The 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 Converter converts assets made for a Built-in Render Pipeline project to assets compatible with URP.
Note: The conversion process makes irreversible changes to the project. Back up your project before the conversion.
To convert project assets:
Select Window > Rendering > Render Pipeline Converter. Unity opens the Render Pipeline Converter window.
Select the conversion type.
Depending on the conversion type, the dialog shows the available converters. Select or clear the check boxes next to converter names to enable or disable the converters.
For the list of available converters, refer to the section Converters.
Click Initialize Converters. The Render Pipeline Converter preprocesses the assets in the project and shows the list of elements to convert. Select or clear check boxes next to assets to include or exclude them from the conversion process.
The following illustration shows initialized converters.
Click a converter to check the list of items that a converter is about to convert.
Yellow icon: a yellow icon next to an element indicates that a user action might be required to run the conversion. Hover the mouse pointer over the icon to check the description of the issue.
Click Convert Assets to start the conversion process.
Note: The conversion process makes irreversible changes to the project. Back up your project before the conversion.
When the conversion process finishes, the window shows the status of each converter.
Green check mark: the conversion went without issues.
Yellow icon: the conversion finished with warnings and might require user action.
Red icon: the conversion failed.
Click a converter to check the list of processed items in that converter.
After reviewing the converted project, close the Render Pipeline Converter window.
The Render Pipeline Converter let’s you select one of the following conversion types:
Built-in Render Pipeline to URP
Built-in Render Pipeline 2D to URP 2D
Upgrade 2D URP Assets
When you select on of the conversion types, the tool shows you the available converters.
The following sections describe the converters available for each conversion type.
This conversion type converts project elements from the Built-in Render Pipeline to URP.
Available converters:
Rendering Settings
This converter creates the URP Asset and Renderer assets. Then the converter evaluates the settings in the Built-in Render Pipeline project and converts them into equivalent properties in the URP assets.
Material Upgrade
This converter converts the Materials. The converter works on pre-built Materials that are supplied by Unity, it does not support Materials with custom shadersA program that runs on the GPU. More info
See in Glossary.
Animation ClipAnimation data that can be used for animated characters or simple animations. It is a simple “unit” piece of motion, such as (one specific instance of) “Idle”, “Walk” or “Run”. More info
See in Glossary Converter
This converter converts the animation clips. It runs after the Material Upgrade converter finishes.
Note: This converter is available only if the project contains animations that affect the properties of Materials, or Post-processing Stack v2 properties.
Read-only Material Converter
This converter converts the pre-built read-only Materials, where the Material Upgrade converter cannot replace the shader. This converter indexes the project and creates a temporary .index
file, which might take a significant time.
Examples of read-only Materials: Default-Diffuse
, Default-Line
, Dafault-Terrain-Diffuse
, etc.
Post-ProcessingA process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info post processing, postprocessing, postprocess
See in Glossary Stack v2 Converter
This converter converts PPv2 Volumes, Profiles, and Layers to URP Volumes, Profiles, and CamerasA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary. This converter indexes the project and creates a temporary .index
file, which might take a significant time.
This conversion type converts elements of a project from Built-in Render Pipeline 2D to URP 2D.
Available converters:
Material and Material Reference Upgrade
This converter converts all Materials and Material references from Built-in Render Pipeline 2D to URP 2D.
This conversion type upgrades assets of a 2D project from an earlier URP version to the current URP version.
Available converters:
Parametric to Freeform Light Upgrade
This converter converts all parametric lights to freeform lights.
The Render Pipeline Converter implements the Converters class with RunInBatchMode methods that let you run the conversion process from a command line.
For example, the following script initializes and executes the converters Material Upgrade, and Read-only Material Converter.
using System.Collections; using System.Collections.Generic; using UnityEditor; using UnityEditor.Rendering.Universal; using UnityEngine; public class MyUpgradeScript : MonoBehaviour { public static void ConvertBuiltinToURPMaterials() { Converters.RunInBatchMode( ConverterContainerId.BuiltInToURP , new List<ConverterId> { ConverterId.Material, ConverterId.ReadonlyMaterial } , ConverterFilter.Inclusive ); EditorApplication.Exit(0); } }
To run the example conversion from the command line, use the following command:
"<path to Unity application> -projectPath <project path> -batchmode -executeMethod MyUpgradeScript.ConvertBuiltinToURPMaterials
Also check: Unity Editor command line arguments.
