* `parameters` is a table with the following optional fields:
* `density`: from `0` (no clouds) to `1` (full clouds) (default `0.4`)
- * `color`: basic cloud color, with alpha channel (default `#fff0f0e5`)
- * `ambient`: cloud color lower bound, use for a "glow at night" effect (default `#000000`)

* `height`: cloud height, i.e. y of cloud base (default per conf, usually `120`)
* `thickness`: cloud thickness in nodes (default `16`)
