Animation Tool - HKX Edit

A single standalone tool that takes a Skyrim Havok (.hkx) animation all the way: browse and play it in 3D, pose bones Blender-style, drive limbs with IK, set keyframes on a dope sheet, and export a game-ready HKX — no Blender, no Havok SDK, no converter chains. LE (32-bit) and SE/AE (64-bit) both supported, converted on the fly.

What makes this tool different

• FULL ANIMATION EVENT SUPPORT — every event shown on its exact frame. Add, edit, delete, keep favorites, and export them back into the HKX.

• EVERY CREATURE ANIMATION — humans, horses, dragons, chaurus and more : 40 bundled skeletons with automatic matching cover the whole vanilla bestiary. For viewing AND authoring.

• EVERY PAIRED ANIMATION — killmoves and paired animations auto-detected, both actors playing together — and paired AUTHORING: edit A1 and A2 side by side in the same scene.

• FIRST-PERSON AND THIRD-PERSON — 1st-person rigs load, match, play and edit exactly like 3rd-person ones, from the same library tree.

• VIEW TAB TO EDIT TAB POSE COPY — while an animation plays in the View tab, copy any pose (Ctrl+C) and paste it straight onto your work in an Edit tab. Every frame of every vanilla animation becomes a posing reference.

• ROOT MOTION (AMR) SUPPORT — animations that travel or turn play with their REAL movement instead of sliding in place (toggle in-place <-> actual travel any time). In the editor you author root motion yourself with the ground controller, and it exports AMR-style with the animation.

• ONE TOOL FROM CREATION TO THE GAME — pose (Blender-style G/R), auto/manual IK chains, keyframes and a dope sheet, onion skinning, root-motion editing, then export the finished HKX directly. Nothing else to install.

Editions & how to get it

The tool ships in two editions built from the same program :

• HKX_View (downloadable here) — the viewer edition: everything about browsing, playback, inspection, event editing and HKX export. The authoring engine (pose/IK/keyframes) is not included in this build.

• HKX_Edit (Discord only, for now) — the full edition with the complete authoring pipeline described above. It is currently distributed only through our Discord and will be released publicly here once it has gone through enough testing. Want to create animations today? Join the Discord.

Installation

No requirements. Extract the zip as a whole folder and run the exe.
(First launch may be scanned by your antivirus — a PyInstaller false-positive; whitelist it if blocked.)

Troubleshooting

If an animation does not play correctly (mangled pose, wrong proportions, actors overlapping), the automatic match picked the wrong skeleton — select the correct one MANUALLY in the A1 combo on the left (A2 for the partner in paired animations). ropping the matching skeleton .hkx into the skeletons\ folder also improves the automatic match from then on.

License & credits

This tool is free software released under the GNU GPLv3 — the LICENSE file is included, and the source code is available on request as the GPL requires.

Third-party components (full notices bundled in THIRD_PARTY.md and tools\LICENSES.toml):

This tool contains no Havok SDK code and does not require one.
