I need help with making 2 custom shaders work with URP 7.3.1

[Beast32704]

I have 2 Custom shaders that aren’t made for URP and I just want to know how to make them compatible with URP.

Shader "Custom/TerrainShader"
{
    Properties{
        _Color("Color", Color) = (1,1,1,1)
        _MainTex("Albedo (RGB)", 2D) = "white" {}
        _Glossiness("Smoothness", Range(0,1)) = 0.5
        _Metallic("Metallic", Range(0,1)) = 0.0
    }
    SubShader{
        Tags{ "RenderType" = "Opaque"}
        LOD 200
        Blend SrcAlpha OneMinusSrcAlpha

        CGPROGRAM
        #pragma surface surf Standard fullforwardshadows addshadow
        #pragma target 3.0

        sampler2D _MainTex;

        struct Input {
            float2 uv_MainTex;
            float4 color : Color;
        };

        half   _Glossiness;
        half   _Metallic;
        fixed4 _Color;
        half   _Alpha;

        void surf(Input IN, inout SurfaceOutputStandard o)
        {                       
            fixed4 c = IN.color;

            o.Albedo     = c;
            o.Metallic   = _Metallic;
            o.Smoothness = _Glossiness;
        }
        ENDCG
        }
        FallBack "Diffuse"
}

Heres my second one

Shader "Custom/WaterShader"
{
    Properties{
        _Color("Color", Color) = (1,1,1,1)
        _MainTex("Albedo (RGB)", 2D) = "white" {}
        _Glossiness("Smoothness", Range(0,1)) = 0.5
        _Metallic("Metallic", Range(0,1)) = 0.0
    }
    SubShader{
        Tags {"Queue" = "Transparent" "RenderType"="Transparent" }
        LOD 200
        Blend SrcAlpha OneMinusSrcAlpha

        CGPROGRAM
        #pragma surface surf Standard  fullforwardshadows alpha:fade
        #pragma target 3.0

        sampler2D _MainTex;

        struct Input {
            float2 uv_MainTex;
            float4 color : Color;
        };

        half   _Glossiness;
        half   _Metallic;
        fixed4 _Color;
        half   _Alpha;

        void surf(Input IN, inout SurfaceOutputStandard o)
        {                       
            fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
            o.Albedo = c.rgb;
            o.Metallic = _Metallic;
            o.Smoothness = _Glossiness;
            o.Alpha = c.a;
        }
        ENDCG
        }
        FallBack "Standard"
}

Hi Beast32704,
As you probably figured out, URP doesn’t support Surface shaders.
I would suggest you familiarize yourself with Shader Graph.
For instance, here is the second one(Water) you posted, recreated with Shader Graph(note: surface is set to Transparent).
You can dive deeper into Shader Graph here: How Shader Graph can be applied to your 2D or 3D game | Unity

The first one you posted is just a simplified version that uses vertex colors for Albedo.
Hope this helps!

(For terrain shader) Just add vertex color in shader graph link it with base color. Thats it…
