Unity provides two prebuilt Scriptable Render Pipelines (SRPs): the High Definition Render Pipeline (HDRP), and the Universal Render Pipeline (URP). HDRP and URP offer extensive customization options. However, if you want even more control over your renderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
See in Glossary pipeline, you can create your own custom SRP.
These instructions show you how to create a custom SRP using the SRP Core package. SRP Core is a package made by Unity that contains a reusable code to help you make your own SRP, including boilerplate code for working with platform-specific graphics APIs, utility functions for common rendering operations, and the shaderA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info
See in Glossary library that URP and HDRP use. For more information on SRP Core, see the SRP Core package documentation.
You can now debug and modify the scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary in your copy of the SRP source code, and see the results of your changes in your Unity Project.
The Universal Render Pipeline (URP) and the High Definition Render Pipeline (HDRP) offer extensive customization options to help you achieve the graphics and performance you need. However, if you want even more control, you can create a custom version of one of these render pipelines, and modify the source code.
Follow steps 1–3 in the section above, Creating a new Project and installing the packages needed for a custom SRP. When you reach step 4, install the following packages in the following order:
