Basically, you have something like this: (Perlin, 10, 200).
- Perlin is the type of terrain you have for your planet. Choose between Perlin, Craters, Mars, Phobos, Io... (Am I forgetting something?)
- 10 is, how many times you want that pattern repeated along the planet. Low numbers will make plains. High numbers will make chaotic terrains.
- 200 is the height in meters you want your terrain to reach...
