Create K ey s for Ina ctive Footsteps—Activates
all inactive footsteps. Activat ion creates default
keys for any footsteps that do not have them. If a
footstep does not have keys, it is displayed as bright
green (right foot) or bright blue (left foot). After
keys are created for the footsteps, the footsteps
change color to pastel green and pastel blue.

Deactivate Footsteps—Removes the body

A pasted footstep is inactive until it overlaps a like foot and

Paste Footsteps—Pastes footsteps from the
footstep buffer into a s cene. The footsteps appear
inactive in the scene. Move them so they overlap
the active footsteps. When a footstep turns red,
mouse up and the pasted footsteps will activate.
Wa rn in g: If any footstep in the buffer overlaps in time
with a footstep previous to the one onto which you
are pasting, a message ap pears and the paste is not
performed. This can occur if the first footstep you are
pasting and the original footstep you are pasting onto
both have
double support periods during the same
duration of the footstep. The second pasted footstep
and the footstep prior to the one you are pasting onto
may overlap in time.
