You can combine accelerator keys, like Ctrl and Alt, with left, middle, and right
mouse buttons to extend or stretch the range displayed in the track bar.
You can expand the track bar to display the keys on function curves. From
there, you can select and manipulate keys.
Biped Curve Editing in Track View
The same function-curve editing controls are found in Track View. Track View
has two modes: Curve Editor and Dope Sheet.
character studio displays function curves for biped components in the Track
View - Curve Editor.
Dope Sheet mode displays the footstep tracks and other biped keys as boxes.
Here, you cut, copy, and paste keys to create repeated motion. You can use
Time Editing in Dope Sheet mode, and cut, copy, paste, and insert time
segments, complete with keys, into your animation.
Curve display can help pinpoint troublesome spots in your animation. You
can see where a curve has problems, often corresponding to motion problems
in the viewport animation. You move the keys to compensate for the problems.
Understanding the Workbench
The Workbench is a curve editor customized for use with character studio. It
provides specialized tools for selecting and displaying curves, and also for
locating and fixing errors and discontinuities in motion. It is a visualization
tool that allows you to see and manipulate quaternion function curves
represented as euler angles. Also you can see curves for the the position of a
biped body part in any coordinate space.
The Workbench automatically limits selections to biped body parts and scene
objects related to that biped. You can analyze these selections for errors using
a variety of detectors, and correct them using the provided fixers. You can
also apply filters to perform operations on different biped body parts to affect
the overall animation without error identification.
Function Curve editing for Biped is also available in the 3ds Max Track View
- Curve Editor and in the expanded track bar, but without the specialized
Workbench tools.
Especially when working with imported motion-capture data, you might find
that curve editing is difficult using the standard 3ds Max tool set. This difficulty
can arise from the fact that motion-capture data often has a key on every
