Paste Footsteps—Pastes footsteps from the
footstep buffer into a scene. The footsteps appear
inactive in the scene. M ove them so they ov erlap
the active footsteps. When a footstep turns red,
mouse up and the pasted footsteps will activate.
Wa rning: If any footstep in the buffer overlaps in time
with a footstep previous to the one onto which you
are pasting, a message appears 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.
