Move Shapes shows how to create a simplistic walk cycle using FK in After Effects.
This new tutorial from the Move Shapes channel (Peter Arumugam) shows how you can simplify the rigging and animation of a 2D character to create a walk cycle. The tutorial uses simple parenting, strategically placed anchors, and clever keyframing to build a walk cycle.
Tools like DUIK allow you to create IK chains where you need them. A system typically used for a character’s legs when you animate. If you want to learn more about that process along with the basic animation principles involved in making a walk, check out this tutorial from Evan Abrams.
