# Lit

The Lit Master Stack enables you to render custom physically-based materials in the High Definition Render Pipeline (HDRP). It supports various effects, such as subsurface scattering, anisotropy, iridescence, specular color and translucency.

## Creating a Lit Shader Graph

To create a Lit material in Shader Graph, you can either:

* Modify an existing Shader Graph.
    1. Open the Shader Graph in the Shader Editor.
    2. In **Graph Settings**, select the **HDRP** Target. If there isn't one, go to **Active Targets,** click the **Plus** button, and select **HDRP**.
    3. In the **Material** drop-down, select **Lit**.

* Create a new Shader Graph.
    1. Go to **Assets > Create >Shader Graph > HDRP** and click **Lit Shader Graph**.

## Contexts

[!include[](snippets/master-stacks-contexts-intro.md)]

### Vertex Context

#### Default

When you create a new Lit Master Stack, the Vertex Context contains the following Blocks by default:

<table>
<tr>
<th>Property</th>
<th>Description</th>
<th>Setting Dependency</th>
<th>Default Value</th>
</tr>
[!include[](snippets/shader-graph-blocks/vertex-position.md)]
[!include[](snippets/shader-graph-blocks/vertex-normal.md)]
[!include[](snippets/shader-graph-blocks/vertex-tangent.md)]
</table>

#### Relevant

This Master Stack material type adds all its Vertex Blocks to the Vertex Context by default and has no extra relevant Blocks.

### Fragment Context

#### Default

When you create a new Lit Master Stack, the Fragment Context contains the following Blocks by default:

<table>
<tr>
<th>Property</th>
<th>Description</th>
<th>Setting Dependency</th>
<th>Default Value</th>

Depending on the [Graph Settings](#graph-settings) you use, Shader Graph can add the following Blocks to the Fragment Context:
