Best Practices

1. Test all combinations - Ensure mods don't conflict
2. Use proper model names - Must exist in files
3. Document available mods - Help players customize
4. Balance performance - Don't make one option overpowered
5. Use descriptive labels - Clear modification names
6. Keep compatibility - Don't break existing vehicles
7. Version your mods - Track changes over time

Common Issues

• Mods not appearing - Model files missing
• Customization menu crashes - Invalid mod references
• Texture glitches - Wrong texture mapping
• Performance drops - Too many modifications applied
• Conflicting mods - Incompatible modifications together
