You can merge multiple animation layers together to create a single layer with all of the same objects, attributes, and animation.
You can merge animation layers using the default merge options, or open the Merge Layers Options to specify how you want the merge to occur.
To merge animation layers with default options
A new layer containing all objects, attributes, and animation from the merged layers is created.
The merged layers are deleted from the stack and the new layer takes the place of whichever merged layer is lowest in the stack.
To set merge options and merge animation layers
A new layer containing all objects, attributes, and animation from the merged layers is created.
