How to Convert a Single-Player Car Mod to a FiveM Add-On

To convert a single-player GTA V car mod to a FiveM add-on, give the model a unique name, put its .yft and .ytd files in a stream folder, edit the meta files so every reference uses the new name, and write an fxmanifest.lua that declares them. Then ensure the resource and test it. A huge amount of GTA V car content was made for single-player as replace mods; converting one to an add-on is doable, though quality varies wildly by source model.

Why is conversion needed?

Replace mods overwrite a base car and can't coexist with others. Add-ons spawn under their own name and stack freely — the right format for any server, as covered in add-on vs replace.

Is there a FiveM car converter?

Yes. If you'd rather not do it by hand, our partner GTA5 Mods Convertor automates the replace-to-add-on process and saves you the meta-editing rabbit hole. A converter changes the format, not the model: a heavy or badly built source car stays heavy. If you want a car that needs no conversion at all, our add-on cars are already FiveM resources.

1. Give it a unique model name

The core of conversion is renaming the model and its files to something unique, then building the meta around that name so it no longer clobbers a base vehicle.

2. Build the resource structure

Create a proper stream folder for the model/textures and a data folder for the meta files, then write an fxmanifest.lua declaring them — the same anatomy from our custom car guide.

3. Fix the meta references

Update vehicles.meta, carvariations.meta, carcols.meta and handling.meta so every reference points to your new model name. Mismatches here cause invisible or untextured cars.

4. Test thoroughly

Converted models are where collision, LOD and texture bugs hide. Run through our vehicle error checklist before trusting it on a live server.

Can you convert a FiveM car to single player?

Yes, the conversion works in the other direction too, because the model and texture files are the same in both. A FiveM resource loads them from a stream folder through its fxmanifest.lua; single-player loads them from a DLC pack. You build a dlc.rpf in OpenIV that holds the same .yft and .ytd files and meta files, described by a content.xml and setup2.xml, and add the pack to dlclist.xml. Two limits: a resource protected by Cfx.re's asset escrow is encrypted and cannot be repacked, and the licence you bought the car under decides whether you may use it outside FiveM.

Is converting worth it, or should you buy an add-on?

Conversion is time-consuming and a poorly made source model will never perform well, no matter how clean your conversion is. When time matters, professionally built add-on cars drop in optimized and ready — no conversion required. Car packs cover a whole category in one download, and the free cars let you check the install on your server first.
