When using Portalgraph with URP, the following configuration is required to enable anaglyph rendering.
Select the Universal Render Pipeline Asset you are using (typically Assets/Settings/URP-HighFidelity or Assets/Settings/PC_RPAsset), and in the Inspector, set element 1 of the Renderer List to Assets/Portalgraph/Settings/Anaglyph Universal Renderer Data.
You can confirm which Universal Render Pipeline Asset is in use by checking the Graphics tab in the Project Settings.
