Multi-Pass Cleanup

Multi-pass cleanup is how you get stability: you run a sequence of small, controlled cleanups rather than one heavy pass.

What it targets

• Tiny edges and sliver faces
• Pole hotspots (high-valence vertices) that cause shading noise
• Long-thin quads that are hard to edit and deform poorly

Recommended approach

1. Start conservative (remove only obvious artifacts)
2. Check shading and silhouette
3. Increase thresholds gradually only if necessary
