Sun Direction

"Sundir in spring is a vector of X Y Z. If you look at the map in the TA camera (default) left is -X, right is +X up is Y, down is -Y, backwards is -Z and forwards is Z." - Beherith [1]

Sun Colour

The color of the sun in the sky. The values are in the order Red, Green, Blue. This will also effect the size of the star. As the values increase (including over 1.0), the disc will get bigger; the inverse is also true.
