0503 쉐이더 UV

가로는 U, 세로는 V 

둘을 시각적으로 나타내기

void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D(_MainTex, IN.uv_MainTex);
            o.Albedo = IN.uv_MainTex.x;
            
        }
        ENDCG

void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D(_MainTex, IN.uv_MainTex);
            o.Albedo = IN.uv_MainTex.y;
            
        }
        ENDCG

 

0.5만큼 y축이 올라갔다.

둘이 한꺼번에 움직이도록 설정

 

x축으로만 흘러가도록 할 때

void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D(_MainTex, float2(IN.uv_MainTex.x + _Time.y, IN.uv_MainTex.y));
            o.Albedo = c.rgb;
            
        }
        ENDCG

 

y축으로만 흘러가도록 할때

void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D(_MainTex, float2(IN.uv_MainTex.x, IN.uv_MainTex.y + _Time.y));
            o.Albedo = c.rgb;
            
        }
        ENDCG

 

xy축 동시에 흘러가도록 할 때

 void surf (Input IN, inout SurfaceOutputStandard o)
        {
            fixed4 c = tex2D(_MainTex, float2(IN.uv_MainTex.x, IN.uv_MainTex.y)+_Time.y);
            o.Albedo = c.rgb;
            
        }
        ENDCG

 

흘러가는 속도를 조절하는 슬라이더 만들기
