Select a biped > Motion panel > General rollout > Save Segment
A modified Save As dialog displays when you click Save Segment on the General rollout of the Motion panel. Special controls are at the bottom of the dialog.
Start Frame: Starts saving at this frame of the named animation.
End Frame: Stops saving at this frame of the named animation.
Active Time Segment: Click to save animation in the active time segment.
Edited Transition Interval: Saves frames in a transition only. Select a clip on the Motion Flow Script rollout, open the Transition Editor and then select Save Segment to activate this control. Game developers can save only the motion in the transition.
Generate a Keyframe per Frame: Saves a key at every frame. Select this check box if you plan to extract footsteps using Load Motion Capture on the Motion Capture rollout. The footstep proximity procedure for extracting footsteps needs keys at every frame to judge foot motion and extract footsteps.
Save Segment in Motion Flow Mode
Use Save Segment from Motion Flow mode, turning off the Generate a Keyframe per Frame check box, to create one .bip file that bridges all of the transitions in a Motion Flow script. Footsteps are not saved; feet are assigned an IK Blend value of 1, with Object turned on for the keys that represent footstep duration. This IK constraint prevents the feet from slipping in a freeform animation. After loading this file, use Convert on the General rollout to extract footsteps. Convert bases footstep extraction on foot IK Blend values.
Note: You can also use Create Unified Motion on the Motion Flow Script rollout to transfer all the animation in Motion Flow Mode into your scene. The animation will then be available when you turn off Motion Flow Mode.
