Adding a custom livery to a FiveM car involves creating or obtaining texture files and correctly integrating them into your game files. For a basic addon livery, the core process requires a vehicle model (.yft), its texture files (.ytd, .+hi.ytd), your custom livery design in a .dds format, and a modification of the vehicle's carvariations.meta file to recognize the new livery slot. The success rate for properly configured addon liveries in a local test environment exceeds 95%, though server-side implementation depends on specific server frameworks.
The most reliable method is creating an addon vehicle, where you add a new car model with your livery pre-applied. This avoids conflicts with existing game files. First, obtain a base vehicle model that supports liveries (it must have a dedicated livery texture in its files). Using tools like OpenIV, extract the model's .yft and the relevant .ytd texture dictionaries. Design your livery in an image editor like Photoshop or GIMP, ensuring it matches the template's UV map, and export it as a .dds file (typically DXT5 format with alpha channel for transparency).
The critical technical step is editing the carvariations.meta file within your resource. Locate the liveries section for your vehicle and add a new entry defining your livery. For example, adding < Item > dlc\_name } /\ { livery\_name < /item > directs the game to your new texture. You must then replace the existing livery texture in the .ytd file with your custom .dds using OpenIV's "Replace" function. Finally, package all files (model, textures, meta files, and a correct fxmanifest.lua) into a working FiveM resource.
An alternative, simpler method for personal use is the replace method, where you directly overwrite an existing game livery. This only requires your .dds file and OpenIV. Find the target vehicle's texture dictionary in update\update.rpf\x64\dlcpacks\..., locate the specific livery file (e.g., livery_01.dds), and replace it. This method is less stable for multiplayer, as it modifies core game files and will not be visible to other players.
For server owners wanting to offer multiple liveries, implementing a livery selection system via a script is standard. This allows players to apply addon liveries in-game. The system checks player permissions or purchases, then uses the SetVehicleLivery native function to apply the chosen livery index. This requires your addon vehicle resource to be properly declared as a dependency in your script's manifest.
Common failures include incorrect .dds formats, misaligned UV maps causing stretched textures, errors in the carvariations.meta XML syntax, or missing file declarations in the fxmanifest.lua. Always test addon vehicles in a local FiveM server build before deploying to a live server. The complexity varies significantly between a simple replace for single-player and a fully scripted addon system for a public server, with development time ranging from 30 minutes to several hours based on experience.
