Group Nodes

A Group node acts as a container for a sub-network of nodes. To add a Group node to a recipe under the root

location, then create a PrimitiveCreate node inside that group enter the following:

# Create a Group node at root, referenced as group

group = NodegraphAPI.CreateNode( 'Group', root )

Then, create a PrimitiveCreate, as in Creating a New Node but give the Group node as the level to create at, rather

than root as in the previous example:

groupChildNode = NodegraphAPI.CreateNode\

( 'PrimitiveCreate', group )

Alternatively, create a Group node and a PrimitiveCreate node at the root level, then parent the PrimitiveCreate node

under the Group node:

# Get the root node

root = NodegraphAPI.GetRootNode()

# Create the Group node at root level

group = NodegraphAPI.CreateNode( 'Group', root )

# Create the PrimitiveCreate node at root level

node = NodegraphAPI.CreateNode('PrimitiveCreate', root)

# Set the Group node as parent of the PrimitiveCreate node

node.setParent( group )

NOTE: Groups can be nested arbitrarily to form a Node Graph tree.
