Create Multiple Footsteps Dialog: Walk 993
Walk gait is selected. You can only clear Alternat e
when Run or Jump gaits are sele cted.
Number of Footsteps—Determines the number of
new footsteps to be created.
Par amet ri c S tr ide W idt h—Sets the stride width as
a percentage of the pelvis width. A value of 1.0
produces a stride width equal to the pelvis width.
Avalueof3.0producesawide,waddlingstride.
Changes to this setting automatically change the
Actual Stride Width.
Parametric describes the para meter in terms of
biped anatomy, and Actual describes the value i n
3ds Max units.
Stride Width=1 and Stride Width=3
Actual St ri de W idth—Setsthestridewidth
inmodelingunits. Changestothissetting
automatically change the Parametric Stride Width.
Total Dista nce—Displays the tota l distance the
footsteps will travel with the current settings. This
valuecannotbechangeddirectly.
OK —Creates footsteps with the c urrent sett ing s .
Cancel—Cancels footstep creation.
Default—Resets the values on the dialog to default
values.
Timing group
Auto T imi ng—Sets timing parameters
automatically. Auto Timing affects the
following timing parameters for the Walk gait:
•Walkfootstep,DoubleSupport
When Auto Timing is selected, these parameters
are automatically adjusted to reasonable values.
Control the footstep sequence by adjusting
theStrideLengthandTimeToNextFootstep
parameters.
When Auto Timing is off, you can control the
footstep sequence by adjusting the gait ti ming
parameters, but you can’t change the Time To
Next Footstep parameter .
Interpolate—Control acceleration or deceleration
of the series of footsteps. When this box is selected,
a second set of step parameters under L ast Step
is enabled.
Biped creates footsteps star ting with the va lues of
the parameters under First Step and ending with
the values of the parameters under Last Step.
By interpolating b etween the two, Biped produces
a footstep series that changes over tim e.
When Interpolate is cleared, the Last Step
parameters are grayed out. Biped creates all the
footsteps using only the parameters under First
Step.
Sta r t A ft er La st Footstep—Appends t he newly
created footsteps to the end of the existing footstep
sequence.
Start at Current Frame—Inserts the newly created
footsteps at the cu rrent frame after the existing
footstep sequence, allow ing you to make a gap in
time before the footsteps start again.
First Step and Last Step groups
Para met ric S t rid e Leng th —Sets the stride leng t h for
the new footsteps as a percentage of the length of
thebiped’sleg.Thedefaultvalueof0.75givesan

A value of 1.0 will produce a stride length equal
to the leg length, which ma kes the biped stretch
slightly to reach the next step. A value of 0.0 will
