头像使用了为材质动态加载贴图。为了实现灰色效果,网上找了段着色器。
Shader "GrayscaleLol" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 200
CGPROGRAM
#pragma surface surf Lambert
sampler2D _MainTex;
struct Input {
float2 uv_MainTex;
};
void surf (Input IN, inout SurfaceOutput o) {
half4 c = tex2D (_MainTex, IN.uv_MainTex);
o.Albedo = (c.r + c.g + c.b)/3;
o.Alpha = c.a;
}
ENDCG
}
FallBack "Diffuse"
}
