Learn to create and animate highly controllable characters using After Effects. In this course, author George Maestri covers every step on the way, from designing the characters in Photoshop or Illustrator, or drawing them straight from After Effects; assembling characters with hierarchies; making realistic deformations with the Puppet tool; automating rigs with expressions; creating realistic head turns; and showing advanced techniques such as using null objects as bones. Finally, the course shows how to perform a basic animation with the character and ensure the rig works correctly.
