13 | Basics Windows and Editors Reference > Hypergraph overview In many cases, you must be familiar with Maya internal operation details to understand the node and attribute names you see in the white boxes. Create Render Node... Create a render node with a texture map in the Hypergraph. Options Menu Display > Shape Nodes, Hidden Nodes, Underworld Nodes By default, the scene hierarchy does not display shape nodes, hidden nodes, or underworld nodes. It displays only transform nodes-nodes that hold attributes and other information on an object's transformation and parentchild relationships. Shape node-holds an object's geometry attributes or attributes other than the object's transform node attributes. A shape node is a child of a transform node. A transform node has only one shape node. Hidden node-any object hidden using Display > Hide from Maya's menu bar. The default cameras top, front, side, and persp are also hidden nodes. Underworld node-a pair of nodes below a shape node. When you create a curve on a NURBS surface, Maya generates an underworld transform node and shape node below the shape node of the surface. The CV positions of underworld nodes have UV coordinates on the surface rather than coordinates in world or local space. A dotted line in the scene hierarchy indicates a connection to an underworld node. Connections to instanced objects are also indicated by dotted lines. Note Hypergraph option settings are saved with a scene file. The options are not saved for Maya globally. Example 1 If you select Create > NURBS Primitives > Sphere to create a sphere, Maya creates a transform node and a shape node. The sphere's shape node holds the mathematical description of the sphere's shape. The sphere's transform node holds the sphere's position, scaling, rotation, and so on. The shape node is the child of the transform node. If you select Options > Display > Shape Nodes in the Hypergraph, the scene hierarchy shows these nodes for the sphere: Basics 399
