First of all you need to make a basic mod folder structure and get your files. A working folder structure is: name.zip/vehicles/name of vehicle Your game files should be located in: C:\Program Files (x86)\Steam\steamapps\common\BeamNG.drive\content\vehicles by default on steam Then you'll need to search for your vehicle zip in there, here's a list of the vehicles along with their filenames: https://documentation.beamng.com/vehicle_system/vehicles/index.html I'll be changing a Covet engine, so I need to look out for a zip archive with the name hatch Once I found it, I click through it's folder structure until I see all the jbeam/model/material files Then I look for an engine jbeam, it should always have a engine in it's name. In this case it's simply titled hatch_engine.jbeam I copy this file into the folder structure we just created (vehicles/hatch) in this case and rename the engine jbeam to something different than hatch_engine Then I pack my vehicles folder into a zip-compressed-folder and rename the zip to whatever. This is your mod name. Then I move it into Documents/BeamNG.drive/mods After that, I launch the game, disable all other mods and unpack the zip: Then, you can launch a map and spawn the car. Navigate to Documents/BeamNG.drive/mods/unpacked. There you should see a folder with the same name as the zip folder you created. Navigate through it until you reach your jbeam file. Open the file (I suggest using NotePad++) and you should see something along the lines of this: hatch_engine_sohc - This is our parts name, change this! 1.5L SOHC I4 Engine - This is our in-game name, change this aswell! These are the slots that define the slotname of the turbo, e.g. But we don't care about that. These are the numbers that define the torque of your engine: To get the torque of an engine, search online until you find a torque curve for it! I found that this website has a pretty big database: https://www.automobile-catalog.com/ Then, source out the numbers or try around until you get something reasonable, like I'm doing since this is a fictional engine These are the numbers that define the idlerpm and maxrpm (maximum capable) of your engine The RevLimiter is often located inside an ECU's jbeam, to find it simply search for ecu in the file If you do change the ECU, be sure to rename the same things we did with the engine! If you want to change the fuel type, change it here be aware that you may have to create another fueltank, though! Also be aware that you can change the entire sound of an engine in the soundconfig section: Everything else should be pretty self-explanatory
If it doesn't work with the "maxrpm" value in the main engine jbeam look for an ecu jbeam with a "maxrpm" value.
If you change the partname (the first one that defines the name for the game), it will be another one.
There is a wacky way just copy the engine itself and change file name and name of the engine You may also need to do the same with other parts like new ecu for the new engine
No, I'm trying to create an I4 engine for the ETK I-Series. I renamed everything I should have and changed the torque figures but it just doesn't show up in-game.
