Unsolved How do people port race tracks from games to beamng?

I have seen some maps where people have ported a map from a game and I want to do it with some maps from ford racing 2. (I really like the track design in that game) How do you do it?

Thanks.

 

you would open a model into blender >export it into your map folder as a .dae > open your level folder and import it > change collision mesh to visible mesh (this will make it hitable) > add your materials in the material editor, make sure your materials are also in your map's folder > save level > open documents/beamng/levels/yourmap > copy all the files there and replace the old ones in your zip. >Play!
