You can automatically organize your layer-related nodes into containers, making it easier to see the connections between your objects and layers in the Hypergraph.
To organize layers into containers
A container is created for each layer in the stack. A container called BaseAnimation_Container is also created to encapsulate the base animation curves for objects that have animation layers. (Base animation curves are those that existed before layers were added for the objects.)
The related nodes for each layer (including the layer node, blend nodes, and animation curves) are automatically placed in its container. The layer node is added at the top level, and the blend nodes and animation curves are each grouped in separate sub-containers.
