# Material

Encapsulate a set of shader graph nodes into a single module.

## Overview

`Material` nodes help you divide your graph into subsets of nodes, each with distinct inputs and outputs. A [`Node Graph`](/documentation/ShaderGraph/Material/Node-Graph) appears as a single node within your main graph. Editing that node hides the main graph and gives you an empty space that you fill with additional nodes. Use that space to build a specific portion of your main graph, and use the [`Node Graph`](/documentation/ShaderGraph/Material/Node-Graph) to define the inputs and outputs to that separate space.

## Topics

### Nodes

[`Node Graph`](/documentation/ShaderGraph/Material/Node-Graph)

A node that can contain shading nodes and other node graphs.
