i am animating a character using skeletal animation with matrixes for each bone. when i test rotating any part of the body but the root everything moves fine but when i try to rotate the root the entire body starts spinning very fast. i am testing this by itself so there aren''t any other things being drawn that could affect it. does anyone have any idea what may be happening?

Perhaps you are applying a rotation over and over again - that is when you draw the first time you rotate by theta and dont reset the matrix then on the next update rotate again and so on.

I don''t think that''s it because i keep the original list of vertices for the model as they are and use them as a reference.
