GTA 6 Server Customization

Customization is what sets a GTA server apart from any other GTA server: cars, interiors, scripts, map additions. How you organize this content determines if your server feels polished or just a mess of semi-broken mods.
The three categories of customization
- Cosmetic: textures, skins and vehicle liveries. Light and low-risk.
- Structural: MLOs, new vehicles and weapons. Heavier and more complex.
- Behavioural: scripts, handling configs, economy systems. Complexity and impact are both at their highest.
The asset CDN
Custom content means custom downloads for each user. Unless you use a CDN, your game server serves those files and your network bill explodes. Solution: decouple asset hosting.
- Cloudflare R2 is very cheap and quick. $0.015/GB stored, no egress fees.
- BunnyCDN is easy to use and performs well at moderate scale.
- Some hosts include a CDN in their control panel.
Frameworks typically allow you to set an alternate resource URL so clients download resources from the CDN rather than from your game server.
Content pipeline
- Staging first. New content goes to staging, not straight to production. Learn more in our staging environment guide.
- Version everything. Git for scripts, SemVer for asset packs. See version control for mods.
- Test performance. Will the new MLO take up 50 ms of frame time? Find out before you ship to production.
- Promote with rollback. Push to production, but keep the old version ready so you can roll back instantly.
Common customization mistakes
- There is no staging. Every mod built goes straight to production. Eventually every mod that touches production breaks it.
- Too much content. 200 custom vehicles is too heavy on VRAM and confuses players.
- Poor quality control. One poorly created MLO will break immersion for your entire server.
- Lack of a change log. Players aren't aware of what's been changed. Staff can't debug.
- Copyright issues. Read our custom vehicles planning guide to learn the legal basics.

Frequently Asked Questions
Do I need an asset CDN for my GTA 6 server?
Yes, if you have more than 32 regular players. Serving custom content downloads from your game server without a CDN will cause your bandwidth bill to explode. Cloudflare R2 and BunnyCDN are inexpensive choices.
How do I add custom content to a GTA 6 server safely?
Always QA on staging, version control assets with git, profile your changes, and document everything. "We tested in production" is how you destroy servers on Friday night.
What is the performance cost of custom content?
Every custom MLO adds streaming/memory load. Every custom vehicle adds polygon/texture load on clients. Budget your VRAM and frame time, not just disk space.
