The scene

The scene was created as a two way street, so one bus can go up one side and the other up the other side. The scene was create with a plane at first, the plane was shaped into one half of the street then the rest was shift clicked out of the side of the street to extend it.

After one section of the street was complete i duplicated the street and moved it to the end, extending the street further.

When the street needed to turn the the bend tool was used to bend the street around the corner.

The paths and curbs where extruded out of the floor, the glass mounds extruding up and changing the vertex's to suit what was needed and extruding the walls out of the ground.

Once the Scene had been shaped the bus stop was added in, the bus stop was placed on the left side of the map, the owners of the other piece of work wanted to move in a separate direction.

Once the bus stop was placed into the scene , the bench was put into the scene. The bench is put onto the opposite side of the street to the bus stop. With the street set up the animation was ready for animating.

The sky background for the animation is assigned in the render settings for the environment, this is so the sky surrounds the entire terrain without the use of a skybox.
