Using In Place Mode to Adjust Keyframes
In Place Mode is a good way to adjust keys on a biped that already has
animation applied to it. Rather than scrolling the view at different frames to
keep a running biped visible, turn on In Place Mode. Now when you scrub
the time slider, or use the Next Key and Previous Key buttons, the biped
remains visible. A key that needs adjustment can be quickly spotted and
corrected.
TIP Judging lateral center-of-mass motion using In Place mode is difficult. In Place
mode limits center-of-mass motion on the XY axes; all sense of body momentum
on these axes is suspended during playback. You might want to turn off In Place
playback to gain a sense of lateral momentum when setting or adjusting horizontal
keys (Body Horizontal Track) for the center of mass.
Procedures
To use In Place mode to adjust keyframes:
1
Select a biped that has animation, and go to the Motion panel.
2
On the Biped rollout, click the bar
at the bottom to expand the rollout.
(If the rollout is already expanded, the bar shows a minus sign at the left,
instead of a plus.)
3
In the Modes group, click In Place Mode to turn it on.
4
At the bottom of the3ds Max window, turn on Auto Key.
5 Find a frame where the biped needs adjustment, and modify or add keys.
Trajectory Display
When a biped is animated, you can view its motion not only using Biped
Playback, but you can also see the path, or trajectory, the biped (or selected
biped links) follows throughout the motion.
