EDIT OpenIV does not work in GTAOnline.
Yesterday, RockStar’s parent company, Take-Two, put an end to OpenIV. They said it interfered with online play with their Grand Theft Auto Online tie-in to V. Although OpenIV was made to comply with modding in Single Player, it still allows users to access the modding menu online. This is the reason it was shut down.
It is a sad day as other sites were targeted, too. But there will likely be other ways to mod games, as well as GTAV. Let’s hope they do not take the approach that Bethesda took with payed mods.
