Group(グループ)
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.
Group Input(グループ入力)
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(グループ出力)
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(ノードグループ)
This section lists all the node groups either from the current blend-file or Linked or Appended from another blend-file.
