Quadify Ultra is a professional AI-powered retopology add-on for Blender 5.0. It converts triangle and n-gon meshes into clean quad topology in one click, automatically routing each mesh to the most appropriate algorithm based on its geometry type.
Unlike the Base, Premium, and Pro editions — which use deterministic, rule-based workflows — Ultra's ML engine learns from every operation and continuously improves its routing decisions. After 30+ operations on your machine, recommendations are tuned to your specific mesh types.
Quadify Ultra requires Blender 5.0 or newer. It will not run on Blender 4.x. NumPy and QuadriFlow are both included with Blender 5.0 and require no separate installation.
Download quadify_ultra.zip from your Superhive purchase. In Blender, go to Edit → Preferences → Extensions → Install from Disk, select the zip file, and enable Quadify Ultra in the extensions list. The Quadify Ultra tab will appear in the N-panel — press N in the 3D Viewport to open it.
Select a mesh object in Object Mode, then press Ctrl+Shift+Q or click the Quadify button in the panel. Ultra automatically selects the right algorithm for your mesh. The panel displays before/after statistics after each operation. Use Ctrl+Z to undo at any time — a backup is saved before every destructive operation.
Ultra includes seven retopology algorithms. The ML system routes automatically, but you can override the selection manually.
Smart — Edge flip and greedy quad matching. Works on any mesh. Never moves vertices, so geometry is preserved exactly. Best for open panels such as car doors, fenders, and clothing.
Hard Edge Preserving — Detects sharp feature edges first, then constrains quad generation within those boundaries. Best for CAD imports and boolean results where edge definition matters.
Dissolve + Requadify — Dissolves coplanar edges to recover true panel topology, then requadifies. Best for CAD-style flat surfaces with many n-gons from arbitrary triangulation.
QuadriFlow + Transfer — Field-guided remesh that generates globally consistent quad flow, then transfers UVs and vertex weights back from the original. Best for flat closed meshes and windshields.
Voxel Remesh + Transfer — Voxel field into QuadriFlow pipeline for closed organic meshes. Handles broken topology, scan noise, and complex geometry.
Full Remesh (QuadWild) — Complete retopology using the bundled QuadWild Bi-MDF engine. Replaces all geometry with clean pure-quad topology. Four resolution presets — Draft, Medium, Fine, and Ultra — control quad density and solve time. Best for organic meshes, characters, and scan data.
Instant Meshes — Field-aligned remesh via the Instant Meshes engine. Requires the Instant Meshes binary path to be set in Settings.
Open curved panels (doors, fenders) → Smart. Flat open panels (windshields, hoods) → QuadriFlow + Transfer. CAD imports with n-gons → Dissolve. Boolean results with hard edges → Hard Edge Preserving. Organic or character meshes → Voxel Remesh. Scan and photogrammetry data → Voxel Remesh. Full character or organic retopology → Full Remesh (QuadWild).
Shape keys cannot be transferred through remesh operations (QuadriFlow, Voxel Remesh). Bake shape keys to separate meshes before using these modes. Very high-poly meshes (50k+ faces) will show a time estimate warning — Smart mode is faster than remesh modes at high poly counts. Non-manifold geometry (T-junctions, internal faces) may produce unexpected results; run Mesh → Clean Up → Merge by Distance first. Mirror modifier — a warning appears if detected; for best results, process one half of the mesh with the modifier unapplied, then re-apply the mirror.
