  When filtering, classes support single selection, and attributes support multiple selections. When selecting multiple attributes, only the instances that contain all the selected attribute values are exposed.
• Track ID Filter
  Instances only in the scene file that are set to the same track ID are exposed. The Track ID filter is only activated when loading 'Thumbnail Viewer' for a single scene file in a dataset or studio.
