I am wanting to start small, before I jump into importing models and extensively learning jbeam. I have a fair amount of experience with Maya, Adobe CC, UE4 if that's going to help at all. I was wondering if there is a fairly simple way to take a fully functional body from a vehicle/mod, and place it onto another vehicle/mod chassis? ex: pessima body onto a d-series frame I am looking into the wikis, but not wanting to completely dive in that deep, yet. This wouldn't in any way be shared, just for my son and I, and I would check with the mod owners beforehand if possible. Likely will mainly be vanilla vehicles though. My end goal is to be able to either import and edit, or design my first love,my severely-abused, economically-lifted, off-roading, through-watering, especially-surprising, go-anywhere 2003 Subaru Outback Wagon.
I can't really help you much as I have no idea about jbeam etc. but this tutorial should push you forward a lot https://beamng.com/threads/tutorial-viewing-your-mesh-on-an-existing-vehicles-jbeam.41130/
