Hello, today I will show you the detailed and basic process of swapping another engine into a car in BeamNG.drive, and a basic blender tutorial. NOTE: This does take quite a background of blender and jbeam knowledge, if you know how to rename and move stuff, and copy paste in notepad and blender, your good to go. Ok, onto the tutorial: STEP 1: Get the vehicle you want to put another engine in, I'm going to use @Stoat Muldoon 's 1970 Dodge Coronet, and I'm going to be swapping in a 6.4L HEMI Engine. STEP 2: Get the .dae file of the vehicle you want to swap another engine in, don't know how? It's simple! Open the .zip file (if your doing official vehicles, open Program Files (x86)/Steam/steamapps/common/BeamNG.drive. You should be to a page something like this: STEP 3: Open up the folder "content" then "vehicles" and you should see a lot of zipped files with the vehicles name on them. NOTE: Some vehicles are named weird, here's the codes to what each .zip file name actually links to in the game: Code: sbr.zip- SBR4 super.zip= Bolide legran.zip= LeGran barstow.zip= Barstow etkc.zip= ETK-K etk800.zip= ETK800 etki.zip=ETK-I midsize.zip= New Pessima fullsize.zip Grand Marshal pickup.zip=D-Series roamer.zip= Roamer semi.zip= T-Series sunburst.zip= Sunburst van.zip= H-Series moonhawk.zip= Moonhawk burnside.zip= Burnside Special pessima.zip= old Pessima pigeon.zip- Pigeon hatch.zip= 200BX That should be a list of every single vehicle in BeamNG As a .ZIP, That should come in handy if your using official vehicles. STEP 4: Once you have found the folder the vehicle you want to put another engine in, copy and paste that folder to your desktop, so it's easier to assess. (DO NOT DRAG THE .ZIP OF YOUR VEHICLE TO YOUR DESKTOP, COPY AND PASTE IT. IF YOU DRAG THE FOLDER THAT VEHICLE WILL BE MISSING FROM THE VEHICLE SELECTOR) your desktop should look like this: STEP 5: Open up the vehicle .zip and look for a file named .dae (if your using the sbr, it will be named sbr.dae, if your using the roamer, it will be named roamer.dae, get it?) it should look like this: STEP 6: Extract The folder to your desktop, afterward, it should look like this: STEP 7: keep the .zip somewhere safe just in case if you mess up, you have a backup, so don't delete it. STEP 8: Open the non compressed folder, look for the .dae again, and drag it to your desktop. Then open blender. STEP 9: This is when your going to need some basic blender knowledge, import your .dae into blender, like this: STEP 10: Delete everything but the engine bay. Here's how to do it with pictures: Do that for all engine parts including intakes, headers, etc. then hit A, then delete, like you did the square, final output should be something like this: STEP 11: get the engine you want to swap into the vehicle. redo steps 4, 5, 6,7 ,8, and 9. STEP 12: once you have found the .dae of the car with the engine you want to swap, import it like you did the first vehicle, go back to step 8 and 9 for that. STEP 13: Once you have imported the car you want to engine swap, it should look like this, very messy, but don't panic! Once you have imported your vehicle into blender, delete everything but the intakes and engine. go back to step 10 if you can't remember. STEP 14: It should look like this now: STEP 15: Drag over your imported engine over the original engine, then delete the original engine oce the imported engine is replaced. should look like that. click all of those to where there highlighted. delete the original engine. should look like this now. STEP 16: rename the engine, by right clicking it in the mesh selector and replace "fullsize" with "coronet" like this with pictures: same applies to any other vehicle, but if your using the legran and covet, replace "legran" with "covet", applies to any other vehicle. STEP 17: export the .dae, but first you must apply rotation location and scale to the engine, hit CTRL+A And then hit "rotation" then do this in the pictures: hit those two unchecked boxes. STEP 18: Export the .dae to your desktop, so you have the file ready to use. to export, click on "file" on top top left and corner, then "Export" Then Collada.DAE The click "desktop" on "System Bookmarks" then in the top right hand corner click "export". A file named untitled.dae will come up on your desktop, close you blender it's not needed anymore. STEP 19: Open up the file you unzipped a few minutes ago, so then you should have something open like this: Look for "(vehicle name)_engine.jbeam" or type it in into the search bar, whatever you prefer. So you should have this: STEP 20: open the .jbeam in notepad++, (if you don't have notepad++, download it here) STEP 21: When you open it, lots of numbers and letters will come up, dont panic! It's going to be easy, just highlight the entire first engine jbeam, like this: All the way down to this: STEP 22: right after the ], In the code under the engine, hit enter twice, then hit CTRL+V And it will paste. Go to the top of your pasted code and edit the top so it works. STEP 23: Rename the engine. This is the most important part. do as is in these pictures: save the file, then exit. STEP 24: Make a new folder inside the unzipped mod folder. name it *vehiclename*_engine like this: STEP 25: Remember that .dae we exported just a few minutes ago? We are going to need that. Rename the "untitled" to 6.4, or whatever you named the engine in blender. Here's an example: STEP 26: Your going to need textures so it doesn't appear as "no material" in BeamNG. If you do not know the engine's texture file, reopen it in blender and check. (by clicking the plus until you get to the circles below the black and grey triangle) STEP 27: open the materials.cs. A bunch of letters will come up, don't freak out, this is simple. Just reopen the folder that you got the model from (the engine imported folder, for me, it's the dodge charger by @Dean Wang ) and type in "*vehiclename_engine" in the materials.cs by pressing CTRL+F you will find this: copy and paste it into the materials.cs into the vehicle you engine swapped (in my case, the dodge coronet). then save it. STEP 28: you should be done, zip the folder and drag it into BeamNG. Then you should be done! 28 steps later, you have a new engine inside another vehicle! Have any questions reply And someone will answer! P.S: You will have to select the engine in the vehicle customization for it to come up this took 4 hours to type and do, so i hope this helped you.
