Hello, I'm new in map modding and i watched a couple of tutorials about 3ds max. I want to make a short map of my country with 2-3 cities. Do i create everything in 3ds max like terrain, textures, buildings, roads, objects and then add it to GTA5? And how can i shape the map borders (coastal edges) as in real life in 3ds max? So far i've seen people make only rectangular terrains.
