The Advanced Sky Editor contains detailed controls for modifying environmental effects. It is where you  make visual changes to sky and atmosphere presets, also known as "keyframes" (see [[Day Cycle Editor]] for more about keyframes). It contains three tabs, each with a number of sliders for manipulating the sky's appearance. You may also save and load sky settings when you find a view you like.
 
==Opening the Advanced Sky Editor==
 
The Advanced Sky Editor is located in the Environment Editor:
 
# Go to '''World > Environment Settings > Environment Editor[[Image:kbsd_Kb_sky_menu_open_2.jpg]]'''
# In the Environment Editor, click the '''Advanced Sky''' button[[Image:kbsd_Kb_sky_menu_basic_2.jpg]]
 
==Overview of Advanced Sky Editor Settings==
 
===The Atmosphere Tab===
 
[[Image:kbsd_Kb_sky_atmosphere_menu_2.jpg]]
 
This tab controls elements of the atmosphere itself:
 
'''Blue Horizon:''' Use the Red/Green/Blue (RGB) sliders to adjust the color of the sky. You can use the Intensity (I) slider to move all three RGB sliders in unison. In meteorological terms, this setting affects "atmospheric scattering", which is the scientific answer to the age-old question, "[http://www.sciencemadesimple.com/sky_blue.html Why is the sky blue]?"
 
'''Blue Density:''' Blue Density affects the overall color saturation of your sky. If you move the Intensity (I) slider to the right, your colors will become brighter and more vibrant. If you move it all the way to the left, your colors will become duller, eventually fading to black and white. If you'd like to fine-tune your sky's color balance, you can control individual elements of saturation by using the Red/Green/Blue (RGB) sliders.
 
{{KBhint| Blue Horizon and Blue Density are particularly closely related. Imagine Blue Horizon as the base color for the sky, and Blue Density as the sky's color intensity and color balance effects. Try turning Haze Density to zero and playing with these settings for yourself to get a better feel for how they interact with each other.}}
 
'''Haze Horizon:''' This setting affects the height of haze on the horizon. At higher settings, the haze will reach up into the sky and obscure the actual horizon. Haze on the horizon can help to accentuate the sun, and create a dusty, smoggy, or humid effect. This setting will not work if Haze Density is set to zero.
 
'''Haze Density:''' Haze density affects the amount of haze you can see in the atmosphere. At lower settings, this can make for some great outdoor views in dusty or tropical environments, and at higher levels it can create a thick, vision-obscuring fog. If you set Haze Density to zero, the Haze Horizon setting will have no effect.
 
'''Density Multiplier:''' The Density Multiplier can be used to affect the overall atmospheric density. At lower settings, it creates a feeling of "thin air", and at higher settings, it creates a very heavy, smoggy effect.
 
'''Distance Multiplier:''' This setting affects your perceived distance within the atmosphere. To make everything look hazy and distant, move the slider to the right. If you want to completely remove the Sky Settings' effects from terrain and objects, set the slider to zero.
 
'''Max Altitude:''' Adjusts the altitude calculations Second Life makes when it is computing atmospheric lighting. At later times of day, it can be useful for calculating how "deep" a sunset appears, while at noon it can be used to achieve proper brightness values.
 
===The Lighting Tab===
 
[[Image:kbsd_Kb_sky_lighting_menu_2.jpg]]
 
This tab controls the sun, ambient lighting, and the stars:
 
'''Sun/Moon Color:''' This setting affects the color of the light your sun and moon produce. Keep in mind that the color of your sunlight/moonlight will affect the color of your sky! To change Sun/Moon Color, use the Red/Green/Blue (RGB) sliders, or use the Intensity (I) slider to move all three RGB sliders at once.
 
'''Sun and Moon Position:''' The Sun and Moon Position setting affects the vertical position of the sun and moon, from sunrise (0.0) through noon (0.25), sunset (0.5), midnight (0.75) and back to sunrise (1.0). Note that this setting is different than Time of Day in the Basic Environment Editor. The Time of Day setting shifts through your WindLight keyframes (see [[Day Cycle Editor|The Day Cycle Editor]]), while the Sun and Moon Position setting only affects the physical location of the sun and moon.
 
'''East Angle:''' The East Angle affects the horizontal position of the sun/moon, and is similar to [http://en.wikipedia.org/wiki/Azimuth azimuth]. At settings of 0.0 and 1.0, the sun will rise in the East and set in the West. The settings in between define the entire circle of the horizon; at a setting of 0.5, the sun will rise in the West and set in the East, at a setting of 0.25 the sun will rise in the South and set in the North, etc.
 
'''Sun Glow:''' There are two settings under Sun Glow: '''Size''' defines the size of the sun, and '''Focus''' adjusts how much the sun blurs over the sky. At very high settings, Focus can cause the sun to completely wash out a portion of the sky with brilliant light, and at zero, it will cause the sun (but not the light it casts) to disappear from the sky.
 
'''Ambient:''' This controls the color and intensity of ambient light in the atmosphere. This is used for simulating how the light from the sun is scattered by the atmosphere and other objects once it hits the Earth. You can create a very bright sun, and a relatively dark world (think of a sunset!) with an Ambient setting of zero, but if you want to simulate mid-day illumination while the the sun was low in the sky, you need to increase the Ambient setting.
 
'''Scene Gamma:''' This control functions similarly to the '''Gamma''' setting in the Graphics Hardware Settings (formerly Adv. Graphics) tab. It adjusts your screen's distribution of light and dark output. Lower settings will cause everything to appear dim, while higher settings may make the scene look gray and "washed out". '''Scene Gamma''' is more precise than the older '''Gamma''' in that it only affects your rendered view of the SL world- not the menus and rest of your computer's screen.
 
'''Star Brightness:''' Star Brightness defines how visible the stars are in the sky. If you play with this slider while the sun is up, you can see stars in the middle of the day!
 
===The Clouds Tab===
 
[[Image:kbsd_Kb_sky_clouds_menu_2.jpg]]
 
This tab gives you control over the clouds in the sky:
 
'''Cloud Color:''' This affects the color of your clouds, if you have any. Use the individual Red/Green/Blue sliders to change the color, or the Intensity (I) slider to drag all three at once.
 
'''Cloud XY/Density:''' Use the '''X''' and '''Y''' sliders to change the horizontal position of all clouds in the sky. The '''D''' slider affects the overall density of the individual clouds; at low settings you will see thin, wispy clouds, and at higher settings you will see thicker, more solid clouds.
 
'''Cloud Coverage:''' As the name implies, this control sets the amount of cloud coverage. At zero, there isn't a cloud in the sky, but at higher settings, you can get a completely overcast effect.
 
'''Cloud Scale:''' This setting affects the perceived altitude of the clouds... if you slide the control to the right, it will make the clouds appear to be higher in the sky.
 
'''Cloud Detail (XY/Density):''' These settings affect the detail imagery of your clouds. The '''X''' and '''Y''' sliders shift its horizontal position, and the '''D''' slider controls how puffy and/or fractured your clouds look.
 
'''Cloud Scroll X and Cloud Scroll Y:''' These sliders affect the direction and speed at which the clouds float in the sky. You may also check the '''Lock''' checkbox to prevent clouds from moving on the selected axis.
 
'''Draw Classic Clouds:''' Check this box to enable rendering of Second Life's classic clouds in addition to WindLight's clouds.
 
===Sky Presets===
 
Along the top of the Advanced Sky Editor window you'll find controls for creating, loading, saving, and deleting Sky Presets. Sky Presets are essentially snapshots of WindLight slider settings you can re-load later or use as keyframes in the Day Cycle Editor. To create a new preset, simply press the '''New''' button and name your preset. It will, by default, have the settings currently loaded in the WindLight sliders. To load a preset, simply pick it from the drop-down menu of Sky Presets. Deleting a preset is as easy as pressing the '''Delete''' button once it's loaded. Creating presets is useful both for re-loading your favorite settings and for creating day cycle animations using the [[Day Cycle Editor]].
