Redirecting the motion within a clip
Motion capture data can be used in a variety of ways. You can redirect the
motion of a character using the same motion capture data. The Redirect tool
allows you to alter the original animation for a character by modifying its
path or orientation at any time during its animation. The Redirect tool does
this by offsetting the translation and rotation attributes for the selected
character.
For example, you can change the start or end point of a character’s animation
by redirecting the character’s starting position or by redirecting its motion
during the animation. You can redirect a character in an existing animation
sequence in the scene or a character associated with a clip within the Trax
Editor.
In the steps that follow, you redirect the skeleton to turn to the right while
walking. The workflow for the redirection is as follows:
■ Scrub forward in the animation to determine a location in the clip where
you want the character to turn. A realistic choice is where the ball of the
skeleton’s right foot is planted on the ground plane because this accurately
simulates how a real person might turn.
■ Select the entire skeleton. In this example, selecting the entire skeleton
selects it at the root joint (the top node of the skeleton’s hierarchy)
Selecting at the root joint ensures that the entire skeleton gets redirected
when the redirection control is applied.
■ Create and position a rotation redirection control using the Redirect tool.
■ Keyframe an initial starting rotation for the redirection control.
■ Rotate the redirection control so the skeleton faces the new direction of
travel.
■ Keyframe the second rotation for the redirection control.
