Update packages are a cool things if you want temporary changes, without "hurting" the orginal content. ==> NEW thing!!! And i've noticed that all update packages and the orgininal car work side by side. So every league that uses the URD mod can make update packages without disturbing or having mismatches with the original content. It's still available. You can make an update package that only contains your league Team skins (ex: Teams_league.mas) based on the original Car. Same thing if your league wants to use custom track bilboards: Make a .mas with only the changed files. With our league we embedded the update packages in the Vmod. ==> reason: uninstall the Vmod and everything was back to the original. So no more repacking of the complete car. But 1 downfall: Your update package will download with "get missing components". But the original content doesn't. ==> For the URD cars: that doesn't matter anyway. Because the original content needs to be paid, downloaded manually If you make a complete repack: If you make a new repack of the cars but only change the version number. ==> keep the original name ! You simply install the new version and the old version will unistall itself. The old version is still there!! and will install itself if you join a server that needs it. And vica versa again. You also can do it manually in the mod manager. If you change the package name ==> repacks will be side by side but can have mismatches if you don't rename everything.
