Unity 4.x already includes a nice set of terrain modeling, texturing and mesh-population tools and assets to generate environments within Unity itself.  You can sculpt terrain, as in Max, Maya or Mudbox, or achieve displacement with height maps.  You can paint textures such as grass, sand, and cliff materials.  You can also paint in trees, flowers and foliage.  This tool looks to enhance this last part.  Take a look:  http://www.axisgamefactory.com/
