E Topology Smooth earns its place in the Blender Extensions library as a Python add-on dedicated to mesh topology smoothing, pairing continuity analysis with curve fitting and shipping builds for every major platform.
E Topology Smooth is a Blender add-on from Eridanus-Epsilon focused on mesh topology smoothing. It combines G0–G4 continuity analysis with multi-algorithm curve fitting, giving Blender users a way to work on mesh topology smoothing inside the editor. The add-on is written entirely in Python.
Distribution covers a broad set of platforms. Builds are available for Windows x64, Windows Arm, macOS Intel, macOS Apple Silicon and Linux, and the add-on targets Blender 5.1 and newer. Installation follows Blender's extension workflow: drag the downloaded package into a Blender window, or install it from disk through the preferences.
E Topology Smooth is released under the GNU General Public License v3.0 or later and is listed here as free. The current release is version 2.7.8, last updated on 20 February 2026. Source code and further details are published on the developer's GitHub page.
E Topology Smooth is best for blender users working on mesh topology smoothing who want G0–G4 continuity analysis and multi-algorithm curve fitting.
E Topology Smooth is completely free to download and use.
E Topology Smooth targets Blender 5.1 and newer, so you'll want a build from that release line or later. The download packages specify a minimum Blender version of 5.1, and the current release is version 2.7.8, last updated on 20 February 2026. If you're running an earlier Blender version, update Blender before installing. For the most accurate compatibility details, check the developer's GitHub page, where the source code and release history are published alongside the add-on itself.
E Topology Smooth ships as separate downloads for several platforms: Windows x64, Windows Arm, macOS Intel, macOS Apple Silicon, and Linux. Each build is packaged as a zip sized roughly between 21 and 34 MB depending on the platform. That coverage means Intel and Apple Silicon Mac users, along with both x64 and Arm Windows users, each have a matching package. Pick the download that fits your operating system and hardware, then install it through Blender. The developer's page lists all available builds.
E Topology Smooth installs through Blender's standard extension workflow. You can drag and drop the downloaded package into a Blender window, or download the zip and install it from disk through Blender's preferences. Both methods are noted alongside the platform-specific downloads. Make sure you grab the build matching your platform first, since the Windows, macOS and Linux packages are separate. Once installed, the add-on becomes available inside Blender. Blender's own documentation covers the install-from-disk step in more detail if you need it.
E Topology Smooth is listed here as free and is released under the GNU General Public License v3.0 or later. That license governs how the add-on can be used, modified and redistributed. Because the project is entirely Python and open under the GPL, its source is available on the developer's GitHub page, where you can review the code directly. For current licensing terms and any changes, the developer's page is the authoritative source. Version 2.7.8 is the release referenced here.
