footsteps. When creating freeform animations,
you should set your leg keys to IK Blend=1.0
during the periods you want the feet to be
planted, and set the move keys to IK Blend=0.0.
This will insure that the feet are locked and

Inter face
ConverttoFreeformdialog
Generate a k eyframe per frame—Creates keys at
every frame.
Note: Converting footsteps to freeform creates
foot IK Blend values of 1 for the biped feet for the
original footstep keys. This s implifies keyframing
by putting the feet into world coordinate space,
which prevents them from sliding when the biped
is moved. These foot IK Blend values are also used
when you click Convert (on the Biped rollout) to
convert back to footsteps.
Convert to Footsteps dialog
Generate a k ey per frame—Creates a key at ever y
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 assigned IK Blend va lues of 1 for the orig inal
footstep keys. After load ing a .bip file saved using
SaveSegmentinMotionFlowmode,useConvert
(on the Biped rollout) to extrac t 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 keys
that represented footsteps.

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.
