Fixers —
Determinesthemethodusedtoattempt
to correct t he errors found by the analyzer. In
general, try to match the fixer to the analyzer
propert y. For example, if you have selected a Noise
detector with Rot Speed, then choose a Fixer with
Rot i n the name as well . The exception to this
wouldbewhenitisobviousthatyou’dpreferto
remove the keys rather than modify them. In that
case, choose a Remove Keys fixer.
Fixer options include:
•
Rot S moothing—Corrects rotational errors
by smoothing the curve. Can be repeated on
thesametrackforgreatereffect. Slowerthan
blurring, but keeps more detail of the curve.
•
Rot B lurr ing—Corrects rotational errors by
blurring the curve. Good if you just want to
keep the general shape of the animation, but
don’t want to keep the details. May remove too
much detail in the animation.
•
Adv R ot Smoothing—Works e ve n better than
the normal smoothing filter when it comes to
only modifying large changes. Can be repeated
on the same track for greater effect. It is t he
slowestfilter,greatatkeepingminutedetails,
which can be very important, especially with
motion-capture data when you want to keep
nuances.
•
Pos S moothing— Corrects move transform
problems by smoothing the curve. Can be
repeated on the same tr ack for greater effect.
Slower than blurring, but keeps more detail of
the curve.
•
Pos Blur ring—Cor rects positional problems by
blurring the curve. Good if you just want to
keep the general shape of the animation, but
don’t want to keep the details. May remove too
much detail in the animation.
•
Remove Keys—Fixeserrorsbydeletingkeys
basedonanintervalsetting.
•
K nee Wobble —Fixe s k nees that wobble or shake
whenafootisplanted.UsesaKneeAnglevalue
as criteria for error status.
•
K nee E x tension—Fixes knees that overextend
whenafootisplanted.UsesaFluctuationvalue
as criteria for error status.
Fixe r parameters
Individual fixers display different parameters.
These include:
•
Width—Determines how much of the curve is
affected around the keyframe.
All the Fixers except for Remove Keys display
this p a rameter.
•
Dampi ng—Determines how the fix is blended
into the existing c urve. Changes how effective
the fixer should be. A hi gher value, the more
dramatic the change. A damping value of 1.0 is
normal behavior
All the Fixers except for Remove Keys display
this p a rameter.
•
Delete K eys —Allows for selective key removal
based on Interva l Width. When Delete Keys is
used, keys are removed only within the Interval
Width. When Delete Keys is not turned on,
Remove Keys will remove the selected keys
without considering the Interval Width.
This parameter is available only when Remove
Keys is the fixer.
•
Interva l Width—Determines the number of
frames around the er ror to consider when
deleting keys.
This parameter is available only when Remove
Keys is the fixer.
•
K nee Angl e— Sets the rotation angle to
determine what constitutes knee extension
errors.
If the k nee is planted and its angle is less than
or equal to the knee limit angle, then the
