I need to replace one shader include, will I need a complete fork of URP for that?

I need to change the file

com.unity.render-pipelines.universal\ShaderLibrary\Shadows.hlsl

. This file is included by a ton of other files, including shader graph generated ones. Is the best solution to fork URP completely, or is there a different way to inject it into the package?

 

I've made some changes to

RealtimeLights.hlsl

and I had to fork URP, by copying the whole

com.unity.render-pipelines.universal

to the

/Packages/

folder, otherwise Unity undoes any changes made. It's a pain when you upgrade to a new version of Unity which has a newer URP because you've got to do the same thing all over again, but I don't believe there's any other way.

 

Sigh... All right; thanks! Would be cool if Unity offered a way to inject these, especially for Asset Store extensions.
