@ -3077,6 +3077,15 @@ This is basically a reference to a C++ `ServerActiveObject`
* `"skybox"`: Uses 6 textures, `bgcolor` used
* `"plain"`: Uses 0 textures, `bgcolor` used
* `get_sky()`: returns bgcolor, type and a table with the textures
* `set_clouds(parameters)`: set cloud parameters
* `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`)
* `speed`: 2D cloud speed + direction in nodes per second (default `{x=0, y=-2}`)
* `get_clouds()`: returns a table with the current cloud parameters as in `set_clouds`
* `override_day_night_ratio(ratio or nil)`
* `0`...`1`: Overrides day-night ratio, controlling sunlight to a specific amount
* `nil`: Disables override, defaulting to sunlight based on day-night cycle
