    I'm trying to make a replacement shader thats using UsePass function, but I need to select which pass to use by material, for example if the material Have certain keyword, use all passes, if don't have use only shadow caster pass.
    Code (CSharp):
    1.  
    2.     SubShader
    3.    {
    4.        Tags { "RenderType"="Opaque" }
    5.    LOD 0
    6.  
    7.        Cull Off
    8.        CGINCLUDE
    9.        #pragma target 5.0
    10.        #pragma multi_compile __ _SHADERTYPE_BODY_ON
    11.        ENDCG
    12.      
    13.        #ifdef _SHADERTYPE_BODY_ON
    14.  
    15.        UsePass "Myshader/LightingPassNode/FORWARDBASE"
    16.        UsePass "Myshader/LightingPassNode/FORWARDADD"
    17.        UsePass "Myshader/LightingPassNode/SHADOWCASTER"
    18.        #else
    19.        UsePass "Myshader/LightingPassNode/SHADOWCASTER"
    20.  
    21.        #endif
    22.  
    23.    }
    24.  
    But using ifdef condition failed to compile. How I can work around this?
