Part IV

 Now the fun begins…  You can simply apply a mat the terrain… or duplicate it (ctr+d ) and use the edit tools to slightly rotate or move the duplicated terrain on any axis you choose. 

 Repeat this several times and group them all together.  You now have a seriously weird, wonderful object to play and boolean additional features with.  

 Try it and post some results to thi thread if you like.
