ライトマップのデータを格納しています。
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. See Also: LightmapSettings クラス, Renderer.lightmapIndex
