You can do the same for cloud layers. For example METAR code SCT 10 translates to coverage: scattered, elevation: 10039 and FG automatically sets thickness and transition for the layer. | You can do the same for cloud layers.

Settings for maximum visual experience and rendering quality. | |||
FlightGear command options: | |||
--enable-horizon-effect | |||
--enable-clouds-3d | |||
--enable-specular-highlight (enabled by default) | |||
--enable-real-weather-fetch | |||
--shading-smooth (default) | |||
--enable-skyblend (default) | |||
--enable-textures (default) | |||
--enable-real-weather-fetch | |||
Sky Blend | |||
This rendering option enables "fog" and haze in the distance. "sky and terrain look realistic" | |||
Smooth Shading | |||
Smooths shading. | |||
Textures | |||
Terrain texturing. | |||
Volumetric (3D) Clouds | |||
This renders clouds with three-dimensional realism. | |||
Geometry/Resolution | |||
This is the resolution the FlightGear window is rendered in. The higher the resolution, the greater the detail. | |||
640x480 blocky and lacking in detail | |||
800x600 | |||
1024x768 | |||
... | |||
1600 x 1200 very fine detail | |||
and up | |||
Use anti-aliasing if you video card supports and your system can handle the extra load. | |||
Real Weather (METAR) | |||
This downloads current real world weather data into FlightGear from the nearest weather station (METAR report). The data is used to influence the environment. The cloud cover specified in the METAR report will be rendered. | |||
Time | |||
Set the current time for your location. If it's dark in San Francisco, it will be dark in the sim. | |||
Yoke and Rudder Pedals | |||
Rudder pedals add to realistic operation and make it much easier to accurately use the rudder over a twist stick. The yoke is less necessary, but can add to realism. | |||

FlightGear implements extremely accurate time of day modeling with correctly placed sun, moon, stars, and planets for the specified time and date. FlightGear can track the current computer clock time in order to correctly place the sun, moon, stars, etc. in their current and proper place relative to the earth. If it's dawn in Sydney right now, it's dawn in the sim right now when you locate yourself in virtual Sydney. The sun, moon, stars, and planets all follow their correct courses through the sky. This modeling also correctly takes into account seasonal effects so you have 24 hour days north of the arctic circle in the summer, etc. We also illuminate the correctly placed moon with the correctly placed sun to get the correct phase of the moon for the current time/date, just like in real life. | FlightGear implements extremely accurate time of day modeling with correctly placed sun, moon, stars, and planets for the specified time and date.
