    Hi, I was trying to implement an equivalent of UE4s' Depth Fade node. In the source code they define it as 
    Opacity * saturate((SceneDepth - PixelDepth) / max(FadeDistance, DELTA))


    Here's what I got in the Shader Graph editor

    On the left I have pasted UE'4 color output for that node. However the result of those nodes look completely black. Does anybody know how to fix that? Thanks in advance.

    Solved it by myself: apparently the URP does not generate Depth textures by default. It needs to be enabled in the SRP options. Posting this for posterity :)

    Thanks for the implementation, but what does delta equal to?

    A very small value above zero, like 0.000001, because dividing by zero is bad.

    Did you get this to work like the UE Depth node? Were the results good?
