I have not used any light in the scene.
The water surface is plane primitive object. Terrain and trees are editable meshes. The terrain model has been optimized and has only 13453 vertices and 26892 faces. Here are the mesh details:
Terrain: 13453 vertices and 26892 faces
Water Surface: 4 vertices and 2 faces
Palm Tree01: 45808 vertices and 46482 faces
Palm Tree02: 34502 vertices and 32882 faces
Palm Tree03: 42307 vertices and 41156 faces
Palm Tree04: 25764 vertices and 23990 faces
Palm Tree05: 34502 vertices and 32882 faces
Palm Tree06: 25764 vertices and 23990 faces.
Gradient map was used for background sky map.
Format is 3dsmax9.
