# Operator Group

> **Note:** **What is it about?**
>
> This page covers the **Operator Group node** of the Scene Nodes system in **Cinema 4D**. It provides the empty group shell with Op inputs and outputs — the frame in which custom operators are assembled.

As with the Primitive, Field and Effector group Nodes, you will find here a Node that at first offers no function but has to be fed with Nodes by you. This Node makes the typical inputs and outputs for **Op Input** and **Op Output** available. Additional inputs can be added individually (right-click on the opened group and select Add Input / Add New Input) or Output / Add New Output).

The Node can be opened by clicking on the Folder symbol at the top of the Node.
