    Hi, I'd like to use the stencil functionality to discard fragments. But I only know during runtimeI what materials I'm working with. So I can't modify them before.
    Is there any way for example to replace the original shader inside a material and to call the original shader with all it's properties from the replacement shader in case the replacement passes the stencil test?

    Sadly, no, there is no way of doing this. Unity has this functionality internally and use it for sprite and deferred rendering, but it’s not exposed to c# outside of custom SRP rendering, and URP render features.

    Thanks a lot for the quick answer :) And there isn't somehow a way to put code into cginc that is automatically called by any shader?
