标题: 给物体添加一个明暗变化效果的shader
个不错的shader，可以为场景的物体添加一个渐变明暗效果，下面是截图：

下面是shader代码:

Shader "Hidden/TerrainEngine/BillboardTree" {

Properties {

  _MainTex ("Base (RGB) Alpha (A)", 2D) = "white" {}

}
SubShader {

  Tags { "Queue" = "Transparent-100" "IgnoreProjector"="***e" "RenderType"="TreeBillboard" }



  Pass {

ColorMask rgb

Blend SrcAlpha OneMinusSrcAlpha

ZWrite Off Cull Off

CGPROGRAM

#pragma vertex vert

#include "UnityCG.cginc"

#include "TerrainEngine.cginc"

#pragma fragment frag
s***ct v2f {

float4 pos : POSITION;

fixed4 color : COLOR0;

float2 uv : TEXCOORD0;

};
v2f vert (appdata_tree_billboard v) {

v2f o;

TerrainBillboardTree(v.vertex, v.texcoord1.xy, v.texcoord.y);

o.pos = mul (UNITY_MATRIX_MVP, v.vertex);

o.uv.x = v.texcoord.x;

o.uv.y = v.texcoord.y > 0;

o.color = v.color;

o.color *= o.uv.y;

return o;

}
sampler2D _MainTex;

fixed4 frag(v2f input) : COLOR

{

fixed4 col = tex2D( _MainTex, input.uv);

col.rgb *= input.color.rgb;

clip(col.a);

return col;

}

ENDCG

  }

}
SubShader {

  Tags { "Queue" = "Transparent-100" "IgnoreProjector"="***e" "RenderType"="TreeBillboard" }



  Pass {
CGPROGRAM

#pragma vertex vert

#pragma exclude_renderers shaderonly

#include "UnityCG.cginc"

#include "TerrainEngine.cginc"
s***ct v2f {

float4 pos : POSITION;

fixed4 color : COLOR0;

float2 uv : TEXCOORD0;

};
v2f vert (appdata_tree_billboard v) {

v2f o;

TerrainBillboardTree(v.vertex, v.texcoord1.xy, v.texcoord.y);

o.pos = mul (UNITY_MATRIX_MVP, v.vertex);

o.uv.x = v.texcoord.x;

o.uv.y = v.texcoord.y > 0;

o.color = v.color;

return o;

}

ENDCG
ColorMask rgb

Blend SrcAlpha OneMinusSrcAlpha

ZWrite Off Cull Off

AlphaTest Greater 0

SetTexture [_MainTex] { combine texture * primary, texture }

  }

}
Fallback Off

}
