Tools Panel

The Tools panel (sub-panel under Quadify Ultra, collapsed by default) contains every operator that isn't part of the main Quick Remesh flow. Use it for targeted fixes, loop flow analysis, and manual remesh invocation after the main pass has run.

Presets

Eight one-click presets configure all algorithm settings for common mesh categories. Applying a preset does not run any operation — it just loads the right settings so the next Quadify run uses them.

  • Organic (Characters, Creatures) — Voxel Remesh routing, multi-pass on, conservative shape threshold. Use for sculpted characters, creatures, and any mesh with flowing surface topology.
  • Hard Surface (Mechanical, Architecture) — Hard Edge Preserving routing, high angle limit, sharp boundary protection. Use for mechanical parts, architectural models, hard-surface booleans.
  • Vehicle / Car Body — Smart routing with feature-edge preservation. Optimised for car bodies, panels, and smoothly curved hard-surface meshes.
  • Scanned Data (Photogrammetry, 3D Scans) — Voxel Remesh + Transfer routing, high decimate tolerance, noise-tolerant preprocessing. Use for dense noisy meshes from photogrammetry tools and structured-light scanners.
  • AI Generated (Meshy, Tripo, CSM, Luma) — Decimate-first pipeline, then QuadWild MEDIUM. Use for dense all-triangle output from AI mesh generators.
  • Maximum Conversion — Aggressive angle limit, accepts lower shape quality. Forces the highest possible quad count regardless of shape fidelity.
  • Quality Focus — Conservative thresholds, only near-perfect merges. Produces fewer quads but every quad is geometrically clean.
  • Balanced (Default) — General-purpose settings, good results on most mesh types without tuning.

Full Remesh

Direct access to the two remesh engines outside of the Quick Remesh flow:

  • QuadWild — runs the bundled QuadWild Bi-MDF engine at the selected resolution (Draft / Medium / Fine / Ultra). Non-blocking with a live viewport HUD. Press ESC to cancel.
  • Voxel Remesh — runs Voxel Remesh + Transfer directly, using the Voxel Detail Level from Algorithm Settings. Smart UV Project always runs after remesh to rebuild UV coordinates.

Loop Flow Intelligence

Analyses surface curvature and computes a smooth cross-field over the mesh to guide edge topology. Three modes:

  • Edge Align (follow curvature) — flips triangle diagonals to align with the computed curvature field without changing vertex positions. Fast and non-destructive. Best as a post-pass after Smart mode.
  • Curvature-Guided Remesh — runs QuadriFlow with a density derived from local curvature, concentrating faces where the surface curves most. Rebuilds geometry.
  • Analyse Loop Flow — visualises loop candidates in the viewport without making any changes. Use to inspect flow quality before committing to a remesh.

Loop Flow runs as a progress modal — Blender stays responsive and viewport redraws every 10 callbacks so you can see progress on large meshes.

Cleanup

  • Dissolve + Requadify — dissolves coplanar edges to recover true panel topology, then re-runs quadification. Best for CAD-style flat surfaces where arbitrary triangulation hides clean underlying geometry.
  • Reduce Poles — dissolves vertices with 5+ edge connections where it can be done safely without creating non-manifold geometry. Run after Smart mode for cleaner loop flow. Also available in the Results panel after any operation.
  • Fix N-gons — fans or triangulates n-gon faces, then runs a targeted quad conversion pass on the result. Use on meshes where n-gons remain after the main Quadify pass.

Poly Reduction

Reduce Poly Count — collapse-decimate followed by quad cleanup. Use when you need fewer faces and can accept some loss of fidelity. Run this before QuadWild on very dense meshes to avoid timeouts.

Feature Analysis

Visualises curvature data as a vertex colour overlay using four curvature types. Adjust the Sensitivity slider before running — higher values amplify subtle curvature differences.

  • Mean Curvature — average of principal curvatures. Best general-purpose curvature map, highlights ridges and valleys equally.
  • Gaussian Curvature — product of principal curvatures. Positive = convex dome, negative = saddle, zero = flat or cylindrical. Use to locate feature edges for loop flow planning.
  • Max Curvature (k1) — maximum principal curvature direction. Shows the direction of sharpest bending.
  • Min Curvature (k2) — minimum principal curvature direction. Shows the flattest bending direction.

Feature Analysis writes the result as a vertex colour layer. Switch Viewport Shading → Color → Vertex to view it. The overlay does not affect geometry or UVs.

Advanced / Custom Settings

Opens the full Quadify operator dialog with all algorithm settings exposed. Use when Quick Remesh dropdowns don't cover what you need — for example, specific angle limits, shape thresholds, or multi-pass configuration.
