The layout
Section titled “The layout”| Area | What it holds |
|---|---|
| Toolbar (top) | Menu, undo/redo, ▶ Play, the Setup / Animate switch, the tools, Bone / Part, the pick filter, + Add, mute, View, shortcuts and ⚡ Connect MCP |
| Skeleton (left) | The tree of bones, slots and attachments, with search, eyes (visibility) and locks; below it skins, images, audio, animations, events and state machines |
| Viewport (centre) | The artboard. Wheel zooms, Alt/right-drag pans, F fits. Grid, rulers and guides, snapping, background and onion skin are in its corner |
| Inspector (right) | Properties of whatever is selected: the document, a bone, slot, attachment, constraint, sound or bus. Preview shows the result as shipped, Outline lists everything |
| Timeline (bottom) | The dopesheet or graph of the current animation, the State Machine editor and the Scripts panel |
Every panel can be dragged to another side or grouped with others, and ☰ Menu → Layout saves your own layouts.
Setup and Animate
Section titled “Setup and Animate”- Setup mode builds the rig: bones, slots, attachments, constraints and their rest values (the setup pose).
- Animate mode (` toggles) records keys. With ● Rec on, any change you make at the playhead becomes a key in the current animation; the Inspector’s ◆ buttons key one property.
| Tool | Key | Use |
|---|---|---|
| Select / rotate | V | Click to select, drag to rotate bones (or parts, in Part mode) |
| Translate | T | Move bones and attachments |
| Scale | S | Scale; Shift for uniform |
| Pose (IK) | I | Drag a bone and its parents bend to follow |
| Create bone | B | Drag from a parent bone to add a child |
| Mesh | M | Edit mesh vertices; in Animate mode, free-form deformation |
| Weights | W | Paint how much each bone moves each vertex |
| Pen | N | Draw bezier paths and bounding-box outlines |
| Compensate | J | Move a bone without moving its children |
Bone | Part decides whether dragging a picture moves its bone or the picture itself. Pick filters what a click can grab. A hover outline always shows what the next click will select.
The View menu switches between the normal view, bones only, mesh wireframes, the Order view and the 3D view.
