 ''' Sunlight Parameters'''
-*'''Heading:''' This parameter sets the heading of the sun in degrees.  You can think of 0° as North, +90° as East, +-180° as South, and -90° as West.  The parameter can be used as a slider with a range of -180 to +180 degrees, or by clicking on the numerical value to directly input an amount.
+*'''Heading:''' This parameter sets the heading of the sun in degrees.  You can think of 0° as North, +90° as East, +-180° as South, and -90° as West.  The parameter includes a slider with a range of -180 to +180 degrees, and a roller which can be dragged to the left or right to adjust its value, or to directly enter a numeric value.
-*'''Elevation:''' This parameter sets the elevation of the sun in degrees.  You can think of 0° being directly on the horizon, +90° being directly overhead, and -90° being on the underside of the planet.  When negative values are used to simulate a night sky, you can compensate for the darkness by increasing the Exposure value.  The parameter can be used as a slider with a range of -90 to +90 degrees, or by clicking on the numerical value to directly input an amount.

-*'''Colour:''' This parameter sets the colour of the selected Sunlight. The input allows you to set the value for the individual red, green and blue components that make up the Sunlight’s colour. Negative values are allowed. In the Sun Direction dial, the colour of the Sunlight will change as the colour value is changed.
+*'''Colour:''' This parameter sets the colour of the selected Sunlight. It consists of one roller for each of the components (red, green, blue) that make up the Sunlight's colour. To change the colour simply drag to the left or right in each roller, or enter a numeric value. Negative values are allowed. The Sun Direction dial will update to reflect the new colour values.
 *'''Strength:''' This parameter sets the intensity of the Sunlight.  The default strength value is 5.

 * '''Cloud Add''' and '''Cloud Remove''': Paint strokes created with the Cloud Add tool appear in green, while paint strokes created with the Cloud Remove tool are coloured purple.  Both tools allow you to set the brush size and opacity.  You can use the left “[“ and right “]” bracket keys to change the current tool’s brush size.  Paint strokes are grouped together into a layer when their size and opacity are the same.  A new layer is created whenever the size or opacity is changed and a new paint stroke is made.  You can edit the size and opacity of a paint stroke layer by simply hitting the Space Bar to enter into the Edit mode. Within the Edit mode, you can move paint strokes from one canvas to another.

 You can paint from multiple viewpoints. Up to 10 different camera positions can be stored as a viewpoint, and each viewpoint has its own set of cube maps. These are projected into 3D space and intersect with one another to provide a merged solution to where clouds should be added and removed in 3D space.
 Painting Viewpoints can be selected with the buttons at the top of the Viewport. You can hover over them to preview viewpoints temporarily without switching to them.
