Rainbows are automatically generated by trueSKY providing that a number of conditions are met.
Rainbows can be fully customised, from position to strength and colour of the rainbow.
|Automatic Rainbow Position||Whether the rainbow follows the antisolar/antilunar point, or is manually set.||Bool|
|Elevation||If the automatic positioning is disabled, this sets the elevation of the rainbow.||0.0 to -90.0|
|Azimuth||If the automatic positioning is disabled, this sets the azimuth of the rainbow.||0.0 to 360.0|
|Intensity||Controls the overall brightness of the rainbow.||0.0 to 10.0|
|Depth Position||The point at which the rainbow intersects the terrain. (Dependent a forward/reverse depth)||0.0 to 1.0|
|Allow Occluded Rainbows||Whether trueSKY should generate rainbows regardless of light occlusion.||Bool|
|Allow Lunar Rainbows||Whether trueSKY should generate rainbows using the moon’s light.||Bool|
|Rain Speed (m/s)||Speed at which raindrops will fall, which adjusts any ‘flutter’ seen in the Rain Streaks, which are used for the rainbow.||0.0 to 120.0|
|Raindrop Size (mm)||At sizes less than 1.0mm, trueSKY will use a Submillimetric Light Scattering Approximation to adjust the spectual output.||0.001 to 100.0|
|Strength||Adjusts the strength the rainbow.||0.0 to 1.0|
|Rain Streaks||Adjusts the strength the rainbow.||0.0 to 1.0|
Note: Both Rain Strength and Rain Streaks must be greated than 0 for rainbows to be generated.
