So, I want to edit my mod without having to restart the game, so I put the extracted version in the content/vehicles folder. but when I load the mod from the vehicle selector it loads nothing and gives me this error. Please help!
Just put your mod correctly packed in mods folder, go to ingame mod manager and click "unpack" It will be here: documents/beamng.drive/mods/unpacked/"zip name"/vehicles/"vehicle name"/
You can. I'm doing it same way and I don't need to restart game. (Unless I'm changing texture or model so i need to delete cache)
Don't touch that 'content/vehicles' folder, it's a bad idea. If you want to modify a file while the game is running, then use this folder instead: 'documents/beamng.drive/vehicles' and put your files in there. It's like a mirror folder of the 'content/vehicles' folder, but without the risk of breaking your game (if something has gone wrong, you simply remove that file)
