The Viewer tab overlays a Controls panel on top of the canvas. It’s split into three groups:
Animation Controls
- Animation — selects which Spine animation is playing.
- Skin — selects which Skin is applied.
- Speed — playback speed multiplier (0.1× → 3.0×).
View Controls
- Reset View — restores default camera/layout positioning.
- View Options — numeric offsets used to position the comparison view: Spacing X / Spacing Y (distance between original/optimized) and Offset X / Offset Y (global shift).
Debug Controls
- Debug Mode — enables debug rendering overlays (depends on runtime support).
- Enable Physics — toggles physics simulation (if the skeleton uses physics).
- Labels — toggles labels overlay.
