Bouncing Ball

First and foremost, we must have the ball bounce in place and later have the ball move from the left, up-high to the right, down-low.
First make the ball move in Z axis:

Mocap Data Cleaning

Body mocap will often lead to situations of hip and foot sliding along with various abnormal limb jittering.

Fix for the Hip Sliding
  • Sample out the torso keys to linear data and convert to curve data.
  • Use Refine Key to down sample the curve data into a manageable amount of keys.
  • Use the Curve Editor and the Transformation Gizmo to inspect the abnormal sliding and direction.
  • Use the Scale tool in the Curve Editor to fix the sliding issue.


Fix for the Foot Sliding
  • iClone Reach Target can be seen as a type of Lite IK effector, thereby, just attach two spheres to the ankles and use the IK Constraint.
  • Use the Lite IK effector to fix the sliding in the steps.
  • Review and compare the final result with the original movements.

Smooth Camera Movement
  • Camera can now be set to Default key tangent for animation. (Default Key Tangent, see here)
  • New and old key comparison
Usage


Linear


Curve
