Use the Number_Of_Rays parameter to change the number of rays coming out of the sun. The rays increase in size as they get farther away from the sun. Use the Ray_Size parameter to set the relative size
of the rays. If the Ray_Size parameter is set to 0%, there will be no ray. If Ray_Size is set to 100%, there
will be no gaps between the rays. Ray_Size can be linked to a generator, which will set the width of the rays from the center out.
Use the Sun_Size parameter to change the size of the sun. Set it to 0% to eliminate the sun. If Sun_Size is set to 100%, the sun will fill almost the entire default region.
The Blend_Function controls the blend from the background to the rays. The default Blend_Function makes the rays extend all the way to the edge.
Use the Sun_Profile and Ray_Profile parameters in the bump version to control the Bevel_Profiles for the
sun and rays, respectively. Both work from the outside edge to the center. The default for both of them is a quarter round.
