Why we like it

E Motion earns its place in the blender_extensions library for consolidating driver time remapping, curve editing, onion skinning, and interpolation into a single Graph Editor tab.

What is E Motion?

E Motion is a Blender animation add-on from Eridanus-Epsilon, built around motion editing and curve manipulation. After installation, its tools live under an E_Motion tab in the N panel of the Graph Editor, with a Drivers mode for time expression editing and an FCurves mode for curve tools and glow effects.

Driver variable time remapping supports time expression editing with real-time preview in the Graph Editor and automatic driver variable caching. Curve editing tools add a glow effect, one-click deletion of empty curves and all modifiers, and jumps to animation start and end points. A grid curve editor handles grid-based manipulation and Bezier editing, while onion skinning shows previous and next frames with custom caching. Advanced interpolation covers nonlinear types such as noise and sine, and trajectory visualization displays object motion paths. The interface supports Chinese, English, Japanese, and Russian.

Version 0.4.0 is compatible with Blender 5.0 and newer and is released under the GNU General Public License v3.0 or later. It requests file read and write permission for bezier presets, cache, and trajectory data on disk.

Who is E Motion best for?

E Motion is best for animators handling character animation, physics simulation animation adjustment, complex curve animation design, game animation optimization, and film and video effects animation.

How much does E Motion cost?

E Motion is completely free to download and use.

Frequently asked questions

Does E Motion work with Blender 5.0?

E Motion lists compatibility with Blender 5.0 and newer, so a current Blender install should run it. The add-on's tools appear under an E_Motion tab in the N panel of the Graph Editor once installed. The documented version is 0.4.0, released on 2026-03-27, which focused on security fixes and code consolidation. For the exact supported versions and any later updates, check the developer's page before installing.

Where do I find E Motion's tools after installing?

E Motion places its tools in an E_Motion tab within the N panel of the Graph Editor after installation. From there, a Drivers mode handles time expression editing for driver variable time remapping, while an FCurves mode gives access to the curve tools and glow effects. The add-on also includes a grid curve editor for precise, grid-based operations and onion skinning tools for referencing previous and next frames. These modes group the main editing features in one panel.

What license is E Motion released under?

E Motion is released under the GNU General Public License v3.0 or later, and it is listed here as free. The add-on comes from developer Eridanus-Epsilon, and the documented version is 0.4.0. The GPL v3.0-or-later license governs how you can use, modify, and redistribute the add-on's code. Because licensing terms and availability can change, check the developer's page for the current details before you rely on them.

What file permissions does E Motion request?

E Motion requests a single permission: file read and write access on disk. It uses this to read and write bezier presets, cache, and trajectory data. Version 0.4.0 added the missing files read and write permission declaration in the manifest, since bezier preset JSON was being written without a declared permission. That release also removed all eval() calls to comply with Blender Extensions security policy. For full details on what the add-on stores, review the developer's page.

What interface languages does E Motion support?

E Motion supports interface languages in Chinese, English, Japanese, and Russian. You can switch between them in the add-on preferences, so the panel labels match the language you prefer. This multi-language support sits alongside the core motion editing and curve manipulation tools. If you need a specific language, confirm it is present on the developer's page for the version you install.
