So i am making a Skoda Kagoo. I have seen pics other people made cars. Now do i have to make the doors,seats,wheels,windshield and motor and other moving parts differently. if not do i just model the car and in jbeam i will be abel to add moving parts like the door. i really need help with that since the tutorial where they make an airport tug, they did not show how to add suspension and stuff.
This goes into a decent amount of detail about the general modeling workflow of cars. https://wiki.beamng.com/Vehicle_Creation_Workflow It's not really a tutorial, but it gives some idea of things that need separated. You can also try importing the .dae file from a vanilla car and look at which parts are separate.
