QuadLab Mesh Cleaner earns its place in the superhive library as a dedicated cleanup and preparation step rather than a retopology tool. It leans on a visible Analyze Mesh diagnostic first, then Basic CleanUp, Trim Mesh, and Repair Holes, and it is honest about its scope: an initial pass for scanned, sculpted, and irregular meshes, not a universal solver for every non-manifold or self-intersection case.
QuadLab Mesh Cleaner is a Blender add-on focused on the cleanup and preparation of scanned objects, post-sculpt meshes, and other dirty or complex geometry. It helps inspect mesh problems, remove common artifacts, trim unwanted regions, and repair holes as part of a practical workflow before remeshing, export, or manual retopology. It is a cleanup and preparation tool, not a retopology addon.
The workflow starts with Analyze Mesh, which reveals loose geometry, fragments, holes, boundaries, non-manifold cases, degenerate faces, and other issues before any cleanup. Basic CleanUp then removes loose geometry, detached fragments, and small islands, runs merge-by-distance cleanup, dissolves degenerate geometry, recalculates normals, and handles limited cleanup for supported non-manifold cases, with optional n-gon cleanup. Inspect, Trim Mesh, and Repair Holes continue the process.
It suits scanned, sculpted, decimated, kitbashed, or otherwise irregular meshes that need a cleaner starting point. Basic CleanUp is an initial pass rather than a universal solver, some hole shapes may not repair automatically, and self-intersections may require manual correction.
Quadlab Mesh Cleaner is best for artists and technical users working with scanned, sculpted, decimated, kitbashed, or otherwise irregular meshes that need a cleaner starting point before remeshing, export, or manual retopology.
Quadlab Mesh Cleaner is completely free to download and use.
QuadLab Mesh Cleaner is listed as compatible with Blender versions 5.0 through 5.1 and ships as an add-on, marked as Blender extension compatible. It works with the Cycles and Eevee render engines and is distributed under the GPL license. If you run a different Blender build, check the developer's page to confirm the current compatibility range before installing, since supported versions can shift with new releases.
QuadLab Mesh Cleaner is a cleanup and preparation tool, not a retopology addon. Its purpose is to inspect mesh problems, remove common artifacts, trim unwanted regions, and repair holes so geometry reaches a cleaner state before remeshing, export, or manual retopology. Basic CleanUp is described as an initial cleanup pass rather than a universal solver, so it prepares meshes for those next steps instead of rebuilding topology itself. Think of it as the stage that comes before retopology work rather than the retopology itself.
QuadLab Mesh Cleaner includes a Repair Holes workflow with two options, Standard and Smart modes, plus a topology-safety rollback that steps back during repair. Before that stage, Analyze Mesh surfaces holes and boundaries alongside other issues so you can see what needs attention. Note that some hole shapes may not be repairable automatically, and self-intersections may require manual correction, so the workflow handles common cases while leaving trickier geometry to hands-on fixes. It fits into the broader analyze, clean, inspect, trim, and repair sequence.
QuadLab Mesh Cleaner offers limited cleanup support for selected non-manifold cases, and Analyze Mesh flags non-manifold geometry among the problems it reports. Support for complex non-manifold cases is limited, self-intersections may require manual correction, and very large meshes may process more slowly. Basic CleanUp is positioned as an initial cleanup pass rather than a universal solver, so it addresses common artifacts while leaving harder cases for manual work. For difficult geometry, expect to combine its passes with your own corrections.
QuadLab Mesh Cleaner is listed as free here, and it is distributed under the GPL license. Licensing terms and any pricing can change, so check the developer's page for the current details before you download or rely on it for production. The add-on is marked as Blender extension compatible and targets Blender 5.0 through 5.1, which is worth confirming on the developer's page as well if you plan to use it across different projects or Blender builds.
