Locked authoring and synchronization reliability update

Inverse Kinematics Mappings

Keep IK target bones consistent with authored deform-bone changes without replacing the project's procedural IK system.

Pose Overlay 1.0.2 UE5.8

What The Mapping Solves

Pose authoring can move deform bones while a project’s IK target bones still reflect the original animation. Pose Overlay mappings provide three explicit ways to keep those targets consistent with the authored result.

Three Modes

Mode Behavior Use
Apply Authored Delta Synchronization bakes the authored deform-bone delta into a normal target pose track. The target should receive the authored correction as part of the synchronized overlay.
Follow Composed FK The final IK Targets pass moves the target from the final composed FK source. The target must follow the fully composed result after stacking and relevant upstream pose work.
Follow Composed FK Relative The final pass preserves the incoming source-to-target transform while following the final composed source. The relative offset intentionally belongs to the incoming source animation.

Create A Mapping

  1. Choose the source deform/FK bone.
  2. Choose the target IK bone.
  3. Select the mode.
  4. Choose copied Translation and/or Rotation.
  5. Set Weight.
  6. Validate and synchronize.

Two-Handed Weapon Grip

  1. Map hand_r to ik_hand_gun with Follow Composed FK.
  2. Map hand_l to ik_hand_l with Apply Authored Delta.
  3. On the second mapping, enable Solve Driven Limb and choose hand_l as the Driven Deform Bone.
  4. Leave Weight at 1 for exact reachable contact. Keep stretching disabled unless the intended rig permits arm stretch.
  5. Synchronize after authoring the support-hand grip in every relevant State and Aim point.

Synchronization makes the overlay-authored ik_hand_l track authoritative. The final node follows the weapon-hand anchor, then solves the named hand chain to that already-composed authored target. Upstream Aim, source motion, and clavicle motion therefore remain present while the reachable hand endpoint stays on the authored grip.

Do not use Follow Composed FK Relative for this recipe unless the incoming animation’s existing IK offset is deliberately the grip authority. A bad or unrelated incoming target will otherwise be preserved by design.

Project Boundary

The optional grip constraint is one narrow two-bone chain solve. Pose Overlay does not replace terrain placement, foot IK, full-body solving, socket or weapon-component alignment, or other project procedural IK.
