Upgrading your Shaders
If your Project uses shaders from the built-in render pipeline, and you want to switch your Project to use the Universal Render Pipeline instead, you must convert those Shaders to the URP Shaders. This is because built-in Lit shaders are not compatible with URP Shaders. For an overview of the mapping between built-in shaders and URP Shaders, see Shader mappings.
To upgrade built-in Shaders:
- Open your Project in Unity, and go to Edit > Rendering > Materials.
- According to your needs, select either Convert All Built-in Project Materials to URP or Convert Selected Built-in Materials to URP.
Note: These changes cannot be undone. Backup your Project before you upgrade it.
Tip: If the Preview thumbnails in Project View are incorrect after you've upgraded, try right-clicking anywhere in the Project View window 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 table below shows which URP shaders the Unity built-in shaders convert to when you run the shader upgrader.
