Why we like it

FUM - Fix Your Mesh earns its place in the superhive library for folding a set of common topology checks into a single Export Preflight workflow with clear PASS, WARNING, and FAIL feedback.

What is Fum - Fix Your Mesh?

FUM - Fix Your Mesh is a lightweight Blender addon focused on mesh validation and export preflight workflows. It helps artists quickly identify common topology issues before exporting assets into production pipelines.

The addon detects non-manifold edges, flipped normals, N-gons, duplicate vertices, and isolated vertices. Open the FUM panel inside Blender and run Export Preflight to evaluate the mesh, which returns a clear PASS, WARNING or FAIL result. Running individual checks highlights problematic geometry inside the viewport.

The addon is built around a simple export validation workflow designed for speed, clarity, and usability, rather than functioning as just a collection of separate mesh checks. It centers on quickly evaluating whether a mesh is production-ready before export. Documentation is available. FUM works with Blender 4.0 and later and is released under the GPL-3.0 license.

Who is Fum - Fix Your Mesh best for?

Fum - Fix Your Mesh is best for blender artists who want to validate mesh topology and run an export preflight before sending assets into production pipelines.

Frequently asked questions

Does FUM - Fix Your Mesh work with Blender 4.0?

FUM - Fix Your Mesh lists compatibility with Blender 4.0 and later, with a supported range spanning Blender 4.0 through 5.1. If you are running a version inside that range, the addon is stated to be compatible. For the most current compatibility details or any changes tied to newer Blender releases, check the developer's page before installing so you can confirm your specific version is covered and avoid surprises during setup.

What geometry issues does FUM - Fix Your Mesh check for?

FUM - Fix Your Mesh checks for several common topology issues: non-manifold edges, flipped normals, N-gons, duplicate vertices, and isolated vertices. These are the mesh problems the addon is built to identify before assets are exported into production pipelines. Running individual checks highlights the problematic geometry directly inside the Blender viewport, so the flagged areas are visible in the scene. The PASS, WARNING, and FAIL system then summarizes the outcome of those checks.

How does the Export Preflight workflow in FUM work?

FUM - Fix Your Mesh is built around an Export Preflight workflow. You open the FUM panel inside Blender, run Export Preflight, and review the results, which are reported through a clear PASS, WARNING, or FAIL system. From there, you can run individual checks to highlight the specific problematic geometry inside the viewport. The addon is designed around this single export validation workflow rather than as a loose set of separate mesh checks, with a focus on speed, clarity, and usability.

Is FUM - Fix Your Mesh free to use?

FUM - Fix Your Mesh is listed as free in this catalog. Licensing and pricing can change over time, so if you want to confirm the current terms before downloading, the developer's page is the best place to check. The addon itself is released under the GPL-3.0 license, which governs how it can be used, modified, and shared once you have it. Check the developer's page for the latest download and licensing information.
