_coords

	int number_of_rotation_keyframes
	for (num_rot_kf) {
		int timestamp
		float x
		float y
		float z
		float w
	}
	
	int number_of_translation_keyframes
	for (num_trans_kf) {
		int timestamp
		float dx
		float dy
		float dz
	}
}

short = 2 bytes
int/float = 4 bytes

Here's a part of your binary file converted to ASCII (structured and commented by me):
