Shader methods in URP

The Universal Render Pipeline (URP) has a library of High-Level Shader Language (HLSL) shader files that contain helper methods. You can import these files into your custom shader files and use the helper methods.

Page	Description
Import a file from the URP shader library	Use the #include directive in HLSL to import a URP shader file.
Transform positions in a custom URP shader	Transform vertex, fragment, normal and tangent positions between coordinate spaces.
Use the camera in a custom URP shader	Get the position and direction of the camera.
Use lighting in a custom URP shader	Get the lights in a scene, and calculate lighting.
Use shadows in a custom URP shader	Get shadow data from lights in the scene, and calculate shadows.
