Pitch— When on, accumulates the pitch (Y) angle
during the transition. When off, the angle is
simply blended with the next clip. Default=on.

Default=on.
Sub-Blends group
In order for other world-space objects to transition
within the space of the velocity blend or a child of
the velocit y blend, you need to specify a sub-blend.
For example, think of a rig that has a root moving
through world space, and a lso has world-space IK
foot controls. In this case, you would pick the root
as the velocity blend, then select the root in the list
and add the foot controls as its sub-blends. The
result of this will be the that root makes a smo oth
transition and the feet make as smooth a transition
as possible in the direction that the legs are going
(w ithin the root’s space) at t r ansit ion time, not in
the direction that the feet themselves are going at
transition time.
Sub-B lend Nodes li st—Displays the objects chosen
for sub-blending.
Select Velocity Nodes—Click to display a Pick
Nodes dialog (page 2–641) and choose the objects
to sub-blend.
Before you pick sub-blend nodes, you must first
choose a velocity blend node in the upper list.
Typically this is the parent of the nodes that will
be sub-blends.
Delete Velocity Nodes—Click to delete the
highlighted objects from the list.
Set Other Transition Veloci ty Nodes—Copies
the set of velocity sub-blend objects to a ll other
transitions in the current t rack.

Optimize Transition—Displays the Transition
Optimization dialog (page 2–641).
Options in the Transition Optimization dialog
allow you to search for the location for the
transition.
Impor tant: If you use velocity blending, pick your blend
objects before you optimize the transition.
