NodeMonkey has released Motion Painter, a Blender add-on that allows for creating object animation by drawing motion paths directly in the viewport instead of keyframing manually on the timeline.
With the tool, a painted stroke becomes an editable guide, which the add-on then converts into standard Blender location and rotation keyframes.
The tool includes several viewport tools: Motion Paint for freehand strokes, Motion Polygon for straight or connected segments, Motion Eraser, and Motion Select, along with a set of built-in brushes such as Follow, Orbit, Wave, Push/Pull, and Explosion. Each of them produces a distinct motion behavior. Artists can also stack and blend multiple paths, apply rotation behaviors like Follow Direction or Spin, and link guides to native Blender curves for further manual editing.
