2.
In the Curve Editor’s Controllers window ,
select the track you want to collapse. Then
choose Controller > Collapse Controller from
the Tr ack View menu.
TheCollapseControllerdialogappears.
3. Change the Samples to specif y the number of
frames between keys.

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 . R otation tracks collapse to
either Euler or TCB.
Note: TCB controllers w ill not display function
cur ves.
5. Click OK.

keys, as does the Track View – Dope Sheet.
Tip: If you want to collapse the controller into a
weighted list controller, turn on Add To New

Inter face
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 range of
animation to be collapsed. Default=The last frame
of the orig inal controller’s active r ange.
Wa rn in g: If you choose a range of frames smaller than
the original range, the animation within 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.
Collapse to—Sets the type of controller the
procedural track will become:
•
B ezier or Euler Controll er— When this is chosen,
Position,Scale,andscalarparametertrackswill
be assigned Bezier controllers. Rotation tracks
w i ll be assigned Euler controllers.
•
Linea r or TCB Control ler—When this is chosen,
Position,Scale,andscalarparametertrackswill
be assigned Linear controllers. Rotation tracks
w i ll be assigned TCB controllers.
Note: TCB controllers will not display function
curves.
Add to New La yer—When this is turned on, the
collapsed controller is added as a new layer in a
weighted
list controller (page 2–326) .Default=off.
This option is useful b ecause it keeps the old
controller on another layer with a weight of 0.0.
This lets you restore the original animation easily
if you need to.
