Tutorial 6: Working with Motion Capture Data

Lesson 4: Editing with Layers

You'll import a file and use layers to add changes. The motion file is a sprinting motion. You'll add a layer and rotate the center of mass so the character is running on a wall.

Loading in the motion

  1. Create a biped.

  2. On the Motion Capture rollout click Load Motion Capture File.

  3. Load jez.sprint.csm.

  4. On the Motion Capture Conversion Parameters dialog, click OK.

    No Footstep Extraction and No Key Reduction are both chosen. The motion file loads with keys at every frame.

  5. Click Play to see the running motion.

Adding a layer

The following steps illustrate the use of Snap Set key to alter the runners original position.

  1. On the Layers rollout, click Create Layer.

    A layer is created.

    At frame 8, the character's left foot is just touching down.

  2. Turn on Animate.

  3. On the Track Selection rollout, click Body Rotation.

    This selects the center of mass rotation track.

  4. In a viewport, click and drag to rotate the center of mass 90 degrees about the X axis.

  5. Click Play.

    The character is running on an invisible wall.

  6. Move the time slider to frame 0.

  7. On the Layers rollout click Snap Set Key.

    The character snaps to his original position.

  8. Move the time slider to frame 16.

    The right foot is just touching down.

  9. On the Layers rollout, click Snap Set Key.

    The character snaps to his original position.

  10. Click Play to view the animation.

    The character runs on the ground, then on the wall, and back to the ground again.

    To improve the effect you can rotate the spine objects and stretch the legs to make it appear that the character is jumping on the wall.
