      Effect:Sky with Clouds
      Category:Procedural Sources
      Speed:Slow

      Description: The Sky with Clouds Effect creates 3D cloud filled skies using Color 1 for the cloud color and Color 2 for the sky color. For realistic results use white for Color 1 (R=255, G=255, B=255) and a dark sky blue for Color 2 (R=86, G=86, B=255).

      The Sky with Clouds Effect is time sensitive and can use a Clock or Clock Modifier (available in the Sky with Clouds Options) to modify the Effect over time.

      If you enable the Fit To Brush Option you will paint with the Sky with Clouds Effect sized to your brush.

       
      Options: The Sky with Clouds Effect has the following Options Pane:

      Clock:This Effect can change over time. This control lets you select which of the four Clocks to use (Clocks are assigned in the Brush Pane). Any Green Colored Clock is the one currently in use. Tap the reset button and a Pop Up will appear that lets you reset any of the four Clocks to their initial value. Yellow colored clocks are not in use. Note that you can turn Clocks off by tapping a Green Clock turning all of them yellow.
      Clock Modifier:This value is added to the current Clock. You can use this to change where in time this Effect is, relative to the Clock (this allows different Effects to use the same Clock with different offsets).
      Frequency:This value controls the amount of clouds. Low values give more wispy clouds, higher values give denser, more clumpy clouds.
      X Resolution:This value controls the density of the clouds in the X (horizontal) direction. Lower values are less dense, higher values are more dense.
      Y Resolution:This value controls the density of the clouds in the Y (vertical) direction. Lower values are less dense, higher values are more dense.
      X Position:This value controls the where the horizon is drawn in the X (horizontal) direction.
      Y Position:This value controls the where the horizon is drawn in the Y (vertical) direction.
      Fit To Brush:If set to a Red X the Effect spans the screen such that as you paint you reveal the Effect. When set to a Green Check Mark the Effect is sized to the brush such that as you paint the entire Effect is within the brush itself.
      Output Color 1:By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.
      Output Color 2:By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.

      Example: The following image shows the Sky with Clouds Effect with its default settings and Color 1 set to white, and Color 2 set to dark sky blue:

      Lowering the Frequency creates more wispy clouds:

      Raising the Frequency creates more clumpy, dense clouds:

      Here both the X and Y resolution have been greatly increased:

      Gentle changes to X and Y resolution, Frequency, and X Position can give subtle changes:

      Lowering the Y Position to .35 with the other default values centers the horizon in this next image:
