Animation Import Assistant - Retargeting & IK for Godot

Preview, retarget and clean up animation inside Godot.

Animation Import Assistant combines side-by-side motion preview, humanoid bone mapping, manual IK cleanup and native animation-library export in one editor workspace.

Free with optional donations. By APERMAN. Public beta 0.1.0, tested with Godot 4.7.1 on macOS.

Features

• Preview: play, pause, loop, scrub, change speed and orbit both characters.
• Inspect: bone overlays, rest poses, editable mappings and import diagnostics.
• Retarget batches: compatible humanoid rigs, clip naming, loop settings and duplicate-name handling.
• Manual IK cleanup: foot-contact intervals, fixed hand targets, knee/elbow poles, offsets, strength, edge fades and optional ankle/wrist orientation locking.
• Compare and bake: toggle before/after corrections, then bake enabled IK at 30 fps.
• Export: native AnimationLibrary resources, reusable presets, attach to a selected character and last-export recovery.

Downloads and setup

Addon: copy addons/animation_import_assistant into your project and enable it under Project Settings / Plugins.

Full demo: open project.godot, choose the Animation Assistant tab and click Load practice assets. Includes our original Pip and Mira robots, idle/walk/wave examples and a dedicated practice scene.

Both packages include an illustrated six-page PDF guide and detailed Markdown instructions. The original robot assets are CC0. A silent 40-second feature tour is also available as an MP4 download.

Beta scope

Inputs must already be imported into your project: GLB, glTF, FBX or Godot scenes, with one Skeleton3D per input and compatible mapped bone ancestry. Exports skeletal position, rotation and scale tracks; non-bone tracks are omitted with diagnostics.

This tool does not create bones or skin weights, detect contacts automatically, move the pelvis to reach targets, or provide terrain-following IK at runtime. Different rest poses and proportions may need work in a 3D editor. Review each exported clip.

License and feedback

Commercial project use and modification are allowed. Redistribution or resale of the plugin, source and documentation is restricted. See LICENSE.txt for full terms. Project outputs remain subject to the rights in your input assets. The original demo assets have separate CC0 terms.

For bugs, leave a comment with your Godot version, input format, reproduction steps and diagnostic message. Share only assets you have permission to distribute.
