i'm trying to balance an "unrelenting force" type combat spell and i've already modified the "get back up" animation to play faster using 3ds max, but i noticed that many times, if the target lands on eneven terrain, he will begin sliding down the terrain and will only get up after he is done sliding, which undoes all my effort at balancing the duration that the target is "stunned".

is there a gameplay setting somewhere that controls friction? or would prevent this sliding effect?
