Configure settings with the URP Config package

You can use the Universal 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 (URP) Config package to control some of the settings of URP. Unity automatically adds the package files in the package cache as they are a dependency of URP, but you must make a copy of them in your project before you can use the package.

The URP Config Package currently only changes one setting which is the maximum number of visible lights URP renders when you use the Forward+ Rendering PathThe technique that a render pipeline uses to render graphics. Choosing a different rendering path affects how lighting and shading are calculated. Some rendering paths are more suited to different platforms and hardware than others. More info
See in Glossary. For more information, refer to Change the maximum number of visible lights.

Set up the URP Config package

To create a usable copy of the URP Config package in your project, do the following:

1. In the Project window, right-click Assets and select Show in Explorer (MacOS: Reveal in Finder).
2. Go to /Library/PackageCache/.
3. Copy the com.unity.render-pipelines.universal-config folder to the Packages folder.

The URP Config package is now ready for use in your project.

Configure URP with the URP Config package

You can edit the ShaderConfig.cs file to configure the properties of your URP project. If you edit this file, you must also update the equivalent ShaderConfig.cs.hlsl header file so that it mirrors the definitions you set in ShaderConfig.cs.

You can update the ShaderConfig.cs.hlsl file in two ways:

• Manually edit the ShaderConfig.cs.hlsl file to mirror the ShaderConfig.cs file. This method is faster but more likely to result in an error due to a mistake.
• Use the Editor to generate the ShaderConfig.cs.hlsl file from the ShaderConfig.cs file, which might take longer than a manual edit but ensures that the two files are synchronized.

To use the Editor to generate the ShaderConfig.cs.hlsl file, follow these steps:

1. In the Project window, go to Packages > Universal RP Config > Runtime and open ShaderConfig.cs.
2. Edit the values of the properties you want to change and then save and close the file.
3. In the Editor, select Edit > Rendering > Generate Shader Includes.
4. Unity automatically configures your project and shadersA program that runs on the GPU. More info
   See in Glossary to use the new configuration.

Update the URP Config package

When you use the Package Manager to update your URP package, the Package Manager downloads the latest version of the URP Config package to the /Library/PackageCache/ folder, but doesn’t automatically update the files of the URP Config package in your Packages folder. Instead, you need to manually update your copy of the URP Config package in your Packages folder and reapply your changes. To do this, use the following steps:

1. Make a copy of the com.unity.render-pipelines.universal-config from your Packages folder. You can reference this later when you reapply your changes.
2. Delete the com.unity.render-pipelines.universal-config folder in your Packages folder.
3. Copy the com.unity.render-pipelines.universal-config folder again from the /Library/PackageCache/ folder to your Packages folder, as shown above in the Set up the URP Config package section.
4. Manually reapply your modifications to the updated copy of the URP Config package.
