I want to know how to edit official vehicles. Not just the node/beam, but also the engine properties and stuff. Previously, I used to have the Techdemo, and it showed the all the files fine. But now, when I open the vehicle files at C:\Users\attit\OneDrive\Documents\BeamNG.drive\cache.0.5.3.2\vehicles (Idk why it's in OneDrive) it just shows 2 or 3 .cdae files. I just want to know how to get to the page that looks like the image.
for steam, game files are in the locations below. i dont know about humble bundle though game files are in steamgames\steamapps\common\BeamNG.drive car/level files are in steamgames\steamapps\common\BeamNG.drive\content
If you copy a jbeam taken from the games vehicle location and put it into "...\Users\USERNAME\Documents\BeamNG.drive\mods\unpacked\CARNAME\vehicles\CARNAME" you can alter this file without the original one being affected. If you change the filename, jbeam name and the 'screen' name it will show up as a different part.
