So I was thinking 'woud'nt it be cool to Port cars from rigs of rods to beamng?' The only car ported is the gavril bandit by @Atomix . I would start with the gavril Omega (Hummer pick up thing) but I have 0 experience in blender, and even if I got help, I have a lot of stuff, (school, home, etc) Maybe atomix could ask me how he did it but until then ,
Unless I remember wrong, Gabester did not want his old cars being ported over, so you might be out of luck with Omega. Little search gave this: https://www.beamng.com/threads/how-to-import-cars.45041/#post-681274
If gabe does not want them ported, then there must be a good reason, i would try to get in contact with him to see why, but if its still a no then you are not allowed
its something like that he thinks his old work is of subpar quality, and he doesn't want people seeing his old work.
