Changes in the 3D Environment

At first, my plan is to create the 3d city environment using Autodesk 3ds Max 2009 and then import it to Unity software for animation. I tried to import some of my 3d model to Unity and find it hard and complicated as I need to import all the materials texture that I already applied to my 3d model in 3ds Max separately. Looking at some of the tools provided in the Unity software, I have decided to make a slight change to my 3d environment, basically from a city environment to an island.
