The vertical center of mass t rack Dynamics Blend parameter is
set to 1 for both keys (white squares) in the first jump, and to
.5 in th e second jump.

A walk cycle will not activate this value. The biped
has to b e airb orne, then the Lift and Touch vertical
keys will display a Ballist ic Tension value.
If there are more than three vertical keys during a
support period, you can also edit Ballistic Tension
for the lift-off key; otherwise Biped uses the
same value for touchdown and lift-off, since it is
assumed that there is only one vertical dip in the
motion. Low values are high tension (less dip in
the trajectory). Default=0.5; Range=0 to 1;

Use controls on the Keyframing Tools rollout
to clear animation on a biped or selected parts,
mirror biped animation, and cause the Neck to
rotate in body space rather than parent space. You
can also bend the horizontal center of mass track
around a selected horizontal key.
