FiveM will now load your custom model the one from x64a.rpf .

Historically, editing x64a.rpf was a nightmare for FiveM server owners. Standard modding tools (like OpenIV) would often corrupt the file or fail to save it because the encryption keys were not publicly available or the archive size was locked to specific hash values. If a server owner tried to replace assets inside x64a.rpf incorrectly, it would result in an instant game crash or a "corrupt game data" error on the client side.

Players would spend hours downloading a massive "Graphics Mod," only to find they couldn't join their favorite Roleplay (RP) server because the server's anti-cheat or FiveM’s own integrity check saw the modified file as a potential exploit. This gave birth to the "Citizen" folder method , where modders learned to load custom assets touching the sacred x64a.rpf. 4. The Legacy: A Modder’s Rite of Passage
