I've been lurking on the BeamNG forums, and lately I downloaded the jet-powered covet and the very heavy Gavril Pickup. I put the files in the game, but they do not appear in the menus or via the F11 world editor.... can anyone lend a hand?
how did you put them into the game? If you did it incorrectly that would be your problem. You have to open the .zip/.rar file, and put the folder inside the .zip/.rar into the vehicles folder.
