5 | Nodes and attributes About > Node types Basics 92 ™ "Hypergraph overview" on page 390 Node types Transform node A node that contains an object's transformation attributes-values for its translation, rotation, scale, and so on. It also holds information on parent-child relationships it has with other nodes. InnerSolarSystem, Sun, Moon, and all other boxes shown in the example are transform nodes. Shape nodes Holds an object's geometry attributes or attributes other than the object's transform node attributes. A shape node is the child of a transform node. A transform node has only one shape node. Auxiliary nodes There are several nodes, such as unitConversion, which are hidden to reduce clutter in the editors. They are not normally useful to see or edit; however, if you need to you can show these nodes. (You can also hide nodes that are normally shown if you want to further reduce clutter.) Hidden nodes Any object hidden using Display > Hide. Maya hides the default cameras (top, front, side, and persp) by default. Underworld nodes A pair of nodes below a shape node. When you create a curve-on-surface, Maya creates an underworld transform node and shape node for the curve-on-surface below the surface's shape node. The CV positions of underworld nodes have UV coordinates on the surface rather than coordinates in world or local space. Rendering nodes Materials and textures each have nodes containing attributes that control their look. Texture placement nodes have attributes that control how a texture is fitted onto a surface. Lights are of course nodes too, with attributes controlling their properties. Container nodes You can organize nodes within the dependency graph into logical node groupings using Container Nodes. A container node is a special type of node that lets you: • simplify the display of nodes related to a particular item in the scene.
