Help with Converting to URP

Hello, I am working on a card game and I stumbled upon this really cool free asset:

https://assetstore.unity.com/packages/vfx/shaders/3d-game-card-146177

Unfortunately, this does not work in URP where I am building this project. I lack the shader skills to wrap my head around this, so I was wondering if there was anyone who could help me to convert this to be compatible in URP.

It's a free asset so I'm assuming it is okay to post the code:

Code (CSharp):

1. // Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'
2.  
3. Shader "Stencils/StencilMask" {
4.     Properties {
5.         [IntRange] _StencilMask("Stencil Mask", Range(0, 255)) = 0
6.     }
7.     SubShader {
8.         Tags {
9.             "RenderType" = "Opaque"
10.             "Queue" = "Geometry-100"
11.         }
12.         ColorMask 0
13.         ZWrite off
14.         Stencil {
15.             Ref[_StencilMask]
16.             Comp always
17.             Pass replace
18.         }
19.  
20.         Pass {
21.             CGPROGRAM
22.             #include "UnityCG.cginc"
23.  
24.             #pragma vertex vert
25.             #pragma fragment frag
26.  
27.             struct appdata {
28.                 float4 vertex : POSITION;
29.             };
30.  
31.             struct v2f {
32.                 float4 position : SV_POSITION;
33.             };
34.  
35.             v2f vert(appdata v) {
36.                 v2f o;
37.                 o.position = UnityObjectToClipPos(v.vertex);
38.                 return o;
39.             }
40.  
41.             half4 frag(v2f i) : COLOR {
42.                 return half4(1,1,0,1);
43.             }
44.             ENDCG
45.         }
46.     }
47. }

and then:

Code (CSharp):

1. Shader "Stencils/StencilObject" {
2.     Properties {
3.         [IntRange] _StencilMask("Stencil Mask", Range(0, 255)) = 0
4.  
5.         _Color ("Color", Color) = (1,1,1,1)
6.         _MainTex ("Albedo (RGB)", 2D) = "white" {}
7.         _Glossiness ("Smoothness", Range(0,1)) = 0.5
8.         _Metallic ("Metallic", Range(0,1)) = 0.0
9.     }
10.     SubShader {
11.         Tags { "RenderType"="Opaque" }
12.         LOD 200
13.         Stencil {
14.             Ref[_StencilMask]
15.             Comp equal
16.             Pass keep
17.             Fail keep
18.         }
19.  
20.         CGPROGRAM
21.  
22.         // Physically based Standard lighting model, and enable shadows on all light types
23.         #pragma surface surf Standard fullforwardshadows
24.  
25.         // Use shader model 2.0 target, to get nicer looking lighting
26.         #pragma target 2.0
27.  
28.         sampler2D _MainTex;
29.  
30.         struct Input {
31.             float2 uv_MainTex;
32.         };
33.  
34.         half _Glossiness;
35.         half _Metallic;
36.         fixed4 _Color;
37.  
38.         void surf (Input IN, inout SurfaceOutputStandard o) {
39.  
40.             // Albedo comes from a texture tinted by color
41.             fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
42.             o.Albedo = c.rgb;
43.  
44.             // Metallic and smoothness come from slider variables
45.             o.Metallic = _Metallic;
46.             o.Smoothness = _Glossiness;
47.             o.Alpha = c.a;
48.         }
49.         ENDCG
50.     }
51.     FallBack "Diffuse"
52. }
53.  

Any help would be much appreciated. Thanks.

 

Thank you so much! You explained everything so well I'm now less afraid of shaders. Cheers!
