Resolved Screen Depth with URP

Hi guys!

I've created a URP project with unity 2021.1.6.
In the sample scene, I've created a plane (CastShadow: false) with a material with a URP lit shader graph.
In the settings files I've checked General/Depth Texture ans General/Opaque Texture.
I've followed this tutorial step by step:
https://fr.indietrainers.com/video/making-a-water-shader-in-unity-with-urp-tutorial
... but nothing appends when I use the Screen Depth node.

What am I missing

Notes:

• As soon as I created the shader graph, in the inspector I can read :

"use of potentially uninitialized variable (AdditionalLightRealtimeShadow) D3D Shadows.hlsl:325"

• I tryed two other Screen Depth tutorials and still nothing

Regards,
Florent

 

I forgot to put Screen Position into Raw mode
