I tried and it seems that the renderer feature is not recognized by the FOW script.
I am getting this warning : "The Fog of War feature is enabled but the shader was not yet applied. It seems like you are using URP or LWRP and did not add the custom render feature. Please visit the documentation to see which additional steps are needed to enable this feature in URP and LWRP."
I tried it and it worked. You have to make sure that you’re editing the correct Renderer2D.cs file. The location of the file on my system was “Project root\Library\PackageCache\com.unity.render-pipelines.universal@8.2.0\Runtime\2D”. When you paste the snippet to that file, try to add some debug message to that function to make sure that the Setup function is really called. Then I followed the instructions. I added the Fog of War URP feature to the Forward Renderer and from there I assigned is to the Renderer Features field of the 2D renderer and it worked.
