Remesh

Remeshing is an automated process that rebuilds topology algorithmically, producing a clean mesh quickly but with less artistic control. Retopology is the manual or semi-manual process of drawing new edge loops over a surface, giving the artist full control over edge flow for animation and deformation.

Remeshing changes the mesh topology, which invalidates the original UV layout. To keep textures, you need to bake them from the original mesh onto the remeshed version using a tool like Blender or Marmoset Toolbag. Meshy's remesh retains the PBR texture set by rebaking automatically.

Use remeshing when speed matters and the output does not need animation-specific edge loops — for example, static props, print models, or a quick LOD. Use manual retopology for characters and deforming objects where edge flow around joints and facial features is critical.

A remesher analyzes the existing surface and builds an entirely new mesh that follows its shape, distributing polygons evenly or concentrating them where curvature is high. Voxel remeshers rebuild the surface from a volumetric grid, while quad remeshers trace new edge flow along the surface. The original topology is discarded.

A voxel remesh converts the surface into a volume grid and rebuilds a dense, uniform mesh, which is fast and guarantees watertight results but ignores edge flow. A quad remesh generates clean quad topology that follows curvature, which is better for animation but slower and more sensitive to the input surface.

Blender offers the Remesh modifier for a quick voxel-based rebuild, controlled by a voxel size that sets the output density. For quad-based results, the QuadriFlow remesh under the Object menu targets a specific face count. Both replace the original topology, so keep a backup of the source mesh.

The target depends on use: a few thousand triangles suit mobile and web, tens of thousands suit desktop games, and hundreds of thousands suit film or print. Aim for the lowest count that preserves the silhouette and key detail, since you can add surface detail back through a baked normal map.

Voxel-based remeshing usually produces watertight, manifold output because it rebuilds the surface from a solid volume, which makes it a practical way to repair messy scans or booleans. Quad remeshing depends more on the input quality and may carry over problems, so verify the result before printing or rigging.

Meshy provides one-click remeshing that outputs clean quad or triangle topology at your chosen polycount, turning raw AI geometry into a production-ready asset. The remeshed model keeps its original PBR texture set through an automatic rebake, so you do not lose surface detail.
