# Custom rendering and post-processing for 2D in URP

> Techniques for customizing and extending the rendering process using Scriptable Renderer Feature 2D in URP.

Customize and extend the rendering process in the Universal Render Pipeline (URP) in a 2D project. Create a custom render pass in a C# script and inject it into the URP frame rendering loop.
