写一个支持urp的溶解shader写一个半卡通shader

支持URP的溶解Shader:

Shader "Custom/DissolveURP" { Properties { _MainTex ("Texture", 2D) = "white" {} _DissolveTex ("Dissolve Texture", 2D) = "white" {} _DissolveColor ("Dissolve Color", Color) = (1,1,1,1) _DissolveAmount ("Dissolve Amount", Range(0,1)) = 0.5 }

SubShader {
    Tags {"Queue"="Transparent" "RenderType"="Transparent"}

    Pass {
        CGPROGRAM
        #pragma vertex vert
        #pragma fragment frag
        #include "UnityCG.cginc"

        struct appdata {
            float4 vertex : POSITION;
            float2 uv : TEXCOORD0;
        };

        struct v2f {
            float2 uv : TEXCOORD0;
            float4 vertex : SV_POSITION;
        };

        sampler2D _MainTex;
        sampler2D _DissolveTex;
        float4 _DissolveColor;
        float _DissolveAmount;

        v2f vert (appdata v) {
            v2f o;
            o.vertex = UnityObjectToClipPos(v.vertex);
            o.uv = v.uv;
            return o;
        }

        fixed4 frag (v2f i) : SV_Target {
            float4 tex = tex2D(_MainTex, i.uv);
            float4 dissolve = tex2D(_DissolveTex, i.uv);
            float4 dissolveColor = lerp(tex, _DissolveColor, dissolve.r * _DissolveAmount);
            dissolveColor.a = tex.a;
            return dissolveColor;
        }
        ENDCG
    }
}
FallBack "Diffuse"

}

半卡通Shader:

Shader "Custom/HalfToon" { Properties { _MainTex ("Texture", 2D) = "white" {} _Color ("Color", Color) = (1,1,1,1) _RampTex ("Ramp Texture", 2D) = "white" {} _ShadowColor ("Shadow Color", Color) = (0,0,0,1) }

SubShader {
    Tags {"Queue"="Transparent" "RenderType"="Transparent"}

    Pass {
        CGPROGRAM
        #pragma vertex vert
        #pragma fragment frag
        #include "UnityCG.cginc"

        struct appdata {
            float4 vertex : POSITION;
            float2 uv : TEXCOORD0;
        };

        struct v2f {
            float2 uv : TEXCOORD0;
            float4 vertex : SV_POSITION;
        };

        sampler2D _MainTex;
        sampler2D _RampTex;
        float4 _Color;
        float4 _ShadowColor;

        v2f vert (appdata v) {
            v2f o;
            o.vertex = UnityObjectToClipPos(v.vertex);
            o.uv = v.uv;
            return o;
        }

        fixed4 frag (v2f i) : SV_Target {
            float4 tex = tex2D(_MainTex, i.uv);
            float4 ramp = tex2D(_RampTex, float2(tex.r, 0.5));
            float4 color = _Color * tex;
            float4 shadow = _ShadowColor * (1 - ramp.r);
            return color + shadow;
        }
        ENDCG
    }
}
