Group
Group Nodes are a collection of nodes that can be combined into a single node while selectively exposing inputs of the embedded nodes. Group nodes can simplify a node tree by allowing instancing and hiding parts of the tree.
Make Group
Creates a node group from the selected nodes, see Make Group for more information.
Ungroup
Removes the selected nodes from a group, see Ungroup for more information.
Group Input
Adds a group input node, this serves as a convenient way to re-add the input node in case it is accidentally deleted. Note, groups can only have one input, if more than one is added they are duplicates of each other.
Group Output
Adds a group output node, this serves as a convenient way to re-add the output node in case it is accidentally deleted. Note, groups can only have one output, if more than one is added they are duplicates of each other.
Node Groups
This section lists all the node groups either from the current blend-file or Linked or Appended from another blend-file.
