Question Help upgrading shader to URP

Hey. I have little to no experience with shaders, but I'm forced to work . For an upcoming game, I needed a texture that can be procedurally generated with information from vertices and colors. I have found this shader on a forum, and it worked fine until I upgraded from the Built-In render engine to the URP engine.

Code (CSharp):

1. Shader "PlanetShader"
2. {
3.     Properties
4.     {
5.         [HideInInspector] __dirty( "", Int ) = 1
6.     }
7.  
8.     SubShader
9.     {
10.         Tags{ "RenderType" = "Opaque"  "Queue" = "Geometry+0" }
11.         Cull Back
12.         CGPROGRAM
13.         #pragma target 3.0
14.         #pragma surface surf Standard keepalpha addshadow fullforwardshadows
15.         struct Input
16.         {
17.             float4 vertexColor : COLOR;
18.         };
19.  
20.         void surf( Input i , inout SurfaceOutputStandard o )
21.         {
22.             o.Albedo = i.vertexColor.rgb;
23.             o.Alpha = 1;
24.         }
25.  
26.         ENDCG
27.     }
28.     Fallback "Diffuse"
29.     CustomEditor "ASEMaterialInspector"
30. }

I would appreciate it if someone could explain to me what exactly it does, and how an upgrade to URP would look like.

 

It's a standard shader that plugs the vertex colors into albedo.

Use the Shader Graph and plug the Vertex Color Node into albedo.

 

Is this what you mean by chance? The objects just seem to appear as black, I'm unsure if it's the generator script causing it or if it is this shader graph.
(I couldn't find albedo, am I missing something?)

 

You’re not missing something, I just keep forgetting they changed the terminology for SRP. The graph looks correct, not sure why it’s not working.

 

Eventually got it working modifying some atmosphere settings. Thanks!
