To adjust planet frequency:
Find the line in `stars.vsh`: `isPlanet = (rawId > 0.95) ? 1.0 : 0.0;`
Change the value `0.95` to your desired setting. `0.95` means 5% planet frequency (100 - 95 = 5).

To change the nebula type in the night sky, you need to modify the corresponding line in `sky.fsh`:
`const int NEBULA_TYPE = 0;` The file already contains type enumerations. There will be even more in the future!
