other question…
How can i run the island demo inside unity3d? i can’t found it?

you can download Terrain Assets here for free: Terrain Assets | 3D Vegetation | Unity Asset Store

and if i remember correctly, island demo doesn’t come with Unity 3.3
you can download it here though: http://unity3d.com/support/resources/example-projects/islanddemo

But How Can I Import this Terrain Assets?

I need to learn how to add comments and not post answers

If you are in version 4+, you can download them from the Asset store by searching for “terrain assets”. This will give you the items to import directly into your project.
