AnnoMotion Skeleton

8 min 3D & Animation Free

Make, rig and animate 3D models in one place. Create a model from a description or from photos, take the plain humanoid body Skeleton builds for you, or open a 3D model you have already made — then fit a skeleton to it in your browser, animate it on a timeline and export a rigged, animated glTF with engine presets for Unity, Unreal and Godot, or render it out as a 2D sprite sheet. The editor runs client-side and is free; the optional AI auto-rig and generating a model from a description or photos spend credits, and the full motion preset library — walk, run, jump, pick up, attack — comes with any subscription, with five animations free to everyone.

Before you start
Nothing — describe a model or start from photos, take the starter body, or open one of your own models.
What you end up with
A rigged, animated glTF with engine presets — or a 2D sprite sheet rendered from it.

Step by step

  1. Start a project

    Skeleton opens on your project library. Press Describe it or From photos on the Create a 3D model card and the model is generated onto the stage, which spends credits — or press Start with a mannequin for the plain humanoid body Skeleton builds for you, or start from any model you have made. When a model is on the stage, the Look it over card shows its size and files.

  2. Prepare, then fit and weight the skeleton

    In Prepare, press Fix all to straighten the model. In Rig, fit the joints and Apply the rig so it paints the skin weights. There is an optional AI auto-rig that does this step for you — it spends credits, as does generating a model from a description or photos.

  3. Animate on the timeline

    Key poses on a timeline, or drop in motions from the Motion library. Chain another clip on to join clips one after another into a longer sequence.

  4. Export

    Export a rigged, animated glTF with a preset for Unity, Unreal or Godot — or render the animation out as a 2D sprite sheet instead.

Worth knowing

  • The editor is free and runs in your browser. The optional AI auto-rig and generating a model from a description or photos both spend credits, and the full motion preset library comes with any subscription — five animations are free to everyone.
  • Export glTF, not FBX: skinning and animation survive glTF reliably from a browser.
  • Chaining clips is how you build a full move set from short presets rather than animating one long timeline.
  • Animating a prop rather than a character? Switch to Object mode (press 4) and move, turn and scale the whole model as one piece — no skeleton needed.
  • Clay view shows the model in plain grey with its polygons drawn, so you can judge its shape and density without the textures. It never changes what you export.
  • Works on a phone or tablet too: drag to orbit, pinch to zoom, and tap a joint — or press and hold on it — to select it. Detailed joint work and weight painting are easiest with a mouse, and your project is saved, so you can finish on a computer.
