# Sink Pin The **`Sink`** pin is a unique tool for creating an endpoint for the nodegraph. When you create a **`Sink`** node, you essentially generate the node that initiates the execution of the entire nodegraph. The **`Sink`** node acts as the terminal point of your nodegraph, where the final processed output is directed. In cases where you lack an AJA card and, consequently, can't create **`AJAIn`** and **`AJAOut`** nodes for video I/O connections, the **`Sink`** Node becomes a handy tool. Without direct hardware connections, the **`Sink`** node allows you to process and manipulate data within the Reality Hub environment. ### Creating Sink Node * Hover over the output pin of your desired node.

* Hold the left mouse button and drag, then release it. * In the **Node Creation Menu**, locate and click on the **Sink** button.
