The light map

The light map is just that - it is a map of the light intensity on the surface of the heightfield. It is used when generating the texture map.

The sunlight used in this map was yellow-white, but it can be any RGB colour you like. Note that the water absorption option has been used here, thus the seafloor is very dark, and shallows are green-blue.
