Connect container attributes

User Guide > General > Basics > Assets > Editing Assets >

You can connect containers to other containers or nodes in the Hypergraph Connections editor and Hypershade by dragging connections. Before you can do this though, you must publish the output attributes of an internal node to the container.

To create a new connection from a container to an external node

Expand the container in the Hypergraph Connections editor or the Work Area of the Hypershade.
Select the internal node whose attribute you want to connect.
Publish the attribute. (See Publish or unpublish attributes.)
Collapse the container.
-click the bottom-right corner of the container (a small empty arrow) and select the output attribute from the list.
Maya draws a line from the node to the mouse.
Click the node you want to connect the container to.
A list of input attributes is listed when you hold the mouse button.
Select the input attribute from the list.
Maya creates a connection between the two attributes.

NoteYou can also create a connection from an external node to a container using the same workflow but starting with the external node instead of the container.

NoteIf the list appears empty when you click the bottom-right corner of the container, it is because you did not publish an output attribute.

You can also the container onto an external node and select an attribute to connect to from the list that appears. This opens the Connection Editor where you can setup multiple connections at once.
