Select a biped. > Motion panel > Biped Apps rollout > Mixer > Motion Mixer menu bar > Transitions > Edit
The Mixer Transition Editor controls transitions on transition tracks. When it is active, you view transitionary stick figures to aid in placing your transitions. You can use this dialog to change the start and end times of transitions, change the transition focus, and perform other functions.
This dialog is very similar to the Motion Flow Transition Editor.
Length—Sets the number of frames for the duration of the transition.
Transitions are calculated by matching velocities in both clips. Smooth out abrupt velocity changes using longer transitions.
Ease In—Ease-in value for the source clip.
Ease Out—Ease-out value for the destination clip.
Transition Focus—Lets you specify a focus point on the biped where the transition takes place. The Mixer will attempt to match movement based on this selection. For example, if Left Foot is selected, the transition will use the left foot as a focal point during the transition, aligning the motion of the left foot in both clips as much as possible during the transition. Default=Auto.
-
Auto—The transition focus is calculated by averaging the overall position of the biped as it transitions from one clip to the next.
-
Center Of Mass—The transition focus is based on the center of mass position of the biped as it transitions from one clip to the next.
-
Left Foot—The transition focus is based on the left foot position of the biped as it transitions from one clip to the next.
-
Right Foot—The transition focus is based on the right foot position of the biped as it transitions from one clip to the next.
-
Both Feet—The transition focus is based on an averaged foot position of both of the biped's feet as it transitions from one clip to the next.
Note: The best way to see the differences between the transition foci is by watching the yellow and red ghosts.
Preserve Height—When turned on, Preserve Height will allow gradual vertical motion to accumulate from the source to the destination clip. For example, climbing stairs will loop upward. If it is turned off, the next clip is always set so that its lowest point is at z=0. This default insures that motion does not gradually float up (or down) with each additional clip.
Angle—Sets the direction of the destination clip.
The angle of the destination clip is automatically set for best body fit between the two clips when the Start Frame values change. Use Angle to change the direction of the destination clip.
Previous Transition—Go to the previous transition in the transition track.
Displays the previous transition in the Transition Editor, moves the time slider to the start frame of the previous transition and highlights the previous clip in the transition track.
Next Transition—Go to the next transition in the transition track.
Displays the next transition in the Transition Editor, moves the time slider to the start frame of the next transition and highlights the next clip in the Scripts list.
Optimize Transition—Displays the Transition Optimization dialog.
Options in the Transition Optimization dialog allow you to search for the location for the transition.
Go To Start Frame—Moves the time slider to the first frame of the transition.
The number field shows the start frame number.
Start Frame—Set the transition start frame for the source and destination clips in their respective fields. Duration for the source and destination clips displays above the Start Frame fields.
Rolling—Keeps the clip in motion during the transition.
Fixed—For the source clip, this option freezes the biped at the Start Frame position during the transition. For the destination clip, this option freezes the biped at the End Frame position. If Fixes is chosen for both the source and destination clips, the transition is a gradual interpolation from one frozen pose to another.
Set Start Frame—Copies the value in the Frame field of the Ghost area to the Start Frame field in the Clip area. The position of the destination clip changes to match the biped body in the destination clip to the biped body in the source clip.
Locate an appropriate start frame for the source and destination clips by using the Frame spinner and viewing the positions of both stick figures, then click Set Start Frame.
The destination clip is rotated and positioned to match both bipeds. Use the Angle spinner to reorient the destination clip.
Frame—Use the Frame spinner to scrub a stick figure back and forth, which allows you to determine a start frame for the source and destination clips. Visual feedback of the stick figures is a good way to judge which start frames are needed for the source and destination clips.
