Any ideas as to why my custom character rig is bouncing?

The custom animations for the rig run fine, but the player is bobbing up and down for no reason! This does not happen if the hip height is 0 or less. However, he is completely submerged in the ground for reasons unknown. Only the torso and the head have "cancollide" set to true.

Sometimes adding a default BodyPosition in the player's torso helps the bouncing. Also, make sure if you're using the new physics that the model parts don't weight too much.
