popular mods like: the ibishu hopper, are they upgrades for engines or the original mod imported into the game? because i have it in the game but i havent installed the mod, i would appreciate an answer to my questions, because i really dont know, examples: the ramplow, and the ibishu hopper
The "Hopper" is a vehicle and the "ramplow" is a part (front bumper) for the Semi (T-series) vehicle. Both of these things are official content and are included in the game.
https://www.beamng.com/forums/content-created-by-beamng.10/ Notice 'Content Created by BeamNG'. All of those are content that we are working on, and are going to be part of the actual game's content.
They weren't originally in the game, but were added recently as part of an update. BeamNG is still in development, so you'll see frequent updates where the devs fix or enhance certain features and even add more content like the Hopper and Ramplow.
The AR126B T-Series Addon was released near March 13th 2015. @Nadeox1 Do you remember when the Plow was added to the official game?
I meant What Date, not version, but AR126B's pack was testing in about 0.6 or close to that. But what date was the stuff added?
