How can I install vehicle.meta files etc. I only know add ons.
@kaedenizaac It's at mods\update\update.rpf\common\data\levels\gta5 if you mean to modifying that vehicles.meta .
Need to drag and drop it to your pc, and edit the lines where it's necessary. Then save and drag and drop back into openiv.
Use notepad++ to make the editing a lot easier
