Declaration
struct LightmapComponentOverview
LightmapComponent specifies which children of its owning entity should have a lightmap applied to them, and connects those children to their corresponding data in a LightmapResource.
To use LightmapComponent, first create a LightmapResource using textures produced by an offline baking process. Then, create a new LightmapComponent backed by the LightmapResource, and use the entityIndexInLightmapResource property to map each entity that you wish to be lightmapped, to its corresponding slot in the lightmap resource. Finally, add the LightmapComponent to an entity that sits above all of the lightmapped entities in the hierachy.
