Better IK
Released
Runtime IK for s&box: two-bone limbs, look-at, foot placement, and FABRIK chains
BetterIk/SandboxBoneNode.cs
Adapter type that wraps an engine BoneCollection.Bone and exposes the IBoneNode interface for the BetterIk skeleton resolver. It delegates name and parent access to the underlying Bone and constructs parent adapters as needed.
