3D Model Quality Control: Pre-Publication Checklist

Why Quality Control Matters

A faulty or unoptimized 3D model can reduce your product page performance and negatively impact customer experience. A systematic check process before publishing minimizes these risks.

Geometry Checks

• Polygon count: Between 10K-50K for web? Under 20K for mobile targets?
• Normal directions: Are all surface normals facing outward? Inverted normals appear as black spots.
• Manifold geometry: Is the mesh closed and watertight? Any open edges or interior faces?
• Scale: Is the model at real-world dimensions? 1 unit should equal 1 meter (GLTF standard).
• Origin point: Is the model center point in a logical position? Usually at the base center.

Material Checks

• PBR compliance: Are materials in GLTF PBR metallic-roughness workflow?
• Texture resolution: Unnecessarily high? 2048x2048 is sufficient for most products.
• Texture format: JPEG (photo-type) and PNG (alpha needed) used correctly?
• UV overlap: Any overlapping in the UV map? Overlaps create texture errors.

Visual Checks

1. Rotate the model on a white background - check every angle
2. Test under different lighting conditions (bright, dark, neutral)
3. Zoom in to inspect details
4. Compare with the real product photo - are colors and proportions correct?

Performance Checks

• File size: Is the GLB file under 5 MB? Ideally between 1-3 MB.
• Load time: Does it load in acceptable time on a 3G connection?
• Frame rate: Is it smooth during rotation? Target 30+ FPS.

Conclusion

By applying this checklist to every model, you can establish a consistent quality standard. After the first few models, the process becomes automatic and faster.
