Lightmapped Shader Family

Lightmapped shaders are like Self-Illuminated shaders on steroids. They use a secondary Lightmap texture that defines light "emitted" from the object onto itself (and nothing else). The Lightmap texture also uses the secondary UV map of the mesh for controlling the placement of light, which can differ from the primary UV map. These shaders allows you to use baked colored light, radiosity with color bleeding and other interesting effects.

In-game lights add on top of the illumination that is present in the lightmap. For example, the scene in the following pages with no lights at all looks like below. All the illumination on the model comes only from the lightmap.
