Modifying existing animations?

I'm not sure I can explain the significance of MovementSpeed correctly; it affects:
1) the speed of the movement animation per "step".
2) how many times the animation should play, depending on the animation speed, until the creature reaches the desired square.

By the way, you mentioned earlier that the new animation doesn't work well in cutscenes; is that still the case?

I said that the cavalry unit's movement animation loops incorrectly in Max, and it's even worse in Maya; yes, it's still the same.
