Adjusting Track Weight 619
Tip:
If you aren’t sure where you want the
transition to take place, you can choose Search
Entire Clip. This option can place the t r ansition
anywhere in the two clips. Check the motion
afterward to ensure the transition takes place
at an appropriate time.
To change the focus on a foot -based t ra nsiti on wit h
Biped animation:
1.
Scrubthetimeslidertothemiddleofthe
transition.
2. Zoom in on the feet in any viewport.
3. Right-click the transition and choose Edit from
the pop-up menu. Alternately, you can select
the transition and choose Transitions > Edit
from the Motion Mixer menu.
The transition editor appears. In addition, two
stick figures appear in viewports to show the
bipeds’ positions in the two clips. The yellow

4. On the dialog that appears, choose a different
Transit ion Focu s f rom the list .
As you change the Transition Focus, you
w i ll see the foot positions change. The
Transition Focus sets a center or focal point
for the transition, chang ing the biped’s
position slig htly depending on the setting. On
foot-based transitions, try differe nt settings
to bring the yellow and red skeletons closer
together on a planted foot.
Note: Transitions involving planted feet often
result in one or both feet sliding when they
should stay planted. After setting up the
transition, you can correct this problem with
amixdown. SeeExporting Animation to the
Biped (page 2–624).
Adjusting Track Weight
Each track has one or more weight c ur ves (page
3–1033) that you can use to mix motion from
several tracks to varying degrees. The weight curve
determines how much a specific tr ack contributes
to the motion within the trackgroup.
With weight curves, you can create several full
or partial transitions between all the tracks in
a trackgroup. Compare w ith transitions on a
transition track (page 3–1027), w hich can only
create a full transition between two clips.
