In this thread, I will show the process of creating the famous Ebisu Circuit for BeamNG. I decided to start with a small School Course. When modeling the 3d model of the track, I used a lot of photos and photo geometry of the terrain for a high accuracy of the track. Attached are screenshots of the work done. P.S I do not speak English well, so there may be errors in my text.
After processing the terrain, the track looks like this. This is not the final version, much more will change
