About This Package
Runtime IK for s&box. Drop a component on the end bone of any rigged model (hand, foot, head, tail) and it works: no per-model setup files, no bone-name markup, no assumed axis convention.
- TwoBoneIK - arm/leg IK with pole vector control.
- LookAtIK - single-bone look-at (head/eye aim), clamped to a maximum angle.
- FootPlacementIK - ground conformance (foot planting + pelvis drop) on top of TwoBoneIK.
- FabrikIK - unconstrained variable-length chain IK (tails, tentacles, ropes).

Summary:
Runtime IK for s&box: two-bone limbs, look-at, foot placement, and FABRIK chains, zero setup.
Description:
Better IK gives any skinned model working, stable runtime IK: TwoBoneIK (arms/legs with a proper pole vector), LookAtIK (clamped head/eye aim), FootPlacementIK (ground conformance and pelvis drop on top of TwoBoneIK), and FabrikIK (unconstrained variable-length chains for tails, tentacles, ropes) - all computed analytically every frame. Drop a component on the relevant bone; it walks the skeleton to find the chain automatically, works on Citizen or any custom rig, and layers on top of the animgraph instead of fighting it.
