    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
