Footstep Mode Dialog 853
Convert to Footsteps dia log
Generate a k ey per frame—Creates a key at every
frame, and extracts footsteps based on foot
IK Blend values equal to 1. Save Segment in
Motion Flow mode stores the active script as a
.
bip file without footsteps. The biped foot keys
are assig ned IK Blend values of 1 for the or iginal
footstep keys. After loading a
.bip file saved using
SaveSegmentinMotionFlowmode,useConvert
(on the Biped rollout) to extract footsteps.
Convert is also useful if you have already converted
from footsteps to freeform in which case the feet
are assigned an IK Blend value of 1 for the k eys
that represented footsteps.
Flatten Footsteps to Z=0—The entire biped is
repositioned to place the footsteps at Z=0.
Note: An IK Blend value of 1 for the feet puts
them into world coordinate space and prevents
them from slipping while setting biped keys in a
freeform animation.

Right-click anywhere in the Footstep track in Track
View (Dope Sheet) to display the Footstep Mode
dialog. This is a modeless dialog a nd can remain

This dialog allows you to:
• Control the duration information displayed
w ith the footsteps.
• Create a freeform period between footsteps.
• Selecttherightorleftedgesoffootstepblocks

Edit Footsteps—In this mode (which is the default),
you can edit the biped’s footsteps to change their
duration; start and end frames; airborne duration;
and so on.
Ed it Fre e Form ( n o phys ics ) —In this mode, you can
edit the biped’s body keys for the frames at which
the biped is airborne.
Free Form suspends the physically based dynamics
that normally control biped motion. This is
essential when you want to make the biped fly ,
or sit down, or fall over. Note that the freeform
period must be between footsteps.
