Edit Your Blender Animations Just Like Editing Mesh With This Free Tool
No need to switch to the Graph Editor and manipulate F-curves.
With J4m1ns' Editable Motion Paths, the motion of any bone or object is displayed as an editable curve: keyframes become points, and their tangents become Bezier handles. You can use familiar Edit Mode tools like snapping, extrude, knife, and bevel to manipulate motion intuitively. Every adjustment updates the underlying F-curves in real time, so you don't need to switch to the Graph Editor.
It works directly with your existing rigs, including bones, constraints, IK, drivers, and animation controls. No setup, no rig modifications, no baking required. Editable Motion Paths has been tested on Blender Studio's production rig, Rain, and the developer claims it's production-ready and non-destructive.
J4m1ns is also very open about the development process, explaining that they're not a programmer and relied heavily on AI to help develop Editable Motion Paths. It's free and will stay free. "The add-on itself has no network access and no AI inside; the only file it writes on its own is a view render, when a script asks for one."
- Shape the motion where you see it. Click a key on the path, drag it, turn its handles, or select a few and press G, R, S. Location, Rotation, Scale, and Value paths; rotation keys get axis rings like Blender's gizmo; several bones at once; Global, Local, or Camera space.
- Draw the timing. A dot per frame shows the spacing; the speed graph and the timing chart can be dragged: pull a key's speed down for a slow-in, set the reach with the mouse wheel, right-drag to smooth out bumps. The path keeps its shape, and the keys stay on their frames.
- Sculpt it. The Sculpt Motion Path tool has brushes for the shape (Grab, Smooth, Pinch) and the timing (Slow, Fast, Even) – and Dissolve: one stroke over baked or mocap motion removes every key the path doesn't need.
- See what the motion does. Onion-skin ghosts of the whole character update while you edit; the path can be colored by speed or by a jitter heat map; the center of mass shows whether a pose is balanced.
- Animator tools built in. Easing presets with a live preview (P), Breakdown, Moving Hold, Scale Time, Offset Cascade for overlap, Shift Phase for cycles, Clean Up for baked keys, F-Curve modifiers as a stack, paths to curves and back.
- Knife, bevel, loop cut, extrude – on the motion, like on a mesh.
Editable Motion Paths is compatible with Blender 4.4 and newer. You can download the add-on from the official Blender Extensions platform.
Blender 5.3 is officially here, bringing native support for 3D Gaussian Splats, a DLSS denoiser, native dispersion support in the Principled BSDF, and more. Check out our article for a closer look at all the new features and improvements.
