Calibrating the Mocap Data

 
 
 

After you have applied the mocap data for the face in Face Robot, you're ready to calibrate it. The data from the mocap files drives the animation of the controls on the face in Face Robot.

Calibrating mocap data means adjusting the mocap data that was created for an actor to fit the proportions of the face you have loaded in Face Robot. This way, the facial movements captured in the mocap data will map properly to create the correct expressions on the face in Face Robot.

The calibration data is saved for the head, so you need to calibrate the data only once and then it is calculated when you map other mocap data files to this head.

To calibrate the mocap data

  1. Apply the mocap data and run through it to see where there are problems with the proportions of the face.

    You will probably want to go to frames where the face is in an extreme pose to find problems.

  2. On the Act panel, choose Library Tools Calibrate to open the Calibrate property page.

  3. On this page, set the Scale and Pitch for each of the areas on the Up and Down Direction tabs: Upper lip, Lower lip, Jaw, Nose, and Eyes.

    Pitch is set in degrees and Scale is the scale factor (1 is 100%) of how the normalized data is applied to the face.
