Scenery Detail

DETAILS

You can adjust the detail by turning graphics options on or off. To do this you can go to Options->Graphics... or pressing any of the following keys during simulation:

  • T Increase time of day (does not affect other timmings).
  • SHIFT + T Decrease time of day (does not affect other timmings).
  • V Reduce visiblie range.
  • SHIFT + V Increase visible range.
  • F9 Toggle ground base texture (not objects or landmarks).
  • F10 Toggle atmosphere.
  • F11 Toggle object texturing.
  • F12 Toggle clouds and horizon (also toggles cloud "billboard" objects).
  • SHIFT + F9 Toggle dual pass depth, the double rendering per frame in order to display heightfields more accurately.
  • SHIFT + F10 Toggle celestial objects (also toggles lighting).
  • SHIFT + F11 Toggle smoke trails.
  • SHIFT + F12 Toggle rotor prop wash effects.

For an explaination on the more complex graphics options see Setup Graphics

On the right are two images displaying different levels of detail. The first one has minimal graphics options turned on. The second image below it has all graphics options turned on. You can experiment to see how things look by toggling various graphics options on and off.

Turning on too many graphics options can slow things down and result in poor frame rates. The speed at which objects move is unaffected but their granularity (how smooth they move) will feel "jumpy".

Note that in some cases the OpenGL hardware or software that you are using can affect the quality of the graphics and/or how they appear. It is recommended that you have OpenGL hardware or software that is OpenGL version 1.2 or newer.

The graphics options can be adjusted in both free flights and missions.

Weather

WEATHER

The weather can be adjusted during simulation by pressing CTRL + W to cycle through all the available weather conditions.

Each weather condition defines the following:

  • Atmospheric Density
  • Cloud Layers
  • Sky Color
  • Cloud "BillBoard" Objects

The image on the right shows the Stormy Dense weather condition at dusk with cloud "billboard" objects. You must have the graphics option Textured Clouds turned on in order to see cloud "billboard" objects.

The weather condition will affect visiblity to some degree, but the atmospheric density is also a function of the visiblity range (which is not defined in the weather condition. To adjuts the visiblity range press V or SHIFT + V.

The weather condition can be adjusted in both free flights and missions. Missions usually define their own weather at startup. In free flight you can specify the weather at startup, for more information see Free Flight.

The weather conditions are defined in the file weather.ini you can manually edit this file to add in your own weather conditions.
