Remarks

Transient override lightmap data, used by landscape grass. Be sure to add your component to UMapBuildDataRegistry::CleanupTransientOverrideMapBuildData() for proper cleanup so that you don't get stale rendering resource references if the underlying MapBuildData is gone (lighting scenario changes, new static lighting build, etc.)
