FUM — Fix Your Mesh

FUM is a lightweight Blender addon focused on mesh validation and export preflight workflows.

It helps artists quickly identify common topology issues before exporting assets into production pipelines.

Main Features

• Non-manifold edge detection
• Flipped normal detection
• N-gon detection
• Duplicate vertex detection
• Isolated vertex detection
• One-click Export Preflight workflow
• Clear PASS / WARNING / FAIL result system
• Viewport issue highlighting

Designed for Practical Workflow

FUM is not just a collection of mesh checks.

The addon is designed around a simple export validation workflow that allows artists to quickly evaluate whether a mesh is production-ready before export.

The goal is speed, clarity, and usability.

How It Works

1. Open the FUM panel inside Blender
2. Run Export Preflight
3. Review PASS / WARNING / FAIL results
4. Run individual checks to highlight problematic geometry inside the viewport

Compatibility

Blender 4.0+
