How to Fix MLO Flickering And YBN Conflicts in FiveM

November 8, 2025 · 4 min read

Many FiveM server owners encounter frustrating visual glitches, particularly MLO flickering and YBN conflicts. These issues can significantly affect the player experience, reducing immersion and creating confusion during gameplay. Understanding how to effectively address these problems can enhance the overall quality of your server and ensure a smooth experience for your players. In this guide, we will explore practical steps on how to fix MLO flickering and YBN conflicts in FiveM.

Understanding MLO Flickering and YBN Conflicts

Before diving into the solutions, it’s essential to understand what MLO flickering and YBN conflicts are. MLO, or Multi-Level Objects, are 3D models typically used for interiors and specific buildings in FiveM. On the other hand, YBN files are essential for defining collision shapes in maps. When these two systems interfere with each other, players may experience flickering visuals, where MLOs appear to glitch or disappear altogether.

Common Causes of MLO Flickering

  1. Resource Conflicts: If multiple resources try to load the same MLO, it can cause flickering.
  2. Incorrect Model Files: Corrupted or improperly formatted MLO files may not render correctly.
  3. Missing YBN Files: If the associated YBN files for an MLO are missing or incorrectly configured, it can lead to issues.
  4. Rendering Limits: Sometimes, performance settings can impact how MLOs are displayed.
  5. Outdated Scripts: If you’re using outdated scripts, they may conflict with the new MLO models.

Steps to Fix MLO Flickering

To address MLO flickering effectively, follow these detailed steps:

1. Verify Resource Integrity

  • Check the MLO file’s integrity by ensuring that the model files are complete and not missing any textures or related assets. Use a tool like OpenIV to open the files and verify.
  • Look at the fxmanifest.lua file to ensure it references all necessary files correctly. It should include lines similar to:
    files {
        'your_mlo_file.yft',
        'your_ybn_file.ybn',
    }
    

2. Remove Conflicting Resources

  • Identify and remove any duplicate MLO resources from your server’s resources folder.
  • Check your server.cfg for any redundant resource starts. Remove duplicates that may be trying to load the same MLO:
    start resource1
    start resource2     # Make sure resource names are unique
    

3. Update Rendering Settings

  • Review the client.lua settings to optimize rendering limits. Too high a setting can cause visual glitches:
    SetMaxDynamicObjects(300)  -- Adjust this according to your needs
    

How to Resolve YBN Conflicts

Resolving YBN conflicts involves ensuring that all YBN files are correctly configured and associated with their respective MLOs:

1. Recheck YBN File Associations

  • Ensure that all YBN files are present for each MLO you're using. If you’re missing a YBN file, the MLO may not load properly.
  • Update your config files accordingly, such as fxmanifest.lua, similar to the MLO verification step.

2. Adjust Collisions

  • If a YBN conflict causes games to crash or flicker, consider using a custom collision file. You can create a new YBN file using tools like Codewalker to reassign collision properties.

3. Test in Single Player Mode

  • Before deploying changes server-side, test the MLO and YBN integration in single-player mode. This allows you to identify issues without affecting other players.

Best Practices for MLO and YBN Management

To ensure long-term stability and reduce the chances of flickering and conflicts, consider the following best practices:

  • Keep Scripts Updated: Regularly check for updates on scripts and MLOs you use. This ensures compatibility and optimizations are applied.
  • Organize Resource Files: Maintain a clear structure for your resource folder to easily identify and manage MLO and YBN files.
  • Back Up Your Server: Before making significant changes, always back up your server files. It protects you from potential issues with new installations.
  • Monitor Performance: Use performance monitoring tools to identify bottlenecks and optimize MLO loading.

Frequently Asked Questions

Q1: Why does my MLO flicker only when multiple players are around?
A: This is likely due to resource limits being reached. Review your server’s settings and adjust your rendering limits accordingly.

Q2: What tools can help with fixing MLO files?
A: Tools like OpenIV and Codewalker are excellent for managing and editing MLO and YBN files.

Q3: Can I prevent YBN conflicts by naming files uniquely?
A: Yes, ensuring unique names can reduce conflicts, but you must also verify that all related resources are correctly configured.

Q4: How can I test MLO changes without affecting my live server?
A: Use a local server setup or single-player mode to test MLO integrations before going live.

Q5: Is there a specific FiveM framework that handles MLOs better?
A: Both ESX and QBCore offer robust support for MLOs, but the choice depends on your server’s needs and your familiarity with the framework.

By following this guide, you should have a clearer understanding of how to fix MLO flickering and YBN conflicts effectively in FiveM.
