Collapse Controller 523
Collapse Controller c an be used to collapse any
number of selected tracks at once.
This f unctionality is similar to the Collapse button
found in the Collapse Tr ansform group of the
Motion panel > Trajectories rollout (page 2–301).
Wa rning: If you are using a Path constraint with the
Follow option, using Collapse Controller to collapse t he
position and rotation tracks will not preser ve rotation
properly, because additional rotation is a pplied by the
Path constraint. If you want to collapse this kind of track,
use Collapse in the Collapse Transform group of the
Motion panel > Trajectories rollout instead.
Procedure
To collapse a procedural controller track:
1.
In a viewpor t, select an object with a procedural
controller, then right-click and choose Curve
Editor f rom the quad menu.
The Track View – Cur ve Editor is displayed.
2. In the Curve Editor’s Controllers window,
select the track you want to collapse. Then
choose Controller > Collapse Controller from
the Track View menu.
TheCollapseControllerdialogappears.
3. Change the Samples to specify the number of
frames between keys.

other f rame, which mig ht be more than you
want to work with.
4. Select the type of controller that you want the
keys to use after collapsing.
Position and Scale tracks collapse to either
Bezier or Linear. Rotation tracks collapse to
either Euler or TCB.
Note: TCB controllers w ill not display function
cur ves.
5. Click OK.

collapsed animation. The track bar displays the
keys, as does the Track View – Dope Sheet.
Tip: If you want to collapse the controller into a
weighted list controller, tur n on Add To New
Layer . The original controller will be stored on
a layer with a weig ht of 0.0. It wi l l have no effect,
but w ill be available for future use, if need be.
Interfa ce
Start Frame—Sets the first frame of the range of
animation to be collapsed. Default=The first
frame of the original controller’s active range.
End Frame—Sets the last frame of the r ange of
animation to be collapsed. Default=The last frame
of the original controller’s active r ange.
Wa rn in g : If you choose a range of frames smaller than
the origin al range, the animation w ithin the range will
be collapsed, and the remaining motion will be discarded
unless Add to New Layer is on.
Samples—
Sets the granularity of the collapse
operation. This value defines the number of
fram es between keys. Default=1.0.
