Create the terrain using world machine. There’s a lot of tutorials on youtube showing how to do this. Import it on UE4. Create terrain materials.
-
For trees, you can use speedtree, or buy game ready models.
-
For buildings, you usually model them from scratch. You can use many tools, even free ones like Blender.
-
If this is your first game and you are just starting, avoid complex projects like this. A game is much, MUCH more than just a terrain with objects. It would take months, and probably years, for an experienced person to create a good quality 300km map populated with vegetation, rocks and other props alone.
