A state is an object that records changes to your scene allowing you to quickly display and render them. The typical workflow is as follows:
To create states:
The State Sets dialog opens showing a State Sets item at the top of the Tree View, with State01 underneath it. This default state is also known as the base state.
The state now lists all recorded changes. You can adjust these changes by expanding any entry and modifying its values.
To toggle between the base state and a recorded state, click the state's arrow button. You can also switch between different states by clicking the corresponding arrow button. Only one state can be active at a time. If no arrows are highlighted, no state is active and the original scene is shown.
To perform render passes:
State sets renders the states to files using the file pattern specified on the Render Outputs panel.
To create and export composites:
State Sets opens the Compositor view containing a fully-wired schematic. Each state is represented by a node that is wired to an Output Bitmap node containing a thumbnail of the state's rendered image. All the Output Bitmap nodes are wired to the Compositor Output node, which contains a thumbnail that shows the default composition.
In Compositor view, edit the schematic and nodes to modify the composite.
