説明
Bake root motion from foot contact, then sculpt the path in the viewport.
Long description (Overview)
AIN Root Motion Baker is an Unreal Engine editor plugin for converting in-place animation to Root Motion, and for editing existing Root paths without leaving the editor.
It samples foot planted, slide, and airborne motion to generate a Root Translation curve, then lets you sculpt that path in the Persona viewport. Use it for motion matching trajectories, walk / run / jump Root Motion, in-place turns, Pelvis-to-Root extraction, and IK cleanup after Root edits.

Auto Curve — Analyze foot planted / slide / airborne segments and auto-generate a Root Translation curve
Manual Curve — Extract existing Root motion as a Transform Curve, then edit it in Persona with RMB Edit Mode (gizmos, Soft Radius, curve editor)
Detailed Editing Tools — Comprehensive trajectory and speed sculpting features including Smooth Speed, Straight Path, Ease Speed, Ease Rotation, Scale Distance, Scale Speed, Normalize Speed, Arc Path, and Align to Path
Turn — Rotate Root Yaw only to a target angle over a frame range, while keeping Translation
Extract Pelvis — Move Pelvis translation / Yaw onto Root and compensate Pelvis and IK
IK Remap Only — Rekey IK bones only, leaving Root / Pelvis unchanged (IK Snap)
Batch multiple Anim Sequences with the same settings
Undoable Bake (does not auto-save or check out packages)
How to use
Enable the plugin, then open Tools > AIN Tool > Root Motion Baker
Add Anim Sequences and confirm Root / Pelvis / Foot bone names
Choose a Bake Mode → Generate Curves (Auto / Manual) → edit if needed → Bake
In Persona, verify Enable Root Motion / Trajectory, then Save
