    I am using URP with differed rendering. I want to insert a pass, through "renderer feature", to modify normal buffer, BUT I have no idea how to set it up as an input, how to sample and how to write back normal buffer. I don't even know if that's possible. Can anybody point to the right direction?

    I also would love to know. There doesn't seem to be adequate documentation on these features that I can find

    Hi, I think the normal buffer is a render texture called "_CameraNormalsTexture" in URP.


    In URP 12 and below, you can:

    ScriptableRenderPass.ConfigureTarget("_CameraNormalsTexture", depth buffer);


    In URP 12+, URP uses RTHandle, see the methods in URP - Change Render Target (#6 & #7).
