QuadMend

A Blender add-on that fills holes, n-gons and boolean cuts with clean all-quad patches. It picks the pattern for you, keeps your UVs and never writes folded faces.

A slab with four boolean holes: 48 n-gons before, clean quad rings around each hole after QuadMend

What it solves

The gap

Deleting faces or running a boolean leaves holes and n-gons. Grid Fill gives up on uneven or concave borders, or returns a skewed grid that shades badly and is hard to keep editing.

What it is

QuadMend fills the hole or rebuilds the selected faces with an all-quad patch. It chooses the corners and pattern from the border, splits concave borders, keeps UVs and checks every patch for folded faces before writing it.

How you use it

Select the border of a hole in Edit Mode and run Quad Fill from the right-click menu or the QuadMend sidebar tab.

A topology repair tool, not a remesher: it keeps your existing mesh and rebuilds only the holes, n-gons or faces you choose.

Who it is for

Use it when

  • Cleaning up the n-gons an exact boolean leaves on a hard-surface model.
  • Closing holes in organic meshes without a flat dent.
  • Joining two open edge chains with different edge counts.

Built for

  • Blender modellers working on hard-surface and organic meshes.
  • Game and asset artists who need clean quad topology before export.

What it does

Fills holes with clean quads

Select the border of a hole, or the faces you want to redo, and get an all-quad patch. The corners and the pattern are picked from the shape of the border; concave borders are split first.

Cleans up after a boolean

N-Gons to Quads groups the flat n-gons around each hole and rebuilds them as rings, balancing odd pairs so they need no triangles (Full).

Uneven sides, still quads

Nine edges facing three get transition rows instead of a skewed grid. Quad Bridge joins two open chains with different counts (Full).

Never writes folded faces

Every patch is checked before it touches your mesh. When no safe layout exists, the region is left as it was and QuadMend tells you why.

Keeps your data

UVs are interpolated from the border, material slots and smooth shading are kept, and existing edges are never doubled.

Fast on real meshes

In the repository benchmarks a 256-edge hole fills in about 0.2 s, and a hole in a 520,000-face mesh in under a second.

Questions

No. It keeps your existing topology and rebuilds only the holes, n-gons or faces you choose. Use a remesher for whole-mesh retopology.

A region bounded by an odd number of edges cannot be filled with quads only. QuadMend uses exactly one triangle and places it at a sharp corner or on the longest edge.

Lite has Quad Fill with automatic patterns, concave splitting, Relax and kept UVs. Full adds Smooth, transitions, Ring Fill, N-Gons to Quads, Fill All Holes, Quad Bridge, batch cleanup and 12 months of updates and support. Only one edition can be enabled at a time.

Blender 4.2 or newer. It is tested on Blender 4.2 LTS, 4.5 LTS and 5.2 LTS.
