## Shader代码 ##

Shader "CustomUI/FirstText"
    {
    	Properties
    	{
    		_MainTex ("Font Texture", 2D) = "white" {}  
    			//MASK SUPPORT ADD
    	_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
    		//MASK SUPPORT END
    	}
    
    
    	SubShader {  
            Tags { "Queue" = "Overlay"
    		"IgnoreProjector" = "True"
    		"RenderType" = "Transparent"

    		"CanUseSpriteAtlas" = "True" }  
    		//MASK SUPPORT ADD
    		Stencil
    	{
    		Ref[_Stencil]
    		Comp[_StencilComp]
    		Pass[_StencilOp]
    		ReadMask[_StencilReadMask]
    		WriteMask[_StencilWriteMask]
    	}
    		ColorMask[_ColorMask]
    		//MASK SUPPORT END
           Cull Off
    		Lighting Off
    		ZWrite Off
    		ZTest Always
    		Fog{ Mode Off }
    		Blend SrcAlpha OneMinusSrcAlpha
            Pass {  
                SetTexture [_MainTex] {  
                    combine primary, texture * primary  
                }  
            }  
        }  
    }

实现字卡在模型中能穿透显示

当字为模型的背景时：即世界坐标中，字在前，模型在后，但是模型能遮挡字

Shader "CustomUI/BgText"
    {
    	Properties
    	{
    		_MainTex("Font Texture", 2D) = "white" {}
    	//MASK SUPPORT ADD
    	_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
    		//MASK SUPPORT END
    	}
    
    
    		SubShader{
    		Tags{ "Queue" = "Background"
    		"IgnoreProjector" = "True"
    		"RenderType" = "Transparent"
    		"PreviewType" = "Plane"
    		"CanUseSpriteAtlas" = "True" }
    
    		//MASK SUPPORT ADD
    		Stencil
    	{
    		Ref[_Stencil]
    		Comp[_StencilComp]
    		Pass[_StencilOp]
    		ReadMask[_StencilReadMask]
    		WriteMask[_StencilWriteMask]
    	}
    		ColorMask[_ColorMask]
    		//MASK SUPPORT END
    
    
    		Cull Off
    		Lighting Off
    		ZWrite Off
    		ZTest Always
    		Fog{ Mode Off }
    		Blend SrcAlpha OneMinusSrcAlpha
    		Pass{
    		//Color[_Color]
    		SetTexture[_MainTex]{
    		combine primary, texture * primary
    	}
    	}
    	}
    }
