AFK AI for Unity: Auto-rig package for the editor

Rig and animate a model without leaving Unity. Pick a model in your project, click Rig, and about a minute later a rigged copy with its animation clips sits next to the original, ready to play.

    A rigged FBX appears next to the original, Humanoid for a person, with its clips set to loop or play once.

Install

  1. Download afk-ai-unity-0.1.0.tgz and put it somewhere it can stay, such as your project's Packages folder: Unity installs the package from that file.
  2. In Unity, open Window > Package Manager, click + at the top left, choose Add package from tarball... and pick the file.
  3. Open Window > AFK AI.

The package runs only inside the Unity editor. Nothing of it goes into your game builds.

Requirements

  • Unity 2021.3 or later, Unity 6 included, on Windows, macOS or Linux
  • An afk.ai account: you sign in with Google. A free account gets 3 rigs a month.
  • An internet connection: the rigging happens on AFK AI's servers.

Use it

  1. In the AFK AI window, click Sign in. Your browser opens afk.ai: sign in with Google there, then go back to Unity. The window shows your email and how many rigs you have left this month.
  2. In the Project window, select a model file: .fbx, .glb or .gltf. A model you've placed in the scene works too: the plugin sends the file it came from.
  3. Choose its Body type, then All animations for the rig and every animation for that body type, or Rig only for just the skeleton. Leave Facing on Auto.
  4. Click Rig. The window shows the progress: uploading, rigging, adding the animations, downloading. Closing the window doesn't stop it.

If the browser can't get back to Unity (some security software blocks it), afk.ai shows a sign-in code instead. Open I have a sign-in code in the AFK AI window, paste it, and click Use code.

Each rig uses one of your account's rigs, the same as on afk.ai/rig. A free account gets 3 a month, with the free animations; a plan gives you more rigs and every animation. A rig that fails doesn't count.

What you get back

Where
Hero_rigged.fbx next to Hero.fbx, selected and highlighted in the Project window. The original isn't touched.
People
A human comes in as Humanoid, so its animations can be shared with your other Humanoid characters, and theirs with it.
Everything else
Animals, creatures and objects come in as Generic.
Clips
Each animation is its own clip. The ones that repeat, like Idle, Walk and Run, are set to loop; one-off clips like Jump and Death play once.
What AFK AI makes, in 3D: the model on a skeleton made for its body type, with its skin weights painted and its animations. Drag to turn it, and pick an animation to play. Knight: Medieval Knight by Andy Woodhead, CC BY 4.0.

Limits worth knowing

  • The plugin sends the model's own file, as it is: an .fbx, a .glb, or a .gltf with everything embedded, up to 50 MB.
  • If Unity can't match a human's skeleton to its Humanoid bones, the model comes in as Generic. Its animations still play; they just can't be shared with other Humanoid characters.
  • Stop waiting stops the wait in Unity, not the rig, which still counts. If the connection drops, Try again picks up the same rig and never counts it twice.

Questions

Does it work in Unity 6?

Yes. It works in Unity 2021.3 and later, Unity 6 included.

Does anything go into my game builds?

No. The package is editor-only. Your game gets only the rigged model and its clips.

Can I rig .glb files?

Yes. Unity only shows .glb and .gltf files as models when a glTF importer package is installed, but the plugin can send them either way. The rigged copy comes back as an FBX.

An animation loops when it shouldn't. How do I change it?

Select the _rigged.fbx, open the Animation tab in the Inspector, pick the clip, change Loop Time and click Apply.

Is AFK AI for Unity free?

It's free to download. Each rig uses one of your afk.ai account's rigs, the same as on afk.ai/rig: a free account gets 3 a month, with the free animations, and a plan gives you more rigs and every animation. A rig that fails doesn't count.

Does my sign-in end up in my files?

No. Your sign-in is kept on your computer, in your own user settings, never in a scene or project file, so sharing or committing your work never shares your account. Sign out forgets it.

Can I use the result in a commercial game?

Yes. The animations are CC0 (public domain), and your model stays yours.
