From what I can tell, the first value is a number of vectors. The vectors are in [X,Y] dword (one word each) pairs. They're based on the center of the model and Y is easy to predict what it'll do (it adds that value to the character's Y center and points the vector there), but the X value is very peculiar. It can become a square or star shape with the right values. I'm not sure how changing one affects the others, but it's like it is a triangle list. It's divided into 8, then 6, then 8, then 6 vectors separated by 0s.
The second part seems to be colors, but changing them didn't seem to make a difference.
Someone feel free to check it out further.
