In the Content Browser, select {targetMeshName}. Right-click it and choose Scripted Asset Actions > Create Animation Override. Unreal creates {overrideAssetName} as a data asset.
Select {overrideAssetName}. Set Config to {targetConfigName} and confirm that Character Mesh references {targetMeshName}.
Right-click {overrideAssetName} and choose Scripted Asset Actions > Retarget Animations.
In the Retargeting section, set IKRetargeter to {ikRetargeterName}. Confirm that Source Mesh and Target Mesh resolve to the intended skeletons. Review {retargetAssetSummary} under Animations and Anim Blueprints, then click Retarget.
Choose the project-owned {resultFolderName} folder when the retarget window asks where to store the generated assets. Keep generated files outside the imported pack content.
After retargeting completes, select {overrideAssetName} again and run Scripted Asset Actions > Update Override. This refreshes the Animation Overrides and Anim Blueprint Overrides maps with the generated replacements.
Open {characterBlueprintName}. Select its Mesh component and set Skeletal Mesh Asset to {targetMeshName}.
Then select the Gameplay Animation component (AC_GameplayAnimation) and add {overrideAssetName} under Overrides. Save the Blueprint. The override list should contain the new asset as shown in the final state.
Prepare {skeletonAssetName} before retargeting. The procedural animation uses these virtual bones to position the hands and weapon, track elbow targets, and read camera motion.
Open the Skeleton and find the parent bone in the Skeleton Tree. Right-click it, choose Add Virtual Bone, and select the target bone. Rename the new entry to match the table, including Unreal's VB prefix.
Add the bones in this order so VB ik_hand_gun exists before you create its children. The parent provides the reference space; the target is the bone the virtual bone follows.
| Virtual bone | Parent | Target |
|---|---|---|
{bone.name} | {bone.parent} | {bone.target} |
Keep existing entries if their names, parents, and targets already match. Save the Skeleton before continuing.
; Use your character mesh with the pack's movement, weapon actions, and procedural animation. Start with a duplicate of `BP_SciFi_Character`; this guide calls it `BP_ProjectPlayer`. The example mesh is `SKM_Operator`; use your own mesh and a compatible IK Retargeter. ## 1. Add the virtual bones

## Check the result
Play as `BP_ProjectPlayer` and test idle, movement, aiming, weapon switching, and reloading. The hands should follow the weapon through each action. If the pose is wrong, check the virtual-bone names and targets, the retargeted layer classes, and the override assigned to **Gameplay Animation**.
