Hi Simon
The parent actors are the way we represent the objects in the scene. Due to the plugin restrictions the object's geometry can only be stored in leaf nodes. so we need to keep two nodes one with the metadata and a child node with the tessellation.
We discuss the possibility to merge those two nodes, this will keep the geometry and data together. However, this is a large change that cannot be part of SP4, so we are considering 2023 as the potential target.
