destination clip that the transition starts; a value of 80, for example, starts the

transition at frame 80 of the destination clip. In this example, the source clip

plays from 0 to 60, there is a 10 frame transition from frame 60 of the source

clip to frame 90 of the destination clip (frames 80 to 90 cover the destination

clip transition period), then the rest of the destination clip plays.

When the Transition Editor displays, the first things to try, before manually

editing the transition, are the Optimized Transitions. Optimized transitions

use a minimum foot sliding algorithm. The top right-hand corner of the

Transition Editor dialog is the icon for optimized transitions. If the optimized

transition is not satisfactory, try editing the transition manually.

Manual transition editing offers the most control; the Frame spinners in the

Ghost areas of the Transition Editor allow you to scrub the source and

destination clips while viewing two stick figures. Find a good start frame in

both clips using the Frame spinners. Things to look for in both clips are similar

supporting feet, body momentum that will appear natural, and arm motion

similarities. If velocity changes between the clips are too abrupt, use the Length

field to adjust the duration of the transition.

On the Motion Flow rollout, click Save File to save your work as an MFE file;

transitions and scripts are saved. These BIP files contain no footsteps. Biped

foot keys are saved with an IK Blend value of 1 for footsteps. To extract

footsteps, exit Motion Flow mode, use Load File on the Biped rollout, and

then click Convert. Convert looks at foot IK Blend values of 1 to extract

footsteps.

TIP The location of any referenced BIP file is saved in the MFE file. If the BIP file

cannot be found, a Missing Motion Flow Files dialog opens up respectively, in

which the missing files are listed. To rectify this, open the Asset Tracking dialog

on page 7100 and set a new path of the missing files.
