[5.7] 외곽선 연습

1. 두께와 색깔을 조절할 수 있는 Property 만들기

결과 및 Inspector

Shader "Custom/Test"
{
    Properties
    {
        _Color ("Color", Color) = (1,1,1,1)
        _StrokePower ("Stroke Power", Float) = 1
        _MainTex ("Albedo (RGB)", 2D) = "white" {}
    }
    SubShader
    {
        Tags { "RenderType"="Opaque" }
        
        Cull Front

        CGPROGRAM
        #pragma surface surf NoLight noshadow noambient vertex:vert

        float _StrokePower;
        fixed4 _Color;

        void vert(inout appdata_full v)
        {
            v.vertex.xyz += v.normal.xyz * _StrokePower / 100;
        }

        struct Input
        {
            float4 color:Color;
        };
        
        void surf (Input IN, inout SurfaceOutput o)
        {
            
        }

        float4 LightingNoLight(SurfaceOutput s, float3 lightDir, float atten)
        {
            return float4(_Color.rgb, 1);
        }
        ENDCG
        
        Cull Back
        CGPROGRAM
        #pragma surface surf Standard fullforwardshadows

        sampler2D _MainTex;

        struct Input
        {
            float2 uv_MainTex;
        };

        void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D (_MainTex, IN.uv_MainTex);
            o.Albedo = c.rgb;
            o.Alpha = c.a;
        }
        ENDCG
    }
    FallBack "Diffuse"
}

 

2. 외곽선 컬러나 두께에 애니메이션 넣기 (임시)

Shader "Custom/Test"
{
    Properties
    {
        _Color ("Color", Color) = (1,1,1,1)
        _StrokePower ("Stroke Power", Float) = 1
        _Sample ("Sample", 2D) = "white" {}
        _MainTex ("Albedo (RGB)", 2D) = "white" {}
    }
    SubShader
    {
        Tags { "RenderType"="Opaque" }
        
        Cull Front

        CGPROGRAM
        #pragma surface surf NoLight noshadow noambient vertex:vert

        sampler2D _MainTex; 
        sampler2D _Sample;
        float _StrokePower;
        fixed4 _Color;

        void vert(inout appdata_full v)
        {
            v.vertex.xyz += v.normal.xyz * _StrokePower / 100;
        }

        struct Input
        {
            float2 uv_MainTex;
            float2 uv_Sample;
            float4 color:Color;
        };
        
        void surf (Input IN, inout SurfaceOutput o)
        {
            fixed4 c = tex2D (_Sample, IN.uv_Sample -  _Time.y * 0.5);
            o.Emission = float4(_Color.rgb, 1) * c.b * 3;
            o.Alpha = 0;
        }

        float4 LightingNoLight(SurfaceOutput s, float3 lightDir, float atten)
        {
            return float4(s.Emission, s.Alpha);
        }
        ENDCG
        
        Cull Back
        CGPROGRAM
        #pragma surface surf Standard fullforwardshadows

        sampler2D _MainTex;

        struct Input
        {
            float2 uv_MainTex;
        };

        void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D (_MainTex, IN.uv_MainTex);
            o.Albedo = c.rgb;
            o.Alpha = c.a;
        }
        ENDCG
    }
    FallBack "Diffuse"
}

색깔은 uv에 없어서 어떻게 해야할지 감이 잘 오지 않는다.

코드에서 쓴 방법말고 다른 방법이 있을것 같다.
