ugui 灰度shader mask冲突解决 转。。。

项目上遇到了一个问题,灰度shader无法在mask下使用,两个之间会一定的冲突。经查验是mask组件对shader的相关属性有要求,添加相关的属性则可符合要求使其他shader使用UGui里的mask。

  1. Shader "Custom/Opaque"
  2. {
  3. Properties
  4. {
  5. [PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {}
  6. _Color ("Tint", Color) = (1,1,1,1)
  7. // required for UI.Mask
  8. _StencilComp ("Stencil Comparison", Float) = 8
  9. _Stencil ("Stencil ID", Float) = 0
  10. _StencilOp ("Stencil Operation", Float) = 0
  11. _StencilWriteMask ("Stencil Write Mask", Float) = 255
  12. _StencilReadMask ("Stencil Read Mask", Float) = 255
  13. _ColorMask ("Color Mask", Float) = 15
  14. }
  15. SubShader
  16. {
  17. Tags
  18. {
  19. // ...
  20. }
  21. // required for UI.Mask
  22. Stencil
  23. {
  24. Ref [_Stencil]
  25. Comp [_StencilComp]
  26. Pass [_StencilOp]
  27. ReadMask [_StencilReadMask]
  28. WriteMask [_StencilWriteMask]
  29. }
  30. ColorMask [_ColorMask]
  31. Pass
  32. {
  33. // ...
  34. }
  35. }
  36. }

 

 

 

 

 

完整代码如下:

Shader "Unlit/graytest"
{
Properties
{
_MainTex ("Texture", 2D) = "white" {}
_StencilComp("Stencil Comparison", Float) = 8
_Stencil("Stencil ID", Float) = 0
_StencilOp("Stencil Operation", Float) = 0
_StencilWriteMask("Stencil Write Mask", Float) = 255
_StencilReadMask("Stencil Read Mask", Float) = 255
_ColorMask("Color Mask", Float) = 15
_LayerDepth("LayerDepth", Float) = 15
}

SubShader
{
Tags { "RenderType"="Opaque""Queue"="Geometry" }
LOD 100
Stencil
{
Ref[_Stencil]
Comp[_StencilComp]
Pass[_StencilOp]
ReadMask[_StencilReadMask]
WriteMask[_StencilWriteMask]
}
ColorMask[_ColorMask]
Pass
{
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
// make fog work
#pragma multi_compile_fog

#include "UnityCG.cginc"

struct appdata
{
float4 vertex : POSITION;
float2 uv : TEXCOORD0;
};

struct v2f
{
float2 uv : TEXCOORD0;
UNITY_FOG_COORDS(1)
float4 vertex : SV_POSITION;
};

sampler2D _MainTex;
float4 _MainTex_ST;

v2f vert (appdata v)
{
v2f o;
o.vertex = UnityObjectToClipPos(v.vertex);
o.uv = TRANSFORM_TEX(v.uv, _MainTex);
UNITY_TRANSFER_FOG(o,o.vertex);
return o;
}

fixed4 frag (v2f i) : SV_Target
{
// sample the texture
fixed4 c = tex2D(_MainTex, i.uv);
fixed4 col = c.r*0.3 + c.g*0.59 + c.b*0.11;
// apply fog
UNITY_APPLY_FOG(i.fogCoord, col);
return col;
}
ENDCG
}
}
}
