SIObject ProjectItem SceneItem Group Partition
A Partition is a division of a Pass, which behaves like a Group. Partitions are used to organize scene elements within a Pass. There are only two types of partitions: object and light. Light partitions can only contain lights, and object partitions can only contain geometric objects.
Each pass created has at least two partitions: a background objects partition, which contains most or all of the scene's objects, and a background lights partition, which contains most or all of the scene's lights.
