Check out a nice series of tutorials by Futurepoly on generating terrains for Unreal Engine 4.
Check out a nice series of tutorials by Futurepoly on generating terrains for Unreal Engine 4. The guides are quite old, but you can still learn something from them.
In this first video we build a simple terrain in World Machine. Next we use Google Maps to create tiling terrain textures based from satellite imagery. By the end of the first section we will export out a height map, slope mask and out tiling textures for use in part 2 of the series.
In this video we create a new Unreal project and import our height map from world machine to start our terrain. Next we build our materials and connect them so that we can paint the materials onto the terrain.
