| lightIndexMap | Array with light indices that map from VisibleLight to internal per-object light lists. |
If a RenderPipeline sorts or otherwise modifies the VisibleLight list, an index remap will be necessary to properly make use of per-object light lists.
If an element of the array is set to -1, the light corresponding to that element will be disabled. Additional resources:: CullingResults.GetLightIndexMap, CullingResults.
