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:
lightmapDir if you use LightmapsMode.CombinedDirectional.
shadowMask if you use MixedLightingMode.Shadowmask.

| lightmapColor | Lightmap storing color of incoming light. |
| lightmapDir | Lightmap storing dominant direction of incoming light. |
| shadowMask | Texture storing occlusion mask per light (ShadowMask, up to four lights). |
