esteban, check to see how far from the origin you are in max

well…i think its maxes TCB rotation controller thats acting up here. There is a bug in it, and in some points, inparticular between the frames the models may flip and so on. Try settings your tcb rotation controller to smooth.

tcb is a type of rotation controller used by default in max. If you go to the curve editor, and under the node which is responcible for the rotation of your model find rotation right click on rotation and go assign controller and you will find options there, try smooth rotation.
