For the terrain design, representing the real world is not a priority; I want to add my fantasy elements to the scene. Since the scene reflects the natural environment in China, the town is on the edge of mountain and there is a river across the town.
UDK Landscape is compatible hardware tessellation and offers
a very different but much more powerful material editing system for terrain design.
In a nutshell, the Landscape material system is really just an extension
of the Material Editor.
To blend these two textures together, I need two nodes introduced with the Landscape system. These are TerrainLayerWeight and TerrainLayerCoords. Each texture layer needs to
have a unique name.
