Converting your shaders

Shaders written for the Built-in Render Pipeline are not compatible with the URP shaders.

For an overview of the mapping between built-in shaders and URP shaders, see Shader mappings.

Use the Render Pipeline Converter to apply the shader mappings automatically.

NOTE: The Render Pipeline Converter makes irreversible changes to the project. Back up your project before the conversion.

TIP: If the preview thumbnails in the Project view are not shown correctly after the conversion, try right-clicking anywhere in the Project view and selecting Reimport All.

For SpeedTree Shaders, Unity does not re-generate Materials when you re-import them, unless you click the Generate Materials or Apply & Generate Materials button.

Shader mappings

The following table shows which URP shaders the Built-in Render Pipeline shaders convert to when you use the Render Pipeline Converter.
