RETOPOLOGY

Retopology

Rebuild a high-poly model as a lighter triangle or quad mesh.

Last updated: 2026-08-20

Retopology reduces model complexity and reorganizes the mesh for games, web 3D, AR/VR, mobile presentation, rigging or further editing.

Retopology workspace
Load a source model, then choose the model version, polygon level and topology type.

Supported inputs

Upload a GLB or OBJ up to 60 MB, or choose an existing model from account assets.

Polygon level

Low

Fewest polygons for distant views, mobile and many instances.

Medium

A balance of silhouette and performance; a good first attempt.

High

Preserves more shape detail for close views and editing.

Topology type

TypeBest forNotes
TrianglesGame engines, real-time rendering and web 3DStable rendering, less convenient for loop editing
QuadsSculpting, rigging, deformation and modelingEasier to edit; inspect joints and thin surfaces

Procedure

  1. Choose a source

    Upload GLB/OBJ or select an asset.

  2. Choose a processing model

    Use the latest Mesh3D V1.3 in most cases.

  3. Set polygon level

    Start with Medium, then compare the silhouette.

  4. Choose topology

    Use triangles for real-time rendering or try quads for editing.

  5. Generate and inspect

    Check contours, holes, thin surfaces and joints.

NEXTUV unwrapping

Create 2D coordinates for the optimized model.
