Terrain sculpting

I've been making various models in 3DS Max to create test zones, this way we can see examples of the way the game will look and be able to pick which direction to carry on with. Before I show these off though I need to be proficient in making the landscape. To make the terrain I'm using a different software which should speed up the process. I got to get the knack for it first so for the next few days I'll be making loads of maps.
