If atmosphere visuals are rendered, Earthview interacts with the weather system in that the visibility used by Earthview and by the weather system will be the same. In the case of [[A local weather system | Advanced Weather]] (AW) this is an issue because both systems try to adjust atmosphere visuals. For this reason, AW needs to be ended before Earthview is started. There is no general option to do this automatically, but an automatic transition from default FG rendering and weather to Earthview is easily coded spacecraft side and implemented for the Space Shuttle. | If atmosphere visuals are rendered, Earthview interacts with the weather system in that the visibility used by Earthview and by the weather system will be the same.

All textures are taken from the [http://visibleearth.nasa.gov/ NASA Visible Earth project] - at the highest resolution level, Earth can be rendered at 32768x65536 pixel (about 500 x 500 m per pixel) and clouds with half of that. Currently | All textures are taken from the [http://visibleearth.nasa.gov/ NASA Visible Earth project] - at the highest resolution level, Earth can be rendered at 32768x65536 pixel (about 500 x 500 m per pixel) and clouds with half of that. Currently, due to size concern, all the textures distributed in FGData are of low resolution (2048p x 2048p per tile) and do not incorporate the alpha channel encoding the height. Parallax mapping for ground textures is therefore disabled. It is however possible to obtain the textures from the NASA website, process them and straightforwardly use them as a replacement. More detailed instructions to do so are given below in the section "Customization". | ||
