About IK Hierarchy Chains

Before we go any further, a word about IK chains. There are three types of chains:

Single Chains
Direct Chains
All Chains

Single Chains

The single chains are the most basic of chains. A single chain is a straight line with no secondary chain attached. It goes up to the first intersection.

Direct Chains

A direct chain is a single chain which goes directly to the core (root).

All Chains

All chains are attached and move together when one part is moved.
