Asteroid Field script that creates local or infinite/endless asteroids fields with the amount of asteroids of your choice. Asteroids are meshes with 3 shapes with 3 levels of detail (low, medium, high.) 6 asteroid textures (Diffuse and Bump.) The Asteroid Field script will spawn asteroids with different probability for materials (so you can have a very common type of asteroid and different levels of rare (maybe precious metal) asteroids.) The script also ensure that infinite asteroid fields re-spawn asteroids that become out of range to a new location ahead of the player, but out of view. Optionally the asteroids can fade in with a temporary transparent material to make subtle appearances of asteroids.
