📘 Mesh CleanUp Tool

Mesh CleanUp Tool is a powerful Blender add-on designed to simplify and accelerate your mesh cleanup workflow. Whether you're preparing models for game engines, 3D printing, or asset delivery, this tool provides one-click cleanup solutions and in-depth mesh analysis directly in Edit Mode.

🧭 Getting Started

1. Install the Add-on:

   • Go to Edit > Preferences > Add-ons

   • Click Install... and select the .zip 

     Enable the checkbox next to Mesh CleanUp Tool

2. Access the Tool:

   • Enter Edit Mode (Tab key)

   • Press Shift + M or search for "Advanced Mesh Cleanup" in the F3 menu

🧼 Cleanup Options

🔹 Remove Doubles

• Merges overlapping or duplicate vertices based on a set merge distance.

• Adjustable Merge Distance slider for precision control.

🔹 Dissolve Degenerate

• Removes tiny, zero-area faces and unnecessary edges automatically.

🔹 Delete Loose Geometry

• Allows deletion of:

  • Loose vertices (not connected to any edge)

  • Loose edges (not part of any face)

  • Isolated faces

🔹 Dissolve Redundant Geometry

• Automatically dissolves:

  • Vertices connected to only two edges that lie in a straight line.

  • Edges that don’t affect mesh shape, based on a customizable angle threshold.

🔹 Recalculate Normals

• Rebuilds face normals for consistent shading.

• Optional flip normals toggle for correcting reversed normals.

🔍 Analysis & Selection

After cleanup, the tool can automatically select problem areas for inspection:

• Non-Manifold Edges

• Non-Planar Faces (with threshold control)

• Triangles (Tris)

• N-Gons (faces with 5+ edges)

You can also enable "View Selected" to focus the viewport on the detected areas.

⚙️ Settings Summary

🎯 Use Cases

• Game asset preparation

• Fixing imports from CAD or other DCCs

• Reducing geometry for performance

• 3D print prep & error checking

• Technical and hard surface modeling

💡 Tips & Best Practices

• Combine this tool with Auto Merge and Snap to Vertex for retopology workflows.

• Use View Selected to quickly inspect large, complex meshes.

• Fine-tune angle threshold to control how aggressively edges and verts are dissolved.

❓ Troubleshooting

Q: The tool doesn’t appear when I press Shift+M?
A: Make sure you are in Edit Mode, and that your selected object is a mesh.

Q: Nothing seems to happen after clicking "Execute Cleanup"?
A: There may be nothing to clean. Try enabling selection of problem areas to confirm.

🛠️ Version Compatibility
