0507 _ 툰쉐이더 _ 1pass로 음영 표시하기

새로 만들어서 텍스쳐 한장을 받는 스크립터를 만들어준다.

 

 

커스텀 라이팅을 해줍니다 .

Rim 만들어주기

 

Shader "Custom/Test"
{
    Properties
    {
       
        _MainTex ("Albedo (RGB)", 2D) = "white" {}
    }
    SubShader
    {
        Tags { "RenderType"="Opaque" }
        LOD 200

        CGPROGRAM

        #pragma surface surf _Toon noambient

        #pragma target 3.0

        sampler2D _MainTex;

        struct Input
        {
            float2 uv_MainTex;
        };


        void surf (Input IN, inout SurfaceOutput o)
        {

            fixed4 c = tex2D (_MainTex, IN.uv_MainTex);
            o.Albedo = c.rgb;
            o.Alpha = c.a;
        }
        float4 Lighting_Toon(SurfaceOutput s, float3 lightDir, float3 viewDir, float atten){
            //half-lambert
            float ndotl = dot(s.Normal, lightDir) *0.5 +0.5;
            ndotl = ndotl * 5;
            ndotl = ceil(ndotl) / 5;


            //Rim
            float rim = dot(s.Normal, viewDir);

            float4 final;
            final.rgb = ndotl * s.Albedo;
            final.a = s.Alpha;

            return rim;
        }
        ENDCG
    }
    FallBack "Diffuse"
}

 

 

 

Rim을 이용해서 1pass로 외곽선 만들어 줄 수 있다.

            ndotl = ceil(ndotl) / 5;


            //Rim
            float rim = abs(dot(s.Normal, viewDir));
            if(rim > 0.3){
                rim = 1;
            }
            else{
                rim = -1;
            }

            float4 final;
            final.rgb = ndotl * s.Albedo;
