NS Toolkit - Mesh Cleanup Pro earns its place in the Blender Extensions library by pairing topology visualization with one-click cleanup in a small, dependency-free package. The color-coded highlighting for N-gons, triangles, and quads makes it easy to see face types before running the fixes.
NS Toolkit - Mesh Cleanup Pro is a Blender add-on for optimizing and visualizing mesh topology. It runs on Blender 4.2 LTS and newer across Windows, macOS, and Linux, with no external dependencies. The add-on is powered by bmesh.ops for context-free mesh operations and ships as a lightweight package.
Its cleanup tools cover Tri-to-Quad conversion, merging vertices by distance, and normal correction, along with a reset for transform vectors. Real-time topology highlighting colors your geometry so you can spot different face types at a glance: blue for N-gons, red for triangles, and green for quads. Batch processing handles multiple objects in one pass, and cleanup runs with a single click and concise success feedback.
You'll find everything under the "NS Toolkit" tab in the 3D Viewport's N-panel, with a Ctrl+Alt+J shortcut for access. Adjust the merge distance before running, then enable topology highlighting when you want color-coded visualization. It's aimed at artists, developers, and architects working with complex or imported geometry.
NS Toolkit - Mesh Cleanup Pro is best for artists, developers, and architects working with complex or imported geometry that needs topology cleanup.
NS Toolkit - Mesh Cleanup Pro is completely free to download and use.
NS Toolkit - Mesh Cleanup Pro is built for Blender 4.2 LTS and newer, so any version from 4.2.0 up will run it. It works across Windows, macOS, and Linux and requires no external dependencies. Once enabled, its controls appear under the "NS Toolkit" tab in the 3D Viewport's N-panel. If you're on an older Blender release, you'll need to update to at least 4.2 before installing.
NS Toolkit - Mesh Cleanup Pro installs like a standard Blender extension. You can download it from Blender Extensions and drag and drop the file into Blender, or install it from disk. After that, enable it under Preferences → Add-ons by ticking "NS Toolkit: Mesh Cleanup Pro". Its tools then appear in the 3D Viewport under the N-panel's "NS Toolkit" tab. Select your mesh object or objects, adjust the merge distance if needed, and run the cleanup.
NS Toolkit - Mesh Cleanup Pro is listed as free here. On Blender Extensions it's distributed under the GNU General Public License v3.0 or later, while the developer also offers a commercial license through Gumroad. It's open source, so you can review the code on the developer's GitHub repository. The extension requires no special permissions and carries no external dependencies. For current licensing terms and distribution details, check the developer's page.
NS Toolkit - Mesh Cleanup Pro works from the "NS Toolkit" tab in the N-panel. Select one or more mesh objects, open the sidebar with N, adjust the merge distance (default 0.0001), and click Clean Mesh. The cleanup applies Tri-to-Quad conversion, vertex merging, and normal correction, with concise success feedback. You can optionally enable topology highlighting for color-coded visualization, and a Ctrl+Alt+J shortcut is available. Batch processing lets you run cleanup across multiple objects at once.
