Format Conversion Tips

Conversion Recommendations

  • Export with materials (MTL) from your 3D software
  • Consider converting to GLB/GLTF for web applications
  • Use FBX for complex scenes with animations
  • Optimize for your target use case (3D printing vs visualization)

Best Practices for OBJ

✅ Do:

  • Always include companion MTL file for materials
  • Use consistent units and scale across all models
  • Group related geometry with object names
  • Keep vertex counts reasonable for target platform
  • Use UV mapping for texture coordinates

⚠️ Watch Out For:

  • Missing materials: Include MTL file with OBJ export
  • Incorrect scale: Standardize units in source software
  • No UV mapping: Apply proper UV unwrapping before export
