QuadLab Mesh Cleaner Workflow in Blender (YouTube)

Quick Start Workflow

1. Run Analyze Mesh to detect issues
2. Use Basic CleanUp to remove loose geometry and artifacts
3. Use Inspect to review detected problem areas
4. Apply Trim Mesh to remove unwanted regions
5. Use Repair Holes to close mesh gaps

Workflow Overview

QuadLab Mesh Cleaner follows a structured cleanup pipeline designed for working with scanned and irregular geometry.

Analyze Mesh

Detects common mesh issues before cleanup:

• Loose geometry and detached fragments
• Small islands and floating elements
• Open borders and hole candidates
• Non-manifold edges and problematic topology
• Degenerate and near-zero area faces
• Self-intersections and overlapping geometry

Diagnostics are visualized directly in the viewport, allowing problem areas to be reviewed before cleanup.

Basic CleanUp

Performs an initial cleanup pass:

• Removes loose geometry, fragments, and small islands
• Runs merge-by-distance cleanup to weld close vertices
• Dissolves degenerate / near-zero geometry
• Recalculates normals
• Applies limited cleanup for selected non-manifold cases

This step prepares the mesh for further processing but is not intended as a complete solver.

Inspect

Provides tools for reviewing detected issues:

• Select and isolate problem areas
• Frame specific diagnostics in the viewport
• Quickly navigate between detected issues

Trim Mesh

Allows unwanted regions of the mesh to be removed:

• Region-based trimming with visual preview
• Keeps selected areas while removing surrounding geometry
• Designed for isolating useful parts of scanned meshes

Repair Holes

Fills and reconstructs open mesh regions:

• Supports both small and large hole filling
• Includes Standard and Smart modes
• Smart mode adapts to surface curvature
• Optional surface-following behavior
• Topology-safety rollback if repair breaks topology

Notes

• The extension is designed for cleanup and preparation, not full reconstruction
• Best results are achieved as part of a manual workflow
• Complex cases may require additional manual adjustments
