You can also use this tool to convert any controller track to a simple keyframed
track. You can convert rotation tracks to either Euler or TCB, and collapse
Position and Scale tracks to either Bezier or Linear controllers.
You can collapse an entire track, or collapse a range of frames within a track
by setting the Start and End frames. A Samples parameter lets you define how
many frames will be placed between keys.
Collapse Controller can be used to collapse any number of selected tracks at
once.
This functionality is similar to the Collapse button found in the Collapse
Transform group of the Motion panel >
Trajectories rollout on page 3121.
WARNING If you are using a Path constraint with the Follow option, using Collapse
Controller to collapse the position and rotation tracks will not preserve rotation
properly, because additional rotation is applied 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.
Procedures
To collapse a procedural controller track:
1 In a viewport, select an object with a procedural controller, then
right-click and choose Curve Editor from the quad menu.
The Track View – Curve 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.
The Collapse Controller dialog appears.
3 Change the Samples to specify the number of frames between keys.
The default value of 1.0 creates a key for every other frame, which might
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 will not display function curves.
5 Click OK.
