A point cloud encoding device includes a point cloud encoding device includes a communication interface and a processor operably coupled to the communication interface. The communication interface is configured to receive a plurality of independent bitstreams. The communication interface is also configured to receive a grouping message indicating a group of assets from the plurality of independent bitstreams containing visual volumetric coding (V3C) content. The processor is configured to select the group of assets based on the grouping message. The processor is configured to decode at least the selected group of assets.
