There are two types of Point Clouds in our Visualize API. Unstructured and RCS based. Auto LOD is available only for RCS based Point Cloud. Both types can be stored in VSF file. But if the unstructured point cloud stores all it's data in VSF, the RCS based point cloud stores only a link to the appropriate *.rcs file. Also there is ability to convert unstructured point cloud to the RCS based.
