Question LinearEyeDepth() in Shader Graph

I'm working on a shader in shader graph that uses the depth texture. As one may know, depth texture is ordinarily the z distance off the camera's plane, where it only takes one axis into account.

In my case however I need the actual true distance in world units. Online I've found in HLSL there is simply a function LinearEyeDepth() that does this. But I've tried many things in shader graph and so far none of them have worked. In my use case, things are grey in the center of the screen and shift to pitch black halfway to an edge. I'm working in URP.

 

if you need the distance why not just calculate the distance between the viewPos and fragment/vertex? shader graph gives you both in world space

 

Thank you for responding! I did realize yesterday that shader graph does have the world-relative position node that does exactly what I needed, after I watched an old HLSL video that talked about not needing depth texture for this sort of thing at all which sent me looking for alternatives.
