Chapter 15. Complex Projects > Recursive Switches

Recursive Switches

By default, controls for nested compositions operate recursively. That is, setting a switch for a nested composition also sets the switch for the layers nested within it. These switches include Collapse Transformations/Continuously Rasterize, and Quality. The composition's Resolution, Enable Motion Blur setting, and Enable Frame Blending setting also operate recursively.

In general, recursive switches can save you time and effort. Sometimes, however, recursive switches can produce undesired results. In a complex project, for example, you might enable Collapse Transformations for a nested composition. If the nested composition contained yet another composition, its Collapse Transformations switch would be enabled as well. As a result, you might unintentionally bypass necessary masks and effects. Similarly, recursive switches could prevent you from enabling Motion Blur selectively in a series of nested compositions. As a rule, use recursive switches. If using a switch has unintended consequences, disable recursive switches.
