Data of a lightmap.

A Scene can have several lightmaps stored in it, and Renderer components can use those lightmaps. This makes it possible to use the same material on multiple objects, while each object can refer to a different lightmap or different portion of the same lightmap.

You must set the following properties or Unity might render objects incorrectly:

lightmapColorLightmap storing color of incoming light.
lightmapDirLightmap storing dominant direction of incoming light.
shadowMaskTexture storing occlusion mask per light (ShadowMask, up to four lights).
