Working with the Workbench 1009
Wo rkbench Wo rkflow
Here are the overall steps you would follow to
use the Workbench to analyze and fix a biped for
problems
1. Create your animation and play it. Visually
note anything that jumps out at you as being
wrong or incorrect.
2. With the biped selected in the v iewport, open
the Workbench by clicking the Workbench
button in the Biped Apps rollout on the Motion
panel.
3. Select the biped body part that seems to have
the problem. You can select it in the viewport,
or from the list in the Select panel.

For example, all the objects in a leg or an ar m
share a single track.
4. On the Analyze panel, choose an analyzer from
the drop-dow n list. S et the analysis conditions,
then click Analyze. Any errors the analyzer
encounters will be displayed in a list at the
bottom of the Analyze panel. The Curve view
also indica tes the problem area by displaying
averticalbar.
5. On the Fix panel, select the errors you want
to fix. Select the filter for the fix, adjust its
parameters, and then click Fix Selected. You
can select the errors one at a time, or in any
combination. You can sort the errors by time
or body part, depending on what kind of fix
is needed.

If the results aren’t satisfactory, try changing
the p arameters and fixing again. Repeat the
process until you find the combination of
parameters t hat correct the movement. Or try a
different fixer or filter (these are described later
in this topic).
Ani mati on Wor kbench Tools
The Animation Workbench provides three t ypes
of tools to use with biped animation: analyzers,
fixers, and filters.
Analyzers
These are used to find out-of-the ordinary
properties in your animation. Certain analyzers
parse the waveform of your motion tracks and
detect variation from the curves. There are two
detectors available that do this; Noise and Spike.
There a re also analyzers for finding and fixing
knee conditions, specifically knee wobble and
extension.
For more information, see Analyze Panel (page
2–1017).
Fixers
Fixers address problems found by the analyzer.
The fixers work by running a specified operation
over just the ana lyzer result. They don’t change
the complete animation, just areas around the
problem.
For more information, see Fix Panel (page 2–1020).
Filters
Filters are operations that are per formed on the
specified animation tr acks. Unlike fixers, they
affect the complete specified t ime interval, not just
the ana lyzer result.
The Rot Smoothing, Rot Blurring, Rot Boosting,
AdvRotSmoothing,PosSmoothing,PosBlurring
and Pos Boosting filters are all variants of one
