Creating a custom render pipeline
Creating a Render Pipeline Asset and Render Pipeline Instance in a custom render pipeline
Creating a custom render pipeline based on the Scriptable Render Pipeline
This page contains information on how to get started with creating your own custom render pipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary based on the Scriptable Render Pipeline (SRP).
Creating a new project and installing the packages needed for a custom render pipeline
These instructions show you how to create a custom render pipeline using the SRP Core package. SRP Core is a package made by Unity that contains a reusable code to help you make your own render pipeline, including boilerplate code for working with platform-specific graphics APIs, utility functions for common rendering operations, and the shaderA program that runs on the GPU. More info
See in Glossary library that URP and HDRP use. For more information on SRP Core, see the SRP Core package documentation.
- Create a new Unity Project.
- Use Git to create a clone of the SRP source code repository. You can place the SRP source code in any location on your disk, as long as it is not in one of the reserved Project sub-folders.
- Use Git to update your copy of the SRP source code to a branch that is compatible with your version of the Unity Editor. Read Using the latest version in the SRP repository documentation for information on branches and versions.
- Open your Project in Unity, and install the following packages from the SRP source code folder on your disk, in the following order. For information on installing packages from disk, see Installing a package from a local folder.
-
com.unity.render-pipelines.core.
- Optional: com.unity.render-pipelines.shadergraph. Install this package if you intend to use Shader Graph or modify the Shader Graph source code as part of your custom SRP.
- Optional: com.unity.render-pipelines.visualeffectgraph. Install this package if you intend to use Visual Effect Graph or modify the Visual Effect Graph source code as part of your custom SRP.
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.
Creating a custom version of URP or HDRP
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:
URP:
- com.unity.render-pipelines.core
- com.unity.render-pipelines.shadergraph
- com.unity.render-pipelines.universal
HDRP:
- com.unity.render-pipelines.core
- com.unity.render-pipelines.shadergraph
- com.unity.render-pipelines.high-defintion
