# Import a file from the URP shader library
|
||
|
|
|
||
|
|
The High-Level Shader Language (HLSL) shader files for the Universal Render Pipeline (URP) are in the `Packages/com.unity.render-pipelines.universal/ShaderLibrary/` folder in your project.
|
||
|
|
|
||
|
|
To import a shader file into a custom shader file, add an `#include` directive inside the `HLSLPROGRAM` in your shader file. For example:
|
||
|
|
|
||
|
|
```hlsl
|
||
|
|
HLSLPROGRAM
|
||
|
|
...
|
||
|
|
#include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl"
|
||
|
|
...
|
||
|
|
ENDHLSL
|
||
|
|
```
|
||
|
|
|
||
|
|
You can then use the helper methods from the file. For example:
|
||
|
|
|
||
|
|
```hlsl
|
||
|
|
float3 cameraPosition = GetCameraPositionWS();
|
||
|
|
```
|
||
|
|
|
||
|
|
Refer to [Shader methods in URP](use-built-in-shader-methods.md) for more information about the different shader files.
|
||
|
|
|
||
|
|
You can also import shader files from the core Scriptable Render Pipeline (SRP). Refer to [Shader methods in Scriptable Render Pipeline (SRP) Core](https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@17.0/manual/built-in-shader-methods.html).

## Examples
|
||
|
|
|
||
|
|
Refer to [Writing custom shaders](writing-custom-shaders-urp.md) for examples of using variables and helper methods from the files in the URP shader library.
