Configuring the AR Camera background using a Scriptable Render Pipeline

AR Foundation supports the Universal Render Pipeline (URP) versions 7.0.0 or later. See the URP Install and Configure documentation for more details on switching to URP.

[!NOTE] Projects made using URP are not compatible with the High Definition Render Pipeline or the built-in Unity rendering pipeline. Before you start development, you must decide which render pipeline to use in your project.

Basic URP configuration for AR Foundation

Set up URP Render Pipeline asset

[!NOTE] The following basic steps for URP setup are not specific to AR Foundation and are included to indicate how to convert a legacy AR Foundation project into a URP AR Foundation project. If your project was created from the URP Project Template or you already have a UniversalRenderPipelineAsset and Pipeline Asset (Forward Renderer) in your project, skip to the next section.

To use the Universal Rendering Pipeline, you must create a Pipeline Asset. Follow these steps:

1. In the project's Assets folder, create a new folder named Rendering.
2. In the Rendering folder, create a Pipeline Asset (Forward Renderer) for URP: Right-click anywhere in the folder and select Create > Rendering > Universal Render Pipeline > Pipeline Asset (Forward Renderer) from the context menu. This creates two assets:
   • A UniversalRenderPipelineAsset
   • A ForwardRenderer

Configuring URP to work with ARFoundation

After you created a Pipeline Asset, you can configure the asset to work with AR Foundation. Follow these steps:

1. Locate your Forward Renderer asset. If you created your project from the URP Project Template, this is located in the Settings folder in your project's Assets folder.
2. Select your Forward Renderer asset. In its Inspector, add an ARBackgroundRendererFeature to the list of Renderer Features.
3. Access the Graphics section of the Project Settings window (menu: Edit > Project Settings, then select Graphics), and select the UniversalRenderPipelineAsset in the Scriptable Render Pipeline Settings field.
