The terrain available to create your tracks is a grid of 900 squares (30x30). Track elements can occupy 1, 2 (2x1) or 4 (2x2) squares. There are 149 track and stunt elements, and 28 elements of scenery (windmills, trees, ...) available by the game (not counting the water and hill elements). If you use external track/terrain editors, you may also add one more scenery element : a car, same as the one you use. Track Blaster utility allow you to do it for example.
