| - | The transform structure details the frames in which a transformation of the bone occurs (i.e. translate, rotate, or scale) and by how much the bone moves between frames with respect to the scale of the model (transform factor).Transform structure is repeated for instances [<color #5724ff>cc cc</color>] before introducing the next element header where [<color #5724ff>cc cc</color>] = Data Count. The first two bytes of data contain two bits representing unknown values and fourteen bits which determine the frame of a transformation. | + | The transform structure details the frames in which a transformation of the bone occurs and by how much the bone moves between frames with respect to the scale of the model (transform factor).
