NOTE If the animation you are saving is unkeyed world-space animation (as opposed to IK or FK), turn off Animated Tracks when you save. 1 On the Map Track To Track rollout on page 7089, map the motion tracks of the incoming character's root to the current character's root. For example, if you are retargeting a Biped on page 4147 onto another, you would map the incoming Biped object's position and rotation tracks onto the current Biped. 2 Map the rotation tracks of the incoming character's limbs onto the current character's limbs. There is one exception here: if a hand (for example) is going to use IK in the current scene, either don't map it at all, so you can animate it later, or if you are mapping from an FK model to an IK model, map the Exposed World Transform to transfer the incoming FK trajectories to current IK controls. 3 Go to the Retargeting rollout. 4 In the Scale Origin group, choose both the Incoming and Current root objects. If the characters are symmetrical and have the same proportions, you can now choose all the mapped tracks in the Retargetable Nodes list. If the characters are not symmetrical, or their proportions are different, then you need to take further steps. 5 In the Derive Scale Between Chains group, choose the Start and End nodes of both Incoming and Current chains to correspond to either the left or right leg of the character: for example, Thigh to Toe. Read the Scale Factor that is set on the basis of the two chains. 6 Click Set to retarget the highlighted mapped tracks. If the two current legs are not the same length, repeat step 5 for the other leg, then choose that leg's Foot (or Toe) node, turn on Enabled in the FK Retargeting Extent group, and choose the top of the leg (for example, Thigh) as the parent to use. Click Set. 7 Save the retargeted mapping file. 8 Click Load Motion to animate the current character, and then close the Map Animation dialog. 7092 | Chapter 23 Managing Scenes and Projects
