At the end of these steps, or if the mod already is fine (most recently created mods) the structure should be 'mods/modname.zip/vehicles/modname/vehicle files' for vehicles or 'mods/modname.zip/levels/modname/level files' for levels. If the mod is zipped, but does not contain a vehicles folder, then unzip the mod, place the mod folder (with the vehicle/level files inside it) into a vehicle folder that you make, then send the vehicles folder to a zip like before. If the mod is not in a zip file, and is not in a vehicles folder, then follow the next steps before you zip it. If you get a mod that is not in a zip, right click the vehicles folder, and click 'Send to Compressed Archive (ZIP)', then rename the zip to the name of the mod (doesn't matter). Like said earilier, the actual mod folder with the vehicle files in it should be in a 'vehicles' folder, which is inside the zip. Before you attempt to install a mod, check that it is contained in a zip file. The structure should be 'mods/modname.zip/vehicles/modname/vehicle files' for vehicle mods or 'mods/modname.zip/levels/modname/level files' for level mods. Mods are supposed to be placed in the 'Documents/Beam.NG Drive/mods' and contained in a zip file. You generally should not put mods in here, as I don't think the in-game mod manager detects them here, and then it can be hard to distinguish between mod vehicles/levels and game vehicles/levels.

Vehicles and levels that come with game have their own folder in the game directory (not the folder in your documents). In order to understand how to install mods, you should understand how the game handles vehicle files and mods first. There is an existing thread about the mod installation change here, this thread is a tutorial for converting the old mods to the new structure. So before I get into it, this tutorial is for game versions 0.4.0.5 and later, which was released a while ago, so you should have it. I have noticed alot of confusion related to installing mods, like where you should put them, what format they should be in, what should be inside of them, and why some mods work, while other don't. Hello, this is my real official forum thread, so please give feedback.
