Blender Add-on · Now on the Extensions Marketplace · Free Unreal Engine Plugin

Tri-to-quad
retopology,
done right.

Quadify converts triangulated and n-gon meshes into clean quad topology inside Blender. From a lightweight Base edition to an AI-powered Ultra engine that learns from every operation. Now with a free Unreal Engine 5 plugin for mesh conditioning and QA on import.

Use Cases

Built for real production workflows

Whether you're cleaning up scan data, optimising marketplace assets, or processing entire scenes, Quadify has an edition for the job.

🚗
Vehicle & CAD Meshes
Hard edges, boolean results, and CAD imports with n-gons. Quadify Ultra's Hard Edge Preserving and Dissolve algorithms maintain feature edges while cleaning up the surface.
95–100% quads on flat panels · 85–92% on curved surfaces
📷
Photogrammetry & Scan Data
Dense triangle meshes from photogrammetry tools and 3D scanners. Voxel Remesh + Transfer handles broken topology and scan noise while preserving UVs and weights.
90–98% quads · UV transfer preserved
🎮
Game Asset Libraries
Optimise hundreds of props with consistent poly density using Quadify Premium's Density Target — reduce by world-space surface area, not arbitrary ratios. Batch the entire library in one pass.
Consistent texel density across all assets
🏗️
Architecture & World Building
Kit-bashing, environment props, and architectural geometry imported from CAD or other DCC tools. Region-based control lets you protect silhouettes while aggressively reducing interiors.
Protected regions · LOD generation built-in
🤖
AI-Generated Geometry
Meshes from AI tools often have noisy, unstructured topology. Quadify Pro's Auto Cleanup pipeline fixes degenerate geometry, merges by distance, fills holes, and delivers clean quads ready for rigging.
Degenerate cleanup · hole filling · normal repair
🏢
Studio & Enterprise Pipelines
Quadify Pro's CLI, export presets, QA heatmaps, and HTML reports integrate into automated pipelines. Process scenes non-interactively and audit results for every asset.
CLI support · QA reports · batch CSV export

Works with Quadify Ultra
If a mesh was processed by Quadify Ultra in Blender, the sidecar JSON is read on import automatically. The QA report shows the algorithm used, quad coverage, and Ultra score alongside the Unreal score — full Blender-to-Unreal traceability.
⚡
Runs on every import
The import hook intercepts both the legacy FBX importer and Interchange. Every static mesh is conditioned, scored, and tagged before it reaches your scene — without touching anything.
⌘
Right-click from the Content Browser
Run QA, generate LODs, build collision, or condition a mesh directly from the Content Browser context menu — without opening the Quadify panel.
