A binding set creates a mapping of node attributes to published names in the template file. When you apply the template to another asset in Maya, you can then use the Autobind feature to automatically publish and bind the attributes to that asset based on the binding set.
To create a binding set
Maya adds binding set information to the template.
If you have published names that are not bound to published attributes, the binding set maps them to a placeholder value.
You can update the binding set at any time with additional published attributes or names.
To update a binding set
Maya updates the binding set in the template file.
You can remove a binding set from a template by selecting Template > Remove Binding Set.
